的Visual C＃GUI停止响应时process.WaitForExit（）;用来 [英] Visual C# GUI stops responding when process.WaitForExit(); is used

问题描述

我创建使用Visual C＃2005（.NET框架2）一个GUI应用程序。我用下面的代码来启动一个进程：

I am creating a GUI application using Visual C# 2005 (net framework 2). I use the following code to start a process:

Process process = new Process();
process.StartInfo = new ProcessStartInfo("app.exe");
process.StartInfo.WorkingDirectory = "";
process.StartInfo.Arguments = "some arguments";
process.Start();
process.WaitForExit();

我想我的应用程序要等到过程结束，所以我用WaitForExit。但是，GUI窗口，同时APP.EXE运行冻结。我希望它作出反应（如按下取消按钮），但我不希望代码继续，因为有另一个进程比后启动。在此先感谢！

I want my application to wait until this process is finished, so I used WaitForExit. But the GUI Windows freezes while app.exe is running. I want it to respond (e.g. press a cancel button), but I don't want the code to continue, because there is another process to start after than. Thanks in advance!

推荐答案

您可以捕捉的退出Process类的事件：

void someMethod()
{
    //...possibly more code here
    Process process = new Process();
    process.StartInfo = new ProcessStartInfo("app.exe");
    process.StartInfo.WorkingDirectory = "";
    process.StartInfo.Arguments = "some arguments";
    process.Exited += new EventHandler(ProcessExited);
    process.Start();
}

void ProcessExited(object sender, System.EventArgs e)
{
  //Handle process exit here
}
