C#启动外部应用程序，并关闭自己(急)

还有一种是shell的exec方式     [DllImport("shell32.dll")]

public     static     extern     int     ShellExecute(IntPtr     hwnd,StringBuilder     lpszOp,StringBuilder     lpszFile,StringBuilder     lpszParams,StringBuilder     lpszDir,int     FsShowCmd);

调用：
      ShellExecute(IntPtr.Zero,new     StringBuilder("Open"),new     StringBuilder("notepad"),new     StringBuilder(""),new     StringBuilder(@"C:"),1);

另：怎样在C#程式中获取到当前应用程式的名称（如：当前运行的是PMC.exe，应知道这个名称）

退出当前的程序
Application.ExitThread();

其实LZ要做的是升级程序,监视程序监视网络新版本,如果有,则关闭主程序 kill掉
然后下载新的文件覆盖老的文件,覆盖后再start它监视程序完全可以不去关闭而一直监视

        private void button1_Click(object sender, EventArgs e)
        {
            //string mFilePath = Application.StartupPath + "\\SysUpdate.exe";
            string mFilePath = "d:\\2.exe";          System.Diagnostics.Process pc=  Process.Start(mFilePath);
          while (pc.Handle == IntPtr.Zero)
          {
              Application.DoEvents();
          }
          this.Close();        }

晕，我这怎么没有错        private void button2_Click(object sender, EventArgs e)
        {
            Process p = Process.Start("WindowsFormsApplication7.exe");
            this.Close();
            //Application.Exit();
        }

解耦合的自动更新核心代码。自己看，不解释。[STAThread]

            if (!flag)
            {
                MessageBox.Show("已经存在系统，无法再启动！");
            }
