下面是完整的例子，可以通过命令行编译即可看到效果。
复制代码 代码如下:
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;
}
}
}
