如果您试图查询PC/服务器上的本地ARP缓存，这可能对某人有用。

List<string[]> results = new List<string[]>();

        using (Process p = new Process())
        {
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.Arguments = "/c arp -a";
            p.StartInfo.FileName = @"C:\Windows\System32\cmd.exe";
            p.Start();

            string line;

            while ((line = p.StandardOutput.ReadLine()) != null)
            {
                if (line != "" && !line.Contains("Interface") && !line.Contains("Physical Address"))
                {
                    var lineArr = line.Trim().Split(' ').Select(n => n).Where(n => !string.IsNullOrEmpty(n)).ToArray();
                    var arrResult = new string[]
                {
                   lineArr[0],
                   lineArr[1],
                   lineArr[2]
                };
                    results.Add(arrResult);
                }
            }

            p.WaitForExit();
        }

您可以使用Process类启动任何命令行程序，并使用您创建的流阅读器(基于字符串或内存位置)设置Process实例的StandardOutput属性。流程完成后，您就可以在流上执行所需的任何diff。

在PublicDomain开源代码中有一个ProcessHelper类，你可能会感兴趣。

朱利安的解决方案经过了一些小的修正。下面是一个同样使用https://sourceforge.net/projects/bat-to-exe/ GenericConsole.cs和https://www.codeproject.com/Articles/19225/Bat-file-compiler program.txt作为args部分的例子:

using System;
using System.Text;  //StringBuilder
using System.Diagnostics;
using System.IO;


class Program
{
    private static bool redirectStandardOutput = true;

    private static string buildargument(string[] args)
    {
        StringBuilder arg = new StringBuilder();
        for (int i = 0; i < args.Length; i++)
        {
            arg.Append("\"" + args[i] + "\" ");
        }

        return arg.ToString();
    }

    static void Main(string[] args)
    {
        Process prc = new Process();
        prc.StartInfo = //new ProcessStartInfo("cmd.exe", String.Format("/c \"\"{0}\" {1}", Path.Combine(Environment.CurrentDirectory, "mapTargetIDToTargetNameA3.bat"), buildargument(args)));
        //new ProcessStartInfo(Path.Combine(Environment.CurrentDirectory, "mapTargetIDToTargetNameA3.bat"), buildargument(args));
        new ProcessStartInfo("mapTargetIDToTargetNameA3.bat");
        prc.StartInfo.Arguments = buildargument(args);

        prc.EnableRaisingEvents = true;

        if (redirectStandardOutput == true)
        {
            prc.StartInfo.UseShellExecute = false;
        }
        else
        {
            prc.StartInfo.UseShellExecute = true;
        }

        prc.StartInfo.CreateNoWindow = true;

        prc.OutputDataReceived += OnOutputDataRecived;
        prc.ErrorDataReceived += OnErrorDataReceived;
        //prc.Exited += OnExited;

        prc.StartInfo.RedirectStandardOutput = redirectStandardOutput;
        prc.StartInfo.RedirectStandardError = redirectStandardOutput;

        try
        {
            prc.Start();
            prc.BeginOutputReadLine();
            prc.BeginErrorReadLine();
            prc.WaitForExit();
        }
        catch (Exception e)
        {
            Console.WriteLine("OS error: " + e.Message);
        }

        prc.Close();
    }

    // Handle the dataevent
    private static void OnOutputDataRecived(object sender, DataReceivedEventArgs e)
    {
        //do something with your data
        Console.WriteLine(e.Data);
    }

    //Handle the error
    private static void OnErrorDataReceived(object sender, DataReceivedEventArgs e)
    {
        Console.WriteLine(e.Data);
    }

    // Handle Exited event and display process information.
    //private static void OnExited(object sender, System.EventArgs e)
    //{
    //    var process = sender as Process;
    //    if (process != null)
    //    {
    //        Console.WriteLine("ExitCode: " + process.ExitCode);
    //    }
    //    else
    //    {
    //        Console.WriteLine("Process exited");
    //    }
    //}
}

代码需要在VS2007内部编译，使用命令行csc.exe生成的可执行文件将不能正确显示控制台输出，甚至崩溃与CLR20r3错误。注释掉OnExited事件过程，蝙蝠到exe的控制台输出将更像原来的蝙蝠控制台输出。

 System.Diagnostics.ProcessStartInfo psi =
   new System.Diagnostics.ProcessStartInfo(@"program_to_call.exe");
 psi.RedirectStandardOutput = true;
 psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
 psi.UseShellExecute = false;
 System.Diagnostics.Process proc = System.Diagnostics.Process.Start(psi); ////
 System.IO.StreamReader myOutput = proc.StandardOutput;
 proc.WaitForExit(2000);
 if (proc.HasExited)
  {
      string output = myOutput.ReadToEnd();
 }

如果您试图查询PC/服务器上的本地ARP缓存，这可能对某人有用。

List<string[]> results = new List<string[]>();

        using (Process p = new Process())
        {
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.Arguments = "/c arp -a";
            p.StartInfo.FileName = @"C:\Windows\System32\cmd.exe";
            p.Start();

            string line;

            while ((line = p.StandardOutput.ReadLine()) != null)
            {
                if (line != "" && !line.Contains("Interface") && !line.Contains("Physical Address"))
                {
                    var lineArr = line.Trim().Split(' ').Select(n => n).Where(n => !string.IsNullOrEmpty(n)).ToArray();
                    var arrResult = new string[]
                {
                   lineArr[0],
                   lineArr[1],
                   lineArr[2]
                };
                    results.Add(arrResult);
                }
            }

            p.WaitForExit();
        }
