staticResource和dynamicResource的区别
首先看一个案例
MainWindow.xaml
<Window x:Class="WpfDay03.MainWindow"
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:WpfDay03"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Window.Resources>
<SolidColorBrush x:Key="SolidColor" Color="Red"/>
</Window.Resources>
<Grid>
<StackPanel>
<Button Content="update" Margin="5" Click="Button_Click"></Button>
<Button Content="btn1" Margin="5" BorderBrush="{StaticResource SolidColor}" BorderThickness="5"></Button>
<Button Content="btn2" Margin="5" BorderBrush="{DynamicResource SolidColor}" BorderThickness="5"></Button>
</StackPanel>
</Grid>
</Window>MainWindow.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfDay03
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
this.Resources["SolidColor"] = new SolidColorBrush(Colors.Blue);
}
}
}当update按钮点击之后只有使用动态资源的btn2边框颜色改变，而使用静态资源的btn1不发生改变。
将样式单独写在xaml中
ButtonStyle.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<SolidColorBrush x:Key="SolidColor" Color="Red"/>
<Style x:Key="DefaultButtonStyle" TargetType="Button">
<Setter Property="Foreground" Value="Blue"></Setter>
<Setter Property="FontSize" Value="15"></Setter>
</Style>
</ResourceDictionary>需要在App.xaml中添加该资源字典
<Application x:Class="WpfDay03.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfDay03"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ButtonStyle.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>MainWindow.xaml
<Window x:Class="WpfDay03.MainWindow"
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:WpfDay03"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Grid>
<StackPanel>
<Button Content="update" Margin="5" Click="Button_Click"></Button>
<Button Content="btn1" Margin="5" BorderBrush="{StaticResource SolidColor}" BorderThickness="5"></Button>
<Button Content="btn2" Margin="5" BorderBrush="{DynamicResource SolidColor}" BorderThickness="5"></Button>
<Button Content="useStyle" Margin="5" Style="{StaticResource DefaultButtonStyle}"></Button>
</StackPanel>
</Grid>
</Window>MainWindow.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;

}
private void Button_Click(object sender, RoutedEventArgs e)
{
this.Resources["SolidColor"] = new SolidColorBrush(Colors.Blue);
//查看资源
var solidColor = App.Current.FindResource("SolidColor");
var style = App.Current.FindResource("DefaultButtonStyle");
}
}
}动画基础
MainWindow.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;

using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfDay03
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
//this.Resources["SolidColor"] = new SolidColorBrush(Colors.Blue);
//var solidColor = App.Current.FindResource("SolidColor");
//var style = App.Current.FindResource("DefaultButtonStyle");
//创建一个双精度动画
DoubleAnimation animation = new DoubleAnimation();
animation.By = -30;
//animation.From = btn.Width; //设置动画的初始值
//animation.To = btn.Width - 30; //设置动画的结束值
animation.Duration = TimeSpan.FromSeconds(1); //设置动画的持续时间
animation.AutoReverse = true; //是否往返执行
animation.RepeatBehavior = new RepeatBehavior(3); //RepeatBehavior.Forever; 执行周期
animation.Completed += Animation_Completed;
btn.BeginAnimation(Button.WidthProperty, animation);
}
private void Animation_Completed(object sender, EventArgs e)
{
btn.Content = "动画已完成";
}
}
}MainWindow.xaml
