在.NET中实现彩色光标，动画光标和自定义光标[引自孟子前辈作品]

下面是完整的例子，可以通过命令行编译即可看到效果。

Test.cs

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中实现彩色光标，动画光标和自定义光标。
/// </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()
  {
  this.Text = "欢迎光临【孟宪会之精彩世界】:http://dotnet.aspx.cc/";
  Cursor myCursor = new Cursor(Cursor.Current.Handle);
  //dinosau2.ani为windows自带的光标：
  IntPtr colorCursorHandle = LoadCursorFromFile(@"C:\WINNT\Cursors\dinosau2.ani" );
  myCursor.GetType().InvokeMember("handle",BindingFlags.Public |
   BindingFlags.NonPublic | BindingFlags.Instance |
   BindingFlags.SetField,null,myCursor,
   new object [] { colorCursorHandle } );
  this.Cursor = myCursor;
  }
}
}
