将控制台输出镜像到文件

在C＃控制台应用程序中，是否存在将控制台输出镜像到文本文件的明智方法？

Currently I am just passing the same string to both Console.WriteLine and InstanceOfStreamWriter.WriteLine in a log method.

最佳答案

这可能需要更多工作，但我会反其道而行之。

Instantiate a TraceListener for the console and one for the log file; thereafter use Trace.Write statements in your code instead of Console.Write. It becomes easier afterwards to remove the log, or the console output, or to attach another logging mechanism.

static void Main(string[] args)
{
    Trace.Listeners.Clear();

    TextWriterTraceListener twtl = new TextWriterTraceListener(Path.Combine(Path.GetTempPath(), AppDomain.CurrentDomain.FriendlyName));
    twtl.Name = "TextLogger";
    twtl.TraceOutputOptions = TraceOptions.ThreadId | TraceOptions.DateTime;

    ConsoleTraceListener ctl = new ConsoleTraceListener(false);
    ctl.TraceOutputOptions = TraceOptions.DateTime;

    Trace.Listeners.Add(twtl);
    Trace.Listeners.Add(ctl);
    Trace.AutoFlush = true;

    Trace.WriteLine("The first line to be in the logfile and on the console.");
}

据我所知，您可以在应用程序配置中定义侦听器，从而可以在不触摸构建的情况下激活或停用日志记录。
