求EXE相互调用的写法

Question

例如a.exe上有个按钮，按下后，调用b.exeb.exe上一按钮按下，关闭a.exe,更新a.exe
然后重新启动a.exe,并且关闭本身即b.exe不知道如何写，也使用了 private void Restart()
    {
        Thread thtmp = new Thread(new ParameterizedThreadStart(run));
        object appName = Application.StartupPath+"\\b.EXE" ;
        Thread.Sleep(2000);
        thtmp.Start(appName);    }    private void run(Object obj)
    {
        Process ps = new Process();
        ps.StartInfo.FileName = obj.ToString();
        ps.Start();
    }可是依然行不通，忘前辈能否写个例子，谢谢

Answer 1

a按钮代码
System.Diagnostics.Process.Start(Application.StartPath + "\\b.exe");b按钮代码
查找a进程，kill掉a
foreach (System.Diagnostics.Process p in System.Diagnostics.Process.GetProcesses())
            {
                if (p.ProcessName == "a")
                {
                    p.Kill();
                    p.WaitForExit();
                    break;
                }
            }
然后更新a，
再启动a
System.Diagnostics.Process.Start(Application.StartPath + "\\b.exe");
最后b关闭，this.Close();
