如何解析从C＃命令行输出？ [英] How to parse command line output from c#?

问题描述

我要执行从C＃应用程序（命令行应用程序）.​​.....我想执行这个应用程序，并提供输入到后，我想分析，这将导致它的输出。因为，它会输出很多东西，我希望拿，只是我需要从它的事情...

I want to execute an application(command line application) from the C#... and I want after executing this application and providing the input to it, I want to parse the output that will result it. Since, it will output many things, and I want to take, just the things that I need it from it...

我怎样才能做到这一点？

How can I do that ??

我怎样才能获得在C＃中的输出，然后我需要从它只拿东西??

How can I get the output in the c# and then take only the things I need it from it ??

有关执行C＃中的命令行......我想用杰夫MC的方式，他在此线程解释它

推荐答案

有就是让所有的输出事件，当他们被其他控制台应用程序的输出 cmd_DataReceived 被提出每当有输出和 cmd_Error 被提出每当有其他应用程序引发的错误。

There is one more way of getting all the output as events as and when they are output by the other console application cmd_DataReceived gets raised whenever there is output and cmd_Error gets raised whenever there is an error raised in the other application.

如果你想解析输出，可能是处理这些事件是一个更好的方式发生时读取输出，并在其他应用程序处理错误和

If you want to parse the output, probably handling these events is a better way to read output and handle errors in the other application as and when they occur.

using System;
using System.Diagnostics;

namespace InteractWithConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            ProcessStartInfo cmdStartInfo = new ProcessStartInfo();
            cmdStartInfo.FileName = @"C:\Windows\System32\cmd.exe";
            cmdStartInfo.RedirectStandardOutput = true;
            cmdStartInfo.RedirectStandardError = true;
            cmdStartInfo.RedirectStandardInput = true;
            cmdStartInfo.UseShellExecute = false;
            cmdStartInfo.CreateNoWindow = true;

            Process cmdProcess = new Process();
            cmdProcess.StartInfo = cmdStartInfo;
            cmdProcess.ErrorDataReceived += cmd_Error;
            cmdProcess.OutputDataReceived += cmd_DataReceived;
            cmdProcess.EnableRaisingEvents = true;
            cmdProcess.Start();
            cmdProcess.BeginOutputReadLine();
            cmdProcess.BeginErrorReadLine();

            cmdProcess.StandardInput.WriteLine("ping www.bing.com");     //Execute ping bing.com
            cmdProcess.StandardInput.WriteLine("exit");                  //Execute exit.

            cmdProcess.WaitForExit();
        }

        static void cmd_DataReceived(object sender, DataReceivedEventArgs e)
        {
            Console.WriteLine("Output from other process");
            Console.WriteLine(e.Data);
        }

        static void cmd_Error(object sender, DataReceivedEventArgs e)
        {
            Console.WriteLine("Error from other process");
            Console.WriteLine(e.Data);
        }
    }
}
