有时,我们需在我们的程序中模拟鼠标的移动、点击等动作。——比如,一个再现用户操作的宏,或者一个演示操作方法的Demo程序。那么,我们在.Net中如何实现呢?.Net并没有提供改变鼠标指针位置、模拟点击操作的函数;但是Windows API提供了。其中一个是:
        [DllImport("user32.dll")]        static extern bool SetCursorPos(int X, int Y); 
该函数可以改变鼠标指针的位置。其中X,Y是相对于屏幕左上角的绝对位置。另一个函数是:
        [DllImport("user32.dll")]        static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);
这个函数不仅可以设置鼠标指针绝对的位置,而且可以以相对坐标来设置。另外,该函数还可以模拟鼠标左右键点击、鼠标滚轮操作等。其中的MouseEventFlag是一个基于uint类型的枚举,定义如下:
        [Flags]        enum MouseEventFlag : uint        {            Move        = 0x0001,            LeftDown    = 0x0002,            LeftUp      = 0x0004,            RightDown   = 0x0008,            RightUp     = 0x0010,            MiddleDown = 0x0020,            MiddleUp    = 0x0040,            XDown       = 0x0080,            XUp         = 0x0100,            Wheel       = 0x0800,            VirtualDesk = 0x4000,            Absolute    = 0x8000        }
关于这两个函数的详细说明,可以查看MSDN Library或者Windows的Platform SDK文档。下面的演示程序(完整版源代码,VS.Net 2005/C#)演示了使用上面的函数,控制鼠标移动到任务栏并点击“开始”按钮的方法。(该程序使用了FindWindowEx等API函数来查找任务栏及开始菜单)
