上一篇讲了在自动化测试中如果控件不能识别，我们最后的办法是模拟鼠标键盘，这一篇就讲如何来做。

首先我先讲在C#中怎么做，至于在C++或者脚本中怎么做，留在后边来讲

对C#来说，键盘的模拟比较简单，在.Net Framework中System.Windows.Forms.SendKeys这个类

鼠标呢，看下边代码：

   1: [DllImport("user32")]

   2: public static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);

   3: 

   4: [Flags]

   5: public enum MouseEventFlags

   6: {

   7:     Move = 0x0001,

   8:     LeftDown = 0x0002,

   9:     LeftUp = 0x0004,

  10:     RightDown = 0x0008,

  11:     RightUp = 0x0010,

  12:     MiddleDown = 0x0020,

  13:     MiddleUp = 0x0040,

  14:     Wheel = 0x0800,

  15:     Absolute = 0x8000

  16: }

  17: 

  18: void PixelsToAbsCoors(double x, double y, ref double xOut, ref double yOut)

  19: {

  20:     //points are based on current screen size setting   

  21:     xOut = x * 65536 / Screen.PrimaryScreen.Bounds.Width + 0.5;

  22:     yOut = y * 65536 / Screen.PrimaryScreen.Bounds.Height + 0.5;

  23: }

  24: public void Move(double x, double y)

  25: {

  26:     PixelsToAbsCoors(x, y, ref x, ref y);

  27:     mouse_event((int)(MouseEventFlags.Move | MouseEventFlags.Absolute), (int)x, (int)y, 0, 0);

  28: }

  29: public void Click(double x, double y)

  30: {

  31:     Move(x, y);

  32:     PixelsToAbsCoors(x, y, ref x, ref y);

  33:     mouse_event((int)(MouseEventFlags.LeftDown | MouseEventFlags.Absolute), (int)x, (int)y, 0, 0);

  34:     mouse_event((int)(MouseEventFlags.LeftUp | MouseEventFlags.Absolute), (int)x, (int)y, 0, 0);

  35: }
