本文演示了如何在C#中使用命令行代码：

string command = System.Configuration.ConfigurationSettings.AppSettings["Command"];//ping www.baidu.com
try
{
      	Process p = new Process();
        p.StartInfo.FileName = "cmd.exe";
        p.StartInfo.Arguments = "/c " + command;
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardInput = true;
        p.StartInfo.RedirectStandardOutput = true;
        p.StartInfo.CreateNoWindow = true;
        p.Start();
        outputMsg = p.StandardOutput.ReadToEnd();
        p.Close();
        if (outputMsg.Contains("Reply"))
        {
        isComputerOn = "SUCCESS";
         return true;
        }
        else
        {
        isComputerOn = "ERROR";
        return false;
        }
        }
       catch (Exception ex)
       {
       return false;
       }
}
