【工具】C#游戏防沉迷小工具

背景介绍

嘿，各位小伙伴！今天想跟大家唠唠我为啥要搞这么个防沉迷小工具。
咱都清楚，现在这游戏啊，玩起来那叫一个带劲，但时间一长，不仅眼睛累，心也跟着累。有些游戏，规则定得挺有意思：要是玩超过 15 分钟，你就可以秒退了，系统不会给你什么惩罚。这不，我就寻思着，要是有个东西能帮咱盯着游戏开始的时间，到时候提醒咱一声，那该多好啊！我可以根据当前局势判断要不要退出，要是碰到开挂的、花钱的，那果断推出，不能苦了自己舒服了别人。
于是，我就琢磨着做这么个防沉迷小工具。它的功能说白了就是：在后台悄悄看着游戏进程，一旦快到那个关键的 15 分钟（或者你可以自己定别的时长），就给你来个提醒，比如播放个声音，或者用其他方式。这样，咱就能根据当时的游戏情况，决定是赶紧退出 “保全自己”，还是再坚持一会儿。
而且啊，这小工具还很灵活，支持各种配置。你可以根据自己的喜好，调整提醒的时间、方式啥的，想怎么来就怎么来。不管你是想避开那些开挂的，还是不想被诱导花冤枉钱，有了它，都能帮你更果断地做出选择，不至于让自己玩得太累，让别人占了便宜。
总之，这防沉迷小助手就是咱在游戏世界里的一位贴心 “小管家”，帮咱把握好分寸，让咱玩得开心又不 “上头”。

一、需求设计目标

在游戏场景中，许多防沉迷系统采用强制退出机制。本工具旨在实现柔性提醒机制，通过声音、弹窗、窗口抖动等方式提醒用户，同时满足以下工程目标：

可配置化：支持配置进程匹配规则、提醒策略等参数
扩展性：可灵活添加新的提醒方式
健壮性：避免资源泄漏，处理进程访问异常
低侵入性：不修改目标进程内存或行为

效果如下：
效果图

二、架构设计

采用分层架构：

配置层：处理XML配置加载
监控层：实现进程状态检测
策略层：多种提醒策略实现
UI层：提供配置界面和状态显示

三、关键模块实现

3.1 配置管理模块

使用.NET ConfigurationSection实现自定义配置：

public class ProcessMonitorSection : ConfigurationSection
{
    [ConfigurationProperty("ProcessItems")]
    public ProcessItemCollection ProcessItems => 
        (ProcessItemCollection)this["ProcessItems"];
}

优势：

配置热加载能力
强类型配置访问
配置验证机制

3.2 进程监控引擎

核心监控流程：

关键技术点：

通配符转正则表达式

private Regex ConvertWildcardToRegex(string pattern)
{
    return new Regex("^" + 
        Regex.Escape(pattern)
            .Replace("\\*", ".*")
            .Replace("\\?", ".") + "$", 
        RegexOptions.IgnoreCase);
}

进程生命周期管理
异常处理机制

3.3 策略模式实现提醒

策略接口定义：

public interface IAlertStrategy
{
    Task ExecuteAsync(AlertContext context);
}

具体策略示例（窗口抖动）：

public class WindowShakeStrategy : IAlertStrategy
{
    public async Task ExecuteAsync(AlertContext context)
    {
        await Task.Run(() => 
        {
            for (int i = 0; i < 3; i++) {
                NativeMethods.ShakeWindow(_windowHandle);
                Thread.Sleep(200);
            }
        });
    }
}

策略组合配置示例：

<add processNamePattern="notepad++" 
     addictionTime="300"
     soundAlert="Alarm01.wav"
     messageBoxText="该休息了！"
     showMessageBox="true"/>

四、工程实践亮点

4.1 资源管理

实现IDisposable接口
使用using语句确保资源释放
定时器生命周期控制

4.2 并发控制

锁机制保护共享资源

lock (_lock)
{
    // 访问_monitorItems
}

异步策略执行避免UI阻塞

4.3 可观测性

日志跟踪系统状态
异常捕获与处理

catch (Exception ex) when (ex is Win32Exception || ex is InvalidOperationException)
{
    // 处理进程访问异常
}

五、使用与扩展

5.1 配置示例

<ProcessItems>
    <add processNamePattern="game*.exe" 
         addictionTime="900"
         soundAlert="alert.wav"
         messageBoxText="游戏时间已达15分钟"
         showMessageBox="true"/>
</ProcessItems>

5.2 扩展新策略

实现IAlertStrategy接口
在配置中添加新策略参数
在工厂方法中创建策略实例

示例（邮件提醒策略）：

public class EmailAlertStrategy : IAlertStrategy
{
    public Task ExecuteAsync(AlertContext context)
    {
        return Task.Run(() => 
        {
            // 发送邮件逻辑
        });
    }
}
