The accepted answer on this page has a weakness that is troublesome in rare situations. There are two file handles which programs write to by convention, stdout, and stderr. If you just read a single file handle such as the answer from Ray, and the program you are starting writes enough output to stderr, it will fill up the output stderr buffer and block. Then your two processes are deadlocked. The buffer size may be 4K. This is extremely rare on short-lived programs, but if you have a long running program which repeatedly outputs to stderr, it will happen eventually. This is tricky to debug and track down.

有一些很好的方法来处理这个问题。

One way is to execute cmd.exe instead of your program and use the /c argument to cmd.exe to invoke your program along with the "2>&1" argument to cmd.exe to tell it to merge stdout and stderr. var p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.Arguments = "/c mycmd.exe 2>&1"; Another way is to use a programming model which reads both handles at the same time. var p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.Arguments = @"/c dir \windows"; p.StartInfo.CreateNoWindow = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardInput = false; p.OutputDataReceived += (a, b) => Console.WriteLine(b.Data); p.ErrorDataReceived += (a, b) => Console.WriteLine(b.Data); p.Start(); p.BeginErrorReadLine(); p.BeginOutputReadLine(); p.WaitForExit();

您将需要使用ProcessStartInfo并启用RedirectStandardOutput -然后您可以读取输出流。您可能会发现使用“>”将输出重定向到文件(通过操作系统)更容易，然后只需读取该文件。

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。

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();
        }

 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();
 }

这里有一个小例子:

using System;
using System.Diagnostics;

class Program
{
    static void Main(string[] args)
    {
        var p = Process.Start(
            new ProcessStartInfo("git", "branch --show-current")
            {
                CreateNoWindow = true,
                UseShellExecute = false,
                RedirectStandardError = true,
                RedirectStandardOutput = true,
                WorkingDirectory = Environment.CurrentDirectory
            }
        );

        p.WaitForExit();
        string branchName =p.StandardOutput.ReadToEnd().TrimEnd();
        string errorInfoIfAny =p.StandardError.ReadToEnd().TrimEnd();

        if (errorInfoIfAny.Length != 0)
        {
            Console.WriteLine($"error: {errorInfoIfAny}");
        }
        else { 
            Console.WriteLine($"branch: {branchName}");
        }

    }
}

我相信这是最短的形式。

请注意，大多数命令行工具很容易混淆标准输出和标准错误，有时将它们组合成一个字符串是有意义的。

p.e exitcode有时也很有用。

上面的例子用于编写命令行工具，如果你想自己做的话。请注意，对于cli自动化，也可以使用Cake Frosten和Cake Git扩展。
