using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using System.Runtime.InteropServices;
using System.Windows.Forms;


namespace GameLink.GameClass
{
    /// <summary>
    /// 自定义鼠标样式
    /// 可以是彩色 动画==
    /// </summary>
    class MouseStyle
    {
        [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 MouseStyle()
        {
        }
        public Cursor MyMouseStyle(string filename)
        {
            Cursor myCursor = new Cursor(Cursor.Current.Handle);
            IntPtr colorCursorHandle = LoadCursorFromFile(filename);
            myCursor.GetType().InvokeMember("handle", BindingFlags.Public |
                BindingFlags.NonPublic | BindingFlags.Instance |
                BindingFlags.SetField, null, myCursor, new object[] { colorCursorHandle });
            return myCursor;
        }
    }
}


给你一个类你自己调用哟
