#======================简化一下

C# 重新启动程序(并非重启计算机)

private void Restart()         {             Thread thtmp = new Thread(new ParameterizedThreadStart(run));             object appName = Application.ExecutablePath;             Thread.Sleep(2000);             thtmp.Start(appName);         }         private void run(Object obj)         {             Process ps = new Process();             ps.StartInfo.FileName = obj.ToString();             ps.Start();         }         ///         /// 设置         ///         ///         ///         private void btnConfig_Click(object sender, EventArgs e)         {             frmHikClientConfig frm = new frmHikClientConfig();             if (frm.ShowDialog() == DialogResult.OK)             {                 Application.ExitThread();                 Restart();             }         }

//============或者（下面的没测试）

clossing事件中，用Process.Start启动一下自己就可以。  
   
   
  在主窗体的closing事件中，加入如下代码：  
   
  if   (   MessageBox.Show("要重新启动嘛？","提示",   MessageBoxButtons.YesNoCancel,  
  MessageBoxIcon.Question)   ==   DialogResult.Yes)  
   
  System.Diagnostics.Process.Start(System.Reflection.Assembly.GetExecutingAssembly().Location);
