C# Form自定义光标的简单实现

下面是完整的例子，可以通过命令行编译即可看到效果。

using system;
using system.drawing;
using system.windows.forms;
using system.runtime.interopservices;
using system.reflection;

namespace colorcursor
{
 /// <summary>
 /// 本例子的作用： 在.net中实现自定义光标。
 /// </summary>
    public class form1 : system.windows.forms.form
    {
        [dllimport("user32.dll")]
        public static extern intptr loadcursorfromfile( string filename );

        [dllimport("user32.dll")]
        public static extern intptr setcursor( intptr cursorhandle );

        [dllimport("user32.dll")]
        public static extern uint destroycursor( intptr cursorhandle );

 
        [stathread]
        static void main()
        {
            application.run(new form1());
        }

        public form1()
        {
            cursor mycursor = new cursor(cursor.current.handle);
            intptr colorcursorhandle = 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,
            new object [] { colorcursorhandle } );
            this.cursor = mycursor;
        }
    }
}
