检测单个 Windows 进程退出事件 C#

Question

好的，我得到了另一个，现在我正在处理一个按钮，在代码中称为 installbtn。

现在我的代码中有。

private void installbtn_Click(object sender, EventArgs e)
        {
// Access the internal exe resource pcc - the pcc is Path Copy Copy, which i am using as a
// requirement to use this software
   byte[] pccFile = Properties.Resources.pcc;  

// The resource pcc.exe as a binary called pcc which is then used as a byte called pccFile  
   string pccExe = Path.Combine(Path.GetTempPath(), "pcc.exe");  
// The Executable and its filename + Extenstion
   using (FileStream exeFile = new FileStream(pccExe, FileMode.Create))
   exeFile.Write(pccFile, 0, pccFile.Length);
// Write the file to users temp dir
   Process.Start(pccExe);

// Start the Installer
   installbtn.Text = "Installing...";
   StatusLabel1.Text = "Installing PCC Now...";
// Indicate on the form, the current process status.


// Here i want the application to check if pccExe has closed
// after the user has installed the component and its process "pcc.exe" exits
   MessageBox.Show("Module Installed /r/nPlease Start the Application", "Application Module Installed");
   installbtn.Text = "Restart Now!";
   StatusLabel1.Text = "Please Restart the Application";
// and if it has then show a message box and reflect in the form
// i want it to quit and restart the application after the message box is closed
}

现在当安装程序完成时，我希望能够检测到安装程序在安装后何时关闭("pcc.exe")，然后重新加载应用程序。不确定它是否可能，但我将不胜感激。

谢谢肖恩。

Answer 1

你可以使用Process.WaitForExit()

WaitForExit() 重载用于使当前线程等待 直到相关进程终止。该方法指示 进程组件等待进程的无限时间 和要退出的事件处理程序

Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
process.StartInfo = startInfo;

startInfo.FileName = exeToRun;    
process.Start();
process.WaitForExit();

Answer 2

Start 返回一个Process 对象，您可以在该对象上等待（或启动等待的线程等）。
