c# - 程序运行C#时读取控制台输出

我有一个要运行外部程序的C＃程序，并且在该程序运行时，它需要读取控制台输出并将其以JSON格式发送到服务器。这就是我的想法。能行吗

ProcessStartInfo psi = new ProcessStartInfo("app.exe");
psi.RedirectStandardOutput = true;
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.UseShellExecute = false;
Process app = Process.Start(psi);

while (true)// what do I loop on?
{
    string line = "{ \"message\": \"" + app.StandardOutput.ReadLine() + "\" }";

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url + "/results/:" + runId + "/logs");
    request.ContentType = "text/json";
    request.Method = "POST";
    using (TextWriter tw = new StreamWriter(request.GetRequestStream()))
    {
        tw.WriteLine(line);
    }
}

最佳答案

最好使用Process类的Process.OutputDataReceived事件，以免阻止程序执行，并且不要在while(true)循环中运行代码！

如果主程序只需要站立等待该过程退出，就可以

Process app = Process.Start(psi);
//  read code, subscription to event described above,
// and processing it inside event handler

app.WaitForExit();
