如何保存控制台应用程序的输出 [英] How to save the output of a console application

问题描述

我需要关于如何通过标准输出有我的C＃控制台应用程序显示文本给用户，同时仍然是以后能够获得建议。实际的功能，我想实现是转储整个输出缓冲器到一个文本文件在程序执行结束。

I need advice on how to have my C# console application display text to the user through the standard output while still being able access it later on. The actual feature I would like to implement is to dump the entire output buffer to a text file at the end of program execution.

我用，而我的解决方法没有找到一个更简洁的方法是继承的TextWriter 覆盖的写作方法，使他们既能写一个文件，并调用原来的标准输出作家。事情是这样的：

The workaround I use while I don't find a cleaner approach is to subclass TextWriter overriding the writing methods so they would both write to a file and call the original stdout writer. Something like this:

public class DirtyWorkaround {
  private class DirtyWriter : TextWriter {
    private TextWriter stdoutWriter;
    private StreamWriter fileWriter;

    public DirtyWriter(string path, TextWriter stdoutWriter) {
      this.stdoutWriter = stdoutWriter;
      this.fileWriter = new StreamWriter(path);
    }

    override public void Write(string s) {
      stdoutWriter.Write(s);

      fileWriter.Write(s);
      fileWriter.Flush();
    }

    // Same as above for WriteLine() and WriteLine(string),
    // plus whatever methods I need to override to inherit
    // from TextWriter (Encoding.Get I guess).
  }

  public static void Main(string[] args) {
    using (DirtyWriter dw = new DirtyWriter("path", Console.Out)) {
      Console.SetOut(dw);

      // Teh codez
    }
  }
}

看到它写入并刷新该文件的所有时间。我喜欢只在执行结束做到这一点，但我无法找到任何方式来访问输出缓冲区。

See that it writes to and flushes the file all the time. I'd love to do it only at the end of the execution, but I couldn't find any way to access to the output buffer.

此外，借口不准确上述code（不得不写的临时的，抱歉）。

Also, excuse inaccuracies with the above code (had to write it ad hoc, sorry ;).

推荐答案

对于这个完美的解决方案是使用 log4net的与控制台附加目的地和文件附加目的地。有很多可用的其他附加目的地也是如此。它还允许你把不同的附加目的地关闭，在运行时。

The perfect solution for this is to use log4net with a console appender and a file appender. There are many other appenders available as well. It also allows you to turn the different appenders off and on at runtime.
