C#外挂QQ找茬辅助源码，早期开发
这是一款几年前开发的工具，当年作为一民IT纯屌，为了当年自己心目中的一位女神熬夜开发完成。女神使用后找茬等级瞬间从眼明手快升级为三只眼。。。每次看到这个就会想起那段屌丝与女神的回忆。今天特地把代码更新了一下，支持最新版的《大家来找茬》。下面上运行的截图，源码在本文最后：（对不起了，与我对战的那位玩家）
这个工具的主要运行流程很简单：游戏截图-》比较图片-》标记图片不同点
记得当时处理程序截图和比较图片的时候比较麻烦，下面是截图的处理类ScreenCapture：
1 /// <summary> 2 /// 提供全屏和指定窗口的截图 以及保存为文件的类 3 /// </summary> 4 public class ScreenCapture 5 { 6 /// <summary> 7 /// 全屏截图 8 /// </summary> 9 /// <returns></returns> 10 public Image CaptureScreen() 11 { 12 return CaptureWindow(User32.GetDesktopWindow()); 13 } 14 /// <summary> 15 /// 指定窗口截图 16 /// </summary> 17 /// <param name="handle">窗口句柄.
