程序自我重啓 --- 實用方法

1.問題或需求描述：
程序自我重啓，或在局域網環境下更新重啓。

2.解決方法或原理：
可建立前臺或後臺 cmd進程，實現程序更新重啓。

C#代碼：

...
using System.Diagnostics;
using System.IO;
...

private void Restart()
{
    //得到當前程序信息
    Process cur = Process.GetCurrentProcess();
    FileInfo fi = new FileInfo(cur.MainModule.FileName);

    try
    {
        Process subPro = new Process();
        subPro.StartInfo.UseShellExecute = true;
        subPro.StartInfo.FileName = "cmd";
        subPro.StartInfo.Arguments = " /q /c echo 請勿中斷,正在重啓程序... & ping -n 3 127.1 1>nul 2>nul & taskkill /pid "
            + cur.Id + " 1>nul 2>nul & start \"\" /max \"" 
            + cur.MainModule.FileName + "\"";
        subPro.StartInfo.CreateNoWindow = false;
        subPro.Start();
    }
    catch
    {
            //Add your code
    }
    finally
    {
        Close();
    }
}

private void Update()
{
    try
    {
        //網絡程序位置定義
        const string sNetExePath = @"\\192.168.158.25\setup\Test\test.exe";

        //得到當前程序信息
        Process cur = Process.GetCurrentProcess();
        FileInfo fi = new FileInfo(cur.MainModule.FileName);

        //得到網絡位置程序信息
        FileInfo fi2 = new FileInfo(sNetExePath);

        //比較文件修改時間戳，若是網絡文件較新則更新本地程序並重啓
        if (DateTime.Compare(fi2.LastWriteTime, fi.LastWriteTime) > 0)
        {
            try
            {
                Process subPro = new Process();
                subPro.StartInfo.UseShellExecute = true;
                subPro.StartInfo.FileName = "cmd";
                subPro.StartInfo.Arguments = " /q /c echo 請勿中斷,正在更新程序... & ping -n 3 127.1 1>nul 2>nul & taskkill /pid " 
                    + cur.Id + " 1>nul 2>nul & copy /y \"" 
                    + sNetExePath + "\" \"" 
                    + cur.MainModule.FileName 
                    + "\" 1>nul 2>nul && start \"\" /max \"" 
                    + cur.MainModule.FileName + "\"";
                subPro.StartInfo.CreateNoWindow = false;
                subPro.Start();
            }
            catch
            {

            }
            finally
            {
                Close();
            }
        }
    }
    catch
    {

    }
}
