C＃执行cmd命令不起作用

Question

任何人都可以建议为什么下面的代码不返回系统日期？

ProcessStartInfo cmdInfo = new ProcessStartInfo("cmd.exe", "net time \\192.168.221.1"); 
      cmdInfo.CreateNoWindow = true; 
      cmdInfo.RedirectStandardOutput = true; 
      cmdInfo.RedirectStandardError = true; 
      cmdInfo.UseShellExecute = false; 

      Process cmd = new Process(); 
      cmd.StartInfo = cmdInfo; 
      var output = new StringBuilder(); 
      var error = new StringBuilder(); 

      cmd.OutputDataReceived += (o, e) => output.Append(e.Data); 
      cmd.ErrorDataReceived += (o, e) => error.Append(e.Data); 

      cmd.Start(); 
      cmd.BeginOutputReadLine(); 
      cmd.BeginErrorReadLine(); 
      cmd.WaitForExit(); 
      cmd.Close(); 
      var s = output; 
      var d = error; 

输出是

{Microsoft Windows [Version 6.1.7601]Copyright (c) 2009 Microsoft Corporation. All rights reserved.D:\TEST\TEST\bin\Debug>}

尝试用这种

ProcessStartInfo cmdInfo = new ProcessStartInfo("cmd.exe", "/C net time \\\\192.168.221.1"); 

您需要添加/ C开关赶CMD外壳中运行命令的输出。
另外，反斜杠应加倍或使用字符串逐字前缀@
