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。

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;
        }
    }
}
