我正在使用 C# 编写用于脚本语言的自定义 IDE,但我遇到了问题。

我正在尝试启动编译器进程(pawncc.exe)并将参数传递给它。我已经这样做了,现在我遇到了问题。当我想显示编译器应用程序的输出时,它只显示其中的一部分。它应该输出这个(从命令提示符得到这个):

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。它输出这个(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.

我就是不明白!这真是一件很奇怪的事情。这可能很简单,但我一直在研究它,并且研究了几个小时!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,发现您只是只读的 StandardOutput 流。

我通常使用流程上的 DataReceived 事件监控标准和错误输出流的流程,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);
        }
    }

这显然有一些变化,但这应该让你开始。

在过去处理衍生进程的原始输出/错误流时,我注意到了一些零星的问题,因此我通常通过事件处理捕获的输出:

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.EnableRaisingEvents = true;
myProcess.OutputDataReceived += OnOutputDataReceived;
myProcess.ErrorDataReceived += OnErrorDataReceived;
myProcess.StartInfo = startInfo;
myProcess.Start();
myProcess.BeginOutputReadLine();
myProcess.BeginErrorReadLine();

我没有 pawnCC 应用程序,所以我无法尝试,但似乎它们将调试信息的详细程度限制为外部应用程序 - 除了命令提示符。

您可以尝试通过 cmd 生成 pawncc.exe:

"cmd.exe \c CommandParameterToLaunchPawnCCwithArguments"
