与命令行应用程序交互的最佳方式 [英] Best way to interact with Command Line application

问题描述

我需要编写一个组件是一个命令行应用程序交互紧密的应用程序。命令行应用程序会询问一系列问题，进行一些计算，然后终止（我需要检测）。从本质上讲，我想结束这一互动的包装类。

I need to write a component for an application that interacts tightly with a command line application. The command line application asks a series of questions, performs some computations, then terminates (which i need to detect). Essentially, i want to wrap up this interaction in a wrapper class.

有没有人取得过类似的？如果是这样，你怎么做呢？你有没有注意到一个模式，或者一些好身材在课堂上使用？干杯！

Has any one achieved similar in the past? If so, how did you go about it? Did you notice a pattern, or maybe some good build in classes to use? Cheers!

推荐答案

您需要重定向输入和输出流，使用进程;这是稍微复杂一些，同时处理，因为你必须要小心，事情并没有迷失在缓冲区（导致死锁）。

You would need to redirect both the input and output streams, using Process; it is slightly trickier handling both, since you need to be careful that things aren't lost in the buffers (causing deadlock).
