在C#中如何模拟鼠标键盘操作

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: }
