重定向也显示过程的输出流 [英] Redirect but also display process output stream

问题描述

我正在运行的内部版本，我希望能够因为它发生在查看进度。但我也想保存输出，如果构建有错误。

I am running a build, and I would like to be able to view the progress as it happens. But I would also like to save the output if the build has an error.

我知道我可以使用 Process.UseShellExecute = FALSE 和 RedirectStandardOutput ，但这只是故事的一部分。

I know I can use Process.UseShellExecute = false, and RedirectStandardOutput, but that's only part of the story.

我怎样才能做到这一点？

How can I do this?

推荐答案

更新

由于格雷格提及在下面的意见，MSBuild的可以写入到一个日志文件，同时输出到控制台开箱。

As Greg mentions in the comments below, MSBuild can write out to a log file while also outputting to console out of the box.

MSBuild [options] /filelogger /fileloggerparameters:LogFile=MSBuildLog.txt

请尝试以下简单的C＃程序。这将需要重定向STDIN（ Console.In ），并将其写入到一个或多个文件和标准输出（ Console.Out ）

---

Try the following simple C# program. It will take the redirected STDIN (Console.In) and write it to one or more files and STDOUT (Console.Out).

using System;
using System.Collections.Generic;
using System.IO;

namespace RedirectToFile
{
    class Program
    {
        static void Main(string[] args)
        {
            var buffer = new char[100];
            var outputs = new List<TextWriter>();

            foreach (var file in args)
                outputs.Add(new StreamWriter(file));

            outputs.Add(Console.Out);

            int bytesRead;
            do
            {
                bytesRead = Console.In.ReadBlock(buffer, 0, buffer.Length);
                outputs.ForEach(o => o.Write(buffer, 0, bytesRead));
            } while (bytesRead == buffer.Length);

            outputs.ForEach(o => o.Close());
        }
    }
}

我用它来重定向从一个MSBuild批处理文件输出到磁盘的，而的还是输出到控制台窗口

I use it to redirect the output from an MSBuild batch file to disk whilst still outputting to the console window.

Usage: MSBuild [options] | RedirectToFile.exe MSBuildLog.txt
