C#外掛QQ找茬輔助源碼，早期開發

這是一款幾年前開發的工具，當年做爲一民IT純屌，爲了當年本身心目中的一位女神熬夜開發完成。女神使用後找茬等級瞬間從眼明手快升級爲三隻眼。。。每次看到這個就會想起那段屌絲與女神的回憶。今天特意把代碼更新了一下，支持最新版的《你們來找茬》。下面上運行的截圖，源碼在本文最後：（對不起了，與我對戰的那位玩家）

這個工具的主要運行流程很簡單：遊戲截圖-》比較圖片-》標記圖片不一樣點
記得當時處理程序截圖和比較圖片的時候比較麻煩，下面是截圖的處理類ScreenCapture：

  1 /// <summary>   
  2 /// 提供全屏和指定窗口的截圖 以及保存爲文件的類   
  3 /// </summary>
