    class Program
    {
        [StructLayout(LayoutKind.Sequential)]
        public struct tagRECT
        {
 
            /// LONG->int
            public int left;
 
            /// LONG->int
            public int top;
 
            /// LONG->int
            public int right;
 
            /// LONG->int
            public int bottom;
        }
 
        /// Return Type: BOOL->int
        ///lpRect: RECT*
        [DllImport("user32.dll", EntryPoint = "ClipCursor")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool ClipCursor([In] IntPtr lpRect);
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            tagRECT rect = new tagRECT() { left = 0, top = 0, right = 1, bottom = 1 };
            var p = Marshal.AllocHGlobal(Marshal.SizeOf(rect));
            Marshal.StructureToPtr(rect, p, false);
            ClipCursor(p);//锁定
 
            ClipCursor(IntPtr.Zero);//解锁
 
        }
    }
    //如果需要，还可以隐藏指针
