读取另一个正在运行的应用程序

Question

我正在使用C#中的自定义IDE编写脚本语言,我遇到了问题.

我正在尝试启动编译器进程(pawncc.exe)并将参数传递给它.我已经做到了,现在我遇到了问题.当我想显示编译器应用程序的输出时,它只显示它的某些部分.它应该输出这个(从命令提示符获取):

Pawn compiler 3.2.3664                  Copyright (c) 1997-2006, ITB CompuPhase

newGM.pwn(0) : fatal error 100: cannot read from file: "includes/main_include.inc"

Compilation aborted.
1 Error.

但事实并非如此.它输出(在应用程序中,使用相同的命令/参数):

Pawn compiler 3.2.3664          Copyright (c) 1997-2006, ITB CompuPhase


1 Error.

我只是不明白!这真的很奇怪.这可能是一件简单的事情,但我一直在研究它,现在研究几个小时!这是我的代码:

        public Form3(string path)
        {
            InitializeComponent();

            this._path = path;

            Process myProcess = new Process();
            ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
            startInfo.CreateNoWindow = true;
            startInfo.UseShellExecute = false;
            startInfo.RedirectStandardOutput = true;
            startInfo.Arguments = path + " -r -d2";
            myProcess.StartInfo = startInfo;
            myProcess.Start();

            while (true)
            {
                string myString;
                byte[] buffer = new byte[512];
                var ar = myProcess.StandardOutput.BaseStream.BeginRead(buffer, 0, 512, null, null);
                ar.AsyncWaitHandle.WaitOne();
                var bytesRead = myProcess.StandardOutput.BaseStream.EndRead(ar);
                if (bytesRead > 0)
                {
                    myString = Encoding.ASCII.GetString(buffer, 0, bytesRead);
                }
                else
                {
                    myProcess.WaitForExit();
                    break;
                }
                richTextBox1.Text = myString;

            }

        }

!!编辑:

它对这段代码做了同样的事情:

        public Form3(string path)
        {
            InitializeComponent();

            this._path = path;

            Process myProcess = new Process();
            ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
            startInfo.CreateNoWindow = true;
            startInfo.UseShellExecute = false;
            startInfo.RedirectStandardOutput = true;
            startInfo.RedirectStandardError = true;
            startInfo.Arguments = path + " -r -d2";
            myProcess.StartInfo = startInfo;
            myProcess.Start();

            using (StreamReader reader = myProcess.StandardOutput)
            {
                string result = reader.ReadToEnd();
                richTextBox1.Text = result;
            }
        }

您还需要重定向标准错误流:

startInfo.RedirectStandardError = true;

编辑:我刚刚查看了代码并发现您只是只读StandardOutput流.

我通常使用进程上的DataReceived事件监视标准和错误输出流的进程,并将结果添加到stringbuilder中,然后将StringBuilder内容存储在UI元素中:

    private static System.Text.StringBuilder m_sbText;

    public Form3(string path)
    {
        InitializeComponent();

        this._path = path;

        Process myProcess = new Process();
        ProcessStartInfo startInfo = new ProcessStartInfo("pawncc.exe");
        startInfo.CreateNoWindow = true;
        startInfo.UseShellExecute = false;
        startInfo.RedirectStandardOutput = true;
        startInfo.RedirectStandardError = true;
        startInfo.Arguments = path + " -r -d2";
        myProcess.StartInfo = startInfo;

        m_sbText = new System.Text.StringBuilder(1000);

        myProcess.OutputDataReceived += ProcessDataHandler;
        myProcess.ErrorDataReceived += ProcessDataHandler;

        myProcess.Start();

        myProcess.BeginOutputReadLine();
        myProcess.BeginErrorReadLine();

        while (!myProcess.HasExited)
        {
            System.Threading.Thread.Sleep(500);
            System.Windows.Forms.Application.DoEvents();
        }
        RichTextBox1.Text = m_sbText.ToString();
    }

    private static void ProcessDataHandler(object sendingProcess, DataReceivedEventArgs outLine)
    {
        // Collect the net view command output. 
        if (!String.IsNullOrEmpty(outLine.Data))
        {
            // Add the text to the collected output.
            m_sbText.AppendLine(outLine.Data);
        }
    }

这有明显的变化,但这应该让你开始.
