應用程序凍結在「StandardOutput.ReadLine（）」上。

Question

嘗試調用「StandardOutput.ReadLine（）」時應用程序掛起。

代碼：

ProcessStartInfo startInfo = new ProcessStartInfo("c:\\windows\\system32\\myTesting.exe"); 
      String s = " "; 

      startInfo.WindowStyle = ProcessWindowStyle.Hidden; 
      startInfo.CreateNoWindow = true; 
      startInfo.RedirectStandardInput = true; 
      startInfo.RedirectStandardOutput = true; 
      startInfo.UseShellExecute = false; 
      Process p = Process.Start(startInfo); 
      p.StandardInput.WriteLine("list volume\n"); 
      String f = ""; 

      while (!p.StandardOutput.EndOfStream) 
       { 
        s = p.StandardOutput.ReadLine(); 
       } 

「死鎖例外」 誤差有時會發生，但並非總是如此。

perhabs the wihle is the problem。剛剛嘗試這一點：

// Create the child process. 
Process p = new Process(); 

// Redirect the output stream of the child process. 
p.StartInfo.UseShellExecute = false; 
p.StartInfo.RedirectStandardOutput = true; 

//setting the application path 
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. 
// Read the output stream first and then wait. 
string output = p.StandardOutput.ReadToEnd(); 
p.WaitForExit();
