可重复喂养输入到一个进程的标准输入 [英] Repeatably Feeding Input to a Process' Standard Input

问题描述

我有一个（C＃）控制台一种保持状态的应用程序。状态，其可通过控制台馈送与各种输入该应用程序来改变。我需要能够既饲料用比特输入的应用程序，然后读取输出漂洗并重复

I have a (C#) console application which maintains a state. The state can be altered by feeding the application with various input through the console. I need to be able to both feed the application with a bit of input, then read the output rinse and repeat.

我创建了一个新的进程，并尽一切重定向输入/输出的正常工作。现在的问题是，我已经发出后输入和呼叫的ReadLine（）在标准输出不前，我打电话返回一个值关闭（） 后，我不能写了输入流的标准输入。

I create a new process and do all of the normal work of redirecting the input/output. The problem is that after I've sent input and call ReadLine() on the standard output it does not return a value before I call Close() on the standard input after which I cannot write anymore to the input stream.

我怎样才能保持打开输入流，同时还接收输出？

How can I keep open the input stream while still receiving output?

 var process = new Process
                          {
                              StartInfo =
                                  {
                                      FileName =
                                          @"blabal.exe",
                                      RedirectStandardInput = true,
                                      RedirectStandardError = true,
                                      RedirectStandardOutput = true,
                                      UseShellExecute = false,
                                      CreateNoWindow = true,
                                      ErrorDialog = false
                                  }
                          };


        process.EnableRaisingEvents = false;

        process.Start();

        var standardInput = process.StandardInput;
        standardInput.AutoFlush = true;
        var standardOutput = process.StandardOutput;
        var standardError = process.StandardError;

        standardInput.Write("ready");
        standardInput.Close(); // <-- output doesn't arrive before after this line
        var outputData = standardOutput.ReadLine();

        process.Close();
        process.Dispose();

控制台应用程序，我从重定向IO是很简单的。它从控制台读取使用 Console.Read（）和使用 Console.Write（）写它。我肯定知道这个数据是可读的，因为我从它使用标准输入/输出（写在.NET）。

The console application I'm redirecting IO from is very simple. It reads from the console using Console.Read() and writes to it using Console.Write(). I know for certain that this data is readable, since I have another application that reads from it using standard output / input (not written in .NET).

推荐答案

这是正在发生的事情，因为你正在使用写（准备好了）这是会追加一个字符串到文本，而不是使用的WriteLine（准备好了）。就这么简单：）

That is happening because of you are using Write("ready") which is will append a string to the text, instead use WriteLine("ready"). that simple :).
