Cursor

如果要用彩色Cursor的话，需要把你的Cursor保存成一个BMP图片，然后调API来做

C# codepublic partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e) {
            Stream str = GetType().Assembly.GetManifestResourceStream("WindowsApplication1.Cursor.bmp");
            Bitmap bmp = new Bitmap(str);
            this.Cursor = CreateCursor(bmp, 3, 3);
        }

        public static Cursor CreateCursor(Bitmap bmp, int xHotSpot, int yHotSpot) {
            IconInfo tmp = new IconInfo();
            GetIconInfo(bmp.GetHicon(), ref tmp);
            tmp.xHotspot = xHotSpot;
            tmp.yHotspot = yHotSpot;
            tmp.fIcon = false;
            return new Cursor(CreateIconIndirect(ref tmp));
        }

        public struct IconInfo {
            public bool fIcon;
            public int xHotspot;
            public int yHotspot;
            public IntPtr hbmMask;
            public IntPtr hbmColor;
        }

        [DllImport("user32.dll")]
        public static extern IntPtr CreateIconIndirect(ref IconInfo icon);

        [DllImport("user32.dll")]
        [return : MarshalAs(UnmanagedType.Bool)]
        public static extern bool GetIconInfo(IntPtr hIcon, ref IconInfo pIconInfo);
    }
