读取已经打印到控制台的值 [英] Read values already printed to the console

问题描述

这可能是完全不可能的，但是我想知道是否有一种方法可以读取控制台已经打印的值。例如，如果控制台打印

This may be completely impossible, but I was wondering if there is a way to read values that the console has already printed. For example, if the console printed

您正以10m / s的速度向北行驶

You are travelling north at a speed of 10m/s

; ，

as a result of Console.WriteLine("You are travelling north at a speed of 10m/s");, is there a way of reading this line and then, for arguments sake, putting this value in a string?

基本上，我需要阅读已输出到的内容，有没有办法读取此行，然后出于参数目的将其放在字符串中？控制台，而不是用户输入。有办法吗？

Basically what I need is to read what has already been outputted to the console, not the user input. Is there a way?

预先感谢。

推荐答案

是。有一种方法。您可以 Console.SetOut 方法。

Yes. There is a way. You can Console.SetOut method.

将您的主要方法组织为；

Organize your main method as;

static void Main()
{
    using (StringWriter stringWriter = new StringWriter())
    {
         Console.SetOut(stringWriter);

         //All console outputs goes here
         Console.WriteLine("You are travelling north at a speed of 10m/s");

         string consoleOutput = stringWriter.ToString();
    }
}

然后 consoleOutput 应该为您以10m / s的速度向北行驶。

Then consoleOutput should have You are travelling north at a speed of 10m/s.
