自己寫的關機、註銷、重啓小程序

無聊的時候自己寫了個關於關機、註銷、重啓的程序..

主要的界面如下：

 

主要的原理是調用計算機裏面的：cmd.exe 這個

用法如下：

下面是代碼部分：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Text.RegularExpressions;

    {
        private string regStr="^[0-9]*$";
        private int second = 0;

        public DoWork()
        {
            InitializeComponent();
            this.timer1.Stop();
        }

                {

                    return;
                }

                this.btnConfirm.Text = "中 止";

                second = Convert.ToInt32(this.txtTime.Text.Trim()) * 60;
                this.timer1.Start();
            }
            else
