因为是做显示程序，故需要控制任务栏与开始菜单的显示与隐藏，这样就美观些。不啰嗦。直接上代码：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Runtime.InteropServices;

using System.Drawing;

using System.Management;

using System.Collections;

using Microsoft.Win32;

namespace DssDisplay {

    class ClsWin32 {

        [DllImport("user32.dll")]

        public static extern bool GetCursorPos(ref Point lpPoint);

        [DllImport("user32.dll", EntryPoint = "FindWindowEx", SetLastError = true)]

        public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);

        [DllImport("user32.dll", EntryPoint = "ShowWindow", SetLastError = true)]

        public static extern bool ShowWindow(IntPtr hWnd, uint nCmdShow);

        public static Point GetCursorPos() {

            Point point = new Point();

            GetCursorPos(ref point);

            return point;

        }

        public static void HideTask(bool isHide) {

            try {

                IntPtr trayHwnd = FindWindowEx(IntPtr.Zero, IntPtr.Zero, "Shell_TrayWnd", null);

                IntPtr hStar = FindWindowEx(IntPtr.Zero, IntPtr.Zero, "Button", null);

                if (isHide) {

                    ShowWindow(trayHwnd, 0);

                    ShowWindow(hStar, 0);

                }

                else

                {

                    ShowWindow(trayHwnd, 1);

                    ShowWindow(hStar, 1);

                }

            } catch { }

        }

}

}
