C#Form自定义光标的简单实现

           IntPtrcolorCursorHandle=LoadCursorFromFile(@"C:WINNTCursorsdinosau2.ani");   
           //dinosau2.ani为windows自带的光标：

           myCursor.GetType().InvokeMember("handle",BindingFlags.Public|
           BindingFlags.NonPublic|BindingFlags.Instance|
           BindingFlags.SetField,null,myCursor,
           newobject[]{colorCursorHandle});
           this.Cursor=myCursor;
