}
}
CommentInfoView类如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace WPF练习13简单的项目.Model.View
{
public class CommentInfoView : CommentInfo
{
public string DataStatusText { get; set; }

{
public class PostInfoView : PostInfo
{
public string BlogTypeName { get; set; }
public string DataStatusText { get; set; }
public string CreateUserName { get; set; }
public int LastUpdateUserName { get; set; }
}
}
UserInfoView类如下:

{
public class UserInfoView : UserInfo
{
public string DataStatusText { get; set; }
public string CreateUserName { get; set; }
public int LastUpdateUserName { get; set; }
}
}
第四步:在View文件夹中的UserControls文件夹中创建BlogType.XAML、Comment.XAML、Post.XAML、User.XAML
User.XAML如下:
<UserControl x:Class="WPF练习13简单的项目.View.UserControls.User"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:WPF练习13简单的项目.View.UserControls"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800">
<Grid>
<TextBlock Text="1" />
</Grid>
</UserControl>
Post.XAML如下:
<UserControl x:Class="WPF练习13简单的项目.View.UserControls.Post"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:WPF练习13简单的项目.View.UserControls"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800">
<Grid>
<TextBlock Text="4" />
</Grid>
</UserControl>
第五步:在Service文件夹下创建IBase 、IBlogTypeInfo、ICommentInfo、IPostInfo、IUserInfo
IBase如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace WPF练习13简单的项目.Service
{
public interface IBase<T,K>
{
/// <summary>
/// 添加数据
/// </summary>
/// <param name="model">模型</param>
/// <returns>布尔</returns>
bool Add(T model);
/// <summary>
/// 删除
/// </summary>
/// <param name="id">主键</param>
/// <returns>布尔</returns>
bool Delete(int id);
/// <summary>
/// 分页获取数据
/// </summary>
/// <param name="strWhere">查询条件</param>
/// <param name="orderBy">排序字段</param>
/// <param name="startIndex">起始索引</param>
/// <param name="endIndex">结束索引</param>
/// <returns>列表,关联视图模型K</returns>
List<K> GetListByPage(string strWhere, string orderBy, int startIndex, int endIndex);
/// <summary>
/// 获取单个模型
/// </summary>
/// <param name="id">主键</param>
/// <returns>泛型T</returns>
T GetModel(int id);
/// <summary>
/// 修改
/// </summary>
/// <param name="model">模型</param>

namespace WPF练习13简单的项目.Service
{
public interface IBlogTypeInfo : IBase<BlogTypeInfo, BlogTypeInfoView>
{
}
}
ICommentInfo如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WPF练习13简单的项目.Model.View;
using WPF练习13简单的项目.Model;
namespace WPF练习13简单的项目.Service
{
public interface ICommentInfo : IBase<CommentInfo, CommentInfoView>
{
}
}
IPostInfo如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WPF练习13简单的项目.Model.View;

return conn.Execute(sql, model) > 0;
}
}
}
}
PostInfoService如下:
using Dapper;
using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WPF练习13简单的项目.Helper;

return conn.Execute(sql, model) > 0;
}
}
}
}
UserInfoService如下:
using Dapper;
using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WPF练习13简单的项目.Helper;

}
public bool Delete(int id)
{
using (var conn = new SqlConnection(ConstHelper.ConnString))
{
conn.Open();
var sql = "UPDATE UserInfo Set DataStatus=1 WHERE UserId=@UserId";
var param = new { UserId = id };
return conn.Execute(sql, param) > 0;
}
}
public List<UserInfoView> GetListByPage(string strWhere, string orderBy, int startIndex, int endIndex)
{
using (var conn = new SqlConnection(ConstHelper.ConnString))
{
conn.Open();
StringBuilder sql = new StringBuilder();
sql.Append("SELECT * FROM ( ");
sql.Append(" SELECT ROW_NUMBER() OVER (");

return conn.Execute(sql, model) > 0;
}
}
}
}
第七步:在App.cs文件中放入想要放入Ioc容器的对象
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;
using WPF练习13简单的项目.Service;
using WPF练习13简单的项目.ServiceImpl;
using WPF练习13简单的项目.View;
using WPF练习13简单的项目.View.UserControls;
namespace WPF练习13简单的项目
{
/// <summary>
/// App.xaml 的交互逻辑
/// </summary>
public partial class App : Application
{
public IServiceProvider Services { get; }
public App()
{
Services = ConfigurationServices();
}
public static new App Current { get { return (App)Application.Current; } }
private IServiceProvider ConfigurationServices()
{
ServiceCollection services = new ServiceCollection();
// 放窗体
services.AddSingleton<Main>();
// 放用户控件
services.AddSingleton<BlogType>();
services.AddSingleton<Comment>();
services.AddSingleton<Post>();
services.AddSingleton<User>();
// 放服务
services.AddSingleton<IBlogTypeInfo, BlogTypeInfoService>();
services.AddSingleton<ICommentInfo, CommentInfoService>();
services.AddSingleton<IPostInfo, PostInfoService>();
services.AddSingleton<IUserInfo, UserInfoService>();
return services.BuildServiceProvider();
}
}
}
第八步:在Helper文件夹中创建LoginInfoHelper类存放登录的用户 并在ViewModel创建LoginViewModel类和MainViewModel类
using CTMVVMDemo.Model;
namespace CTMVVMDemo.Helper
{
public static class LoginInfoHelper
{
public static UserInfo CurrentUser { get; set; }
}
}
LoginViewModel如下:
using CommunityToolkit.Mvvm.ComponentModel;
using CommunityToolkit.Mvvm.Input;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Security;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using WPF练习13简单的项目.Helper;
using WPF练习13简单的项目.Model;
using WPF练习13简单的项目.Service;
using WPF练习13简单的项目.View;
namespace WPF练习13简单的项目.ViewModel
{
public class LoginViewModel : ObservableObject
{
private readonly IUserInfo userService;
public LoginViewModel()
{
userService = App.Current.Services.GetService<IUserInfo>();
}
private string userName;
public string UserName
{
get => userName;
set => SetProperty(ref userName, value);
}
private SecureString password;
public SecureString Password
{
get => password;
set => SetProperty(ref password, value);
}
public RelayCommand<Login> LoginCommand
{
get
{
return new RelayCommand<Login>((loginWin) =>
{
Button btnLogin = loginWin.FindName("btnLogin") as Button;
if (btnLogin != null) btnLogin.Focus();
UserInfo userInfo = userService.Login(UserName, SecureStringToString(Password));
if (userInfo == null)
{
MessageBox.Show("登录失败,请检查账号或密码是否正确!", "错误", System.Windows.MessageBoxButton.OK, MessageBoxImage.Error);
return;
}
LoginInfoHelper.CurrentUser = userInfo;
loginWin.Hide();
var mainWin = App.Current.Services.GetService<Main>();
mainWin.Show();
});
}
}
public RelayCommand<object> PasswordChangedCommand
{
get
{
return new RelayCommand<object>((obj) =>
{
var passwordBox = obj as PasswordBox;
if (passwordBox != null) Password = passwordBox.SecurePassword;
});
}
}
/// <summary>
/// 将 SecureString 类型的数据转换为普通的字符串类型。 https://www.cnblogs.com/CDRPS/p/18156533
/// </summary>
/// <param name="secureString">要转换的 SecureString 对象。</param>
/// <returns>转换后的字符串,如果转换失败则返回空字符串。</returns>
private string SecureStringToString(SecureString secureString)
{
// 初始化指针
IntPtr ptr = IntPtr.Zero;
try
{
// 将 SecureString 转换为指针
ptr = Marshal.SecureStringToGlobalAllocUnicode(secureString);
if (ptr != IntPtr.Zero)
{
// 将指针中的数据复制到一个普通的字符串
return Marshal.PtrToStringUni(ptr);
}
else
{
return string.Empty;
}
}
catch (Exception ex)
{
// 处理异常
Console.WriteLine($"转换 SecureString 出错:{ex.Message}");
return string.Empty;
}
finally
{
// 清除内存中的敏感数据
if (ptr != IntPtr.Zero)
{
Marshal.ZeroFreeGlobalAllocUnicode(ptr);
}
}
}
}
}
MainViewModel如下:
using CommunityToolkit.Mvvm.ComponentModel;
using CommunityToolkit.Mvvm.Input;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Controls;
using WPF练习13简单的项目.Helper;
using WPF练习13简单的项目.Model;
using WPF练习13简单的项目.Service;
using WPF练习13简单的项目.View.UserControls;
namespace WPF练习13简单的项目.ViewModel
{
public class MainViewModel: ObservableObject
{
private readonly IUserInfo userService;
public MainViewModel()
{
userService = App.Current.Services.GetService<IUserInfo>();
CurrentUser = LoginInfoHelper.CurrentUser;
WhichUserControl = App.Current.Services.GetService<User>();
}
private UserInfo currentUser;
public UserInfo CurrentUser
{
get => currentUser;
set => SetProperty(ref currentUser, value);
}
private UserControl whichUserControl;
public UserControl WhichUserControl
{
get => whichUserControl;
set => SetProperty(ref whichUserControl, value);
}
public RelayCommand<string> ToggleCommand
{
get
{
return new RelayCommand<string>((str) =>
{
switch (str)
{
case "用户管理":
WhichUserControl = App.Current.Services.GetService<User>();
break;
case "博客类型":
WhichUserControl = App.Current.Services.GetService<BlogType>();
break;
case "博客管理":
WhichUserControl = App.Current.Services.GetService<Post>();
break;
case "评论管理":
WhichUserControl = App.Current.Services.GetService<Comment>();
break;
default:
WhichUserControl = App.Current.Services.GetService<User>();
break;
}
});
}
}
public RelayCommand ClosedCommand
{
get
{
return new RelayCommand(() =>
{
App.Current.Shutdown();
});
}
}
}
}
第九步:在Login.XAML和Main.XAML中写对应的前端代码
1.在Dict文件夹中创建LoginDictionary.xaml存放登录窗口的样式
LoginDictionary.xaml如下:
<Application x:Class="WPF练习13简单的项目.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPF练习13简单的项目"
StartupUri="View/Login.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dict/LoginDictionary.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style x:Key="ButtonDefault"
TargetType="Button">
<Setter Property="FocusVisualStyle"
Value="{x:Null}" />
<Setter Property="Width"
Value="80" />
<Setter Property="Height"
Value="30" />
<Setter Property="Foreground"
Value="#ffffff" />
<Setter Property="Background"
Value="#9e6f55" />
<Setter Property="BorderThickness"
Value="0" />
</Style>
<Style x:Key="TextBoxDefault"
TargetType="TextBox">
<Setter Property="Width"
Value="150" />
<Setter Property="Height"
Value="30" />
<Setter Property="VerticalContentAlignment"
Value="Center" />
<Setter Property="Padding"
Value="10,0,0,0" />
<Setter Property="BorderBrush"
Value="#9e6f55" />
</Style>
<Style x:Key="PasswordBoxDefault"
TargetType="PasswordBox">
<Setter Property="Width"
Value="150" />
<Setter Property="Height"
Value="30" />
<Setter Property="VerticalContentAlignment"
Value="Center" />
<Setter Property="Padding"
Value="10,0,0,0" />
<Setter Property="BorderBrush"
Value="#9e6f55" />
</Style>
</ResourceDictionary>
</Application.Resources>
</Application>
2.App.XAML文件中存在共同的样式以及存放LoginDictionary.xaml的引用
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dict/LoginDictionary.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style x:Key="ButtonDefault"
TargetType="Button">
<Setter Property="FocusVisualStyle"
Value="{x:Null}" />
<Setter Property="Width"
Value="80" />
<Setter Property="Height"
Value="30" />
<Setter Property="Foreground"
Value="#ffffff" />
<Setter Property="Background"
Value="#9e6f55" />

3.在Login.XAML文件中创建上下文并创建基本样式
<Window x:Class="WPF练习13简单的项目.View.Login"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WPF练习13简单的项目.View"
xmlns:vm="clr-namespace:WPF练习13简单的项目.ViewModel"
xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
d:DataContext="{d:DesignInstance Type=vm:LoginViewModel}"
FocusManager.FocusedElement="{Binding ElementName=txtUserName}"
mc:Ignorable="d"
Title="Login"
Height="450"
Width="800">
<Window.DataContext>
<vm:LoginViewModel />
</Window.DataContext>
<Grid HorizontalAlignment="Center"
VerticalAlignment="Center">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<WrapPanel>
<Label Content="账号:" />
<TextBox Name="txtUserName"
Style="{StaticResource TextBoxDefault}"
Template="{DynamicResource TextBoxTemplate}"
Text="{Binding UserName}" />
</WrapPanel>
<WrapPanel Grid.Row="1"
Margin="0,10,0,0">
<Label Content="密码:" />
<PasswordBox Name="PasswordBox"
Style="{StaticResource PasswordBoxDefault}"
Template="{DynamicResource PasswordBoxTemplate}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="PasswordChanged">
<i:InvokeCommandAction Command="{Binding PasswordChangedCommand}"

</i:EventTrigger>
</i:Interaction.Triggers>
</PasswordBox>
</WrapPanel>
<WrapPanel Grid.Row="2"
Margin="0,10,0,0"
HorizontalAlignment="Center">
<Button Name="btnLogin"
Command="{Binding LoginCommand}"
CommandParameter="{Binding RelativeSource={RelativeSource AncestorType=Window}}"
Content="登录"

Style="{StaticResource ButtonDefault}"
Template="{DynamicResource ButtonTemplate}" />
</WrapPanel>
</Grid>
</Window>
4.在Main.XAML文件中创建上下文并创建基本样式
<Window x:Class="WPF练习13简单的项目.View.Main"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

d:DataContext="{d:DesignInstance Type=vm:MainViewModel}"
WindowStartupLocation="CenterScreen"
mc:Ignorable="d"
Title="Main"
Height="450"
Width="800">
<Window.DataContext>
<vm:MainViewModel />
</Window.DataContext>
<i:Interaction.Triggers>
<i:EventTrigger EventName="Closed">
<i:InvokeCommandAction Command="{Binding ClosedCommand}" />
</i:EventTrigger>
</i:Interaction.Triggers>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="60" />
<RowDefinition />
</Grid.RowDefinitions>
<Grid Background="#f4eeee">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="200" />
</Grid.ColumnDefinitions>
<WrapPanel VerticalAlignment="Center">

Template="{DynamicResource ButtonTemplate}" />
</WrapPanel>
</Grid>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="160" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<StackPanel Background="#9e6f55">
<Button Width="160"
Margin="0,10,0,10"
Command="{Binding ToggleCommand}"
CommandParameter="用户管理"
Content="用户管理"
Style="{StaticResource ButtonDefault}"
Template="{DynamicResource ButtonTemplate}" />
<Button Width="160"
Margin="0,0,0,10"
