使用C#进行Python脚本输出重定向 [英] Python script output redirection using C#

问题描述

这个问题似乎是重复的，我已经尝试了所有建议的解决方案，但是徒然，我想使用此代码重定向python脚本输出:

this question could seem as duplicate, i have tried all the suggested solution but in vain , i wanna redirect python script output using this code :

    System.Diagnostics.Process proc = new System.Diagnostics.Process();
    proc.StartInfo.FileName = "python.exe";
    proc.StartInfo.Arguments = Application.StartupPath.Replace("\\bin\\Debug", "") + "\\scripts\\test.py";
    proc.OutputDataReceived += OutputDataReceived;
    proc.ErrorDataReceived += ErrorDataReceived;

    proc.StartInfo.RedirectStandardOutput = true;
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.CreateNoWindow = true;
    proc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; 

    proc.Start();
    //proc.WaitForExit();

    StringBuilder q = new StringBuilder();
    while (!proc.HasExited)
    {
        q.Append(proc.StandardOutput.ReadToEnd());
    }
    string r = q.ToString();
    r = proc.StandardOutput.ReadToEnd();
    MessageBox.Show(r);
}
private void OutputDataReceived(object sender, DataReceivedEventArgs args)
{
    //textOutput.Text += args.Data;
    MessageBox.Show(args.Data);
}

python脚本包含 print"hello test" ，但我尝试取消缓冲输出却徒劳.

the python script contains print "hello test" i tried unbuffering output but vainly.

请帮忙.

我正在使用VS 2010 .NET 4.0，Python 2.7，winXP sp3.

推荐答案

尝试创建StreamReader实例而不是StringBuilder.这段代码对我来说很好:

Try to create a StreamReader instance instead of StringBuilder. this code works for me just fine:

 System.Diagnostics.Process proc = new System.Diagnostics.Process();
        proc.StartInfo.FileName = "ping.exe";
        proc.StartInfo.Arguments = "8.8.8.8";


        proc.StartInfo.RedirectStandardOutput = true;
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.CreateNoWindow = true;
        proc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

        proc.Start();
       StreamReader q = proc.StandardOutput;
       while (!proc.HasExited)
         Console.WriteLine(q.ReadLine());

        Console.ReadKey();
