使用c#运行交互式命令行exe

Question

我可以使用命令行进程process.start().我可以使用标准输入提供输入.之后,当进程再次要求用户输入时,我的程序如何知道并将输入传递给该exe？

这里有一个例子,听起来与你需要的相似,使用Process.StandardInput和a StreamWriter.

        Process sortProcess;
        sortProcess = new Process();
        sortProcess.StartInfo.FileName = "Sort.exe";

        // Set UseShellExecute to false for redirection.
        sortProcess.StartInfo.UseShellExecute = false;

        // Redirect the standard output of the sort command.  
        // This stream is read asynchronously using an event handler.
        sortProcess.StartInfo.RedirectStandardOutput = true;
        sortOutput = new StringBuilder("");

        // Set our event handler to asynchronously read the sort output.
        sortProcess.OutputDataReceived += new DataReceivedEventHandler(SortOutputHandler);

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

        // Use a stream writer to synchronously write the sort input.
        StreamWriter sortStreamWriter = sortProcess.StandardInput;

        // Start the asynchronous read of the sort output stream.
        sortProcess.BeginOutputReadLine();
        Console.WriteLine("Ready to sort up to 50 lines of text");
        String inputText;
        int numInputLines = 0;
        do 
        {
            Console.WriteLine("Enter a text line (or press the Enter key to stop):");

            inputText = Console.ReadLine();
            if (!String.IsNullOrEmpty(inputText))
            {
                numInputLines ++;
                sortStreamWriter.WriteLine(inputText);
            }
        }

希望有所帮助
