如何打印出子进程使用C＃打印的值？

正如本文所述，我可以使用Python的subprocess.Popen（）函数打印出运行ruby代码的值。

import subprocess import sys cmd = ["ruby", "/Users/smcho/Desktop/testit.rb"] p = subprocess.Popen(cmd, stdout=subprocess.PIPE) for line in iter(p.stdout.readline, ''): print line, sys.stdout.flush() p.wait() 

我怎么能用C＃做同样的事情？ 如何打印子进程打印出来的值？

Answer 1

在生成子进程时需要重定向stdout; MSDN有一个完整的例子： http ： //msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandardoutput.aspx

（来自MSDN）：

  // Start the child process. Process p = new Process(); // Redirect the output stream of the child process. p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "Write500Lines.exe"; p.Start(); // Do not wait for the child process to exit before // reading to the end of its redirected stream. // p.WaitForExit(); // Read the output stream first and then wait. string output = p.StandardOutput.ReadToEnd(); p.WaitForExit();

 ProcessStartInfo psi = new ProcessStartInfo("ruby", "/Users/smcho/Desktop/testit.rb"); psi.RedirectStandardOuput = true;W Process proc = new Process(psi); proc.Start(); StreamReader stdout = proc.StandardOutput; string line; while ((line = stdout.ReadLine()) != null) Console.WriteLine(line);
