如何使用来自另一个.NET程序的交互式命令行程序

我需要为交互式命令行程序编写一个包装器.

这意味着我需要能够通过其标准输入向其他程序发送命令,并通过其标准输出接收响应.

问题是,当输入流仍处于打开状态时,标准输出流似乎被阻止.一旦我关闭输入流,我就得到响应.但后来我无法发送更多命令.

这就是我目前使用的(主要来自这里):

void Main() {
    Process process;
    process = new Process();
    process.StartInfo.FileName = "atprogram.exe";
    process.StartInfo.Arguments = "interactive";

    // Set UseShellExecute to false for redirection.
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.CreateNoWindow = true;

    // Redirect the standard output of the command.  
    // This stream is read asynchronously using an event handler.
    process.StartInfo.RedirectStandardOutput = true;
    // Set our event handler to asynchronously read the output.
    process.OutputDataReceived += (s, e) => Console.WriteLine(e.Data);

    // Redirect standard input as well. This stream is used synchronously.
    process.StartInfo.RedirectStandardInput = true;
    process.Start();

    // Start the asynchronous read of the output stream.
    process.BeginOutputReadLine();

    String inputText;
    do 
    {
        inputText = Console.ReadLine();
        if (inputText == "q")
        {
            process.StandardInput.Close();   // After this line the output stream unblocks
            Console.ReadLine();
            return;
        }
        else if (!String.IsNullOrEmpty(inputText))
        {
            process.StandardInput.WriteLine(inputText);
        }
    }
}

我也尝试同步读取标准输出流,但结果相同.无限期地对输出流块进行任何方法调用,直到输入流关闭为止 - 偶数Peek()和EndOfStream.

有没有办法以全双工的方式与其他进程通信？
