获取鼠标的坐标

【在窗体上获取相对于屏幕的坐标：】
方法1：
	public class Win32
    {
        [StructLayout(LayoutKind.Sequential)]
        public struct POINT
        {
            public int X;
            public int Y;

            public POINT(int x, int y)
            {
                this.X = x;
                this.Y = y;
            }
        }

        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        public static extern bool GetCursorPos(out POINT pt);
    }

方法2：
	Mouse.GetPosition(this)

方法3：
	在鼠标mousemove事件中	e.GetPosition(this)

【获取全局鼠标坐标】
