ShutDown C＃項目

Question

我目前正在編寫一個程序，應該按下按鈕時關閉/重新啓動，但是當我按下關機或重新啓動按鈕時，操作立即完成而無需等待（datetimepicker）中指定的時間。

這裏是我的代碼：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace WindowsFormsApplication8 
{ 
    public partial class Form2 : Form 
    { 
     private DateTime tm; 
     public Form2() 
     { 
      InitializeComponent(); 
     } 
     private void button1_Click(object sender, EventArgs e) 
     { 
      if (DateTime.Now.CompareTo(tm) > 0) 
      { 
       Sti(); 
       System.Diagnostics.Process.Start("shutdown", "/s"); 
      } 
      else 
      { 
       MessageBox.Show("your computer will shutdown shortly ...."); 
      } 

     } 
     private void Sti() 
     { 
      if (DateTime.Now.TimeOfDay.CompareTo(tm.TimeOfDay) > 0) 
      { 
       tm = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day + 1, tm.Hour, tm.Minute, tm.Second); 
      } 
      else 
      { 
       tm = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, tm.Hour, tm.Minute, tm.Second); 
      } 

     } 

     private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e) 
     { 
      this.Show(); 
     } 

     private void notifyIcon1_MouseClick(object sender, MouseEventArgs e) 
     { 

     } 

     private void button2_Click(object sender, EventArgs e) 
     { 
      if (DateTime.Now.CompareTo(tm) >= 0) 
      { 
       Sti(); 
       System.Diagnostics.Process.Start("shutdown", "/r"); 
      } 
      else 
      { 
       MessageBox.Show("your computer will shutdown shortly ...."); 
      } 


     } 
    } 
}

使用-t開關shutdown指定一個等待期

shutdown {-r|-s} -t xxx 

其中xxx是秒的等待的秒數。
