C# Form实现自定义光标

WinForm代码如下：

 using System;
 using System.Reflection;
 using System.Runtime.InteropServices;
 using System.Windows.Forms;

 namespace KeleyiColorCursor
 {
 public partial class CursorForm : 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);

 public CursorForm()
 {
 InitializeComponent();
 Cursor myCursor = new Cursor(Cursor.Current.Handle);
 string m_cursorFile = @"D:\keleyi\pen_r.cur";

 //pen_r.cur文件下载地址：
 //http://down.keleyi.com/files/cursors/pen_r.cur

 //或者设为动态光标
 // m_cursorFile = @"D:\keleyi\dinosau2.ani";
 //下载地址： http://down.keleyi.com/files/cursors/dinosau2.ani

 IntPtr colorCursorHandle = LoadCursorFromFile(m_cursorFile);

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

运行后，如果把光标移入窗体，光标消失了，那是因为没有下载光标文件到特定文件夹。
