有关将值从VBScript返回到.NET的问题 [英] Question on returning values from VBScript to .NET

问题描述

我正在尝试建立一个能够从.NET运行VBScript文件的应用程序（请参阅此处），并且大多数设置都很好，但是我想对此进行测试，因此我需要能够从我的VBScripts返回数据。我发现我可以使用WScript.Quit（[ErrorCode]）来获取整数值，但是返回字符串呢？是否可以将它们提供给DataReceivedEventHandler？还是我需要看看其他方法？谢谢。

i'm trying to set up an application capable of running VBScript files from .NET (See here), and have most of it set up fine, but I want to test this out, so I need to be able to return data from my VBScripts. I've found that I can use WScript.Quit([ErrorCode]) to get back an integer value, but what about returning strings? Is it possible to feed them out to the DataReceivedEventHandler? Or do I need to look at a different method? Thanks.

推荐答案

您可以写入标准输出（它将输出重定向到事件处理程序）。我相信在VBScript中这是WScript.Stdout。

You can write to the standard output (which will redirect it to the event handler). I believe in VBScript this is WScript.Stdout.

如果您写了多行，则可以考虑使用StringWriter之类的东西来捕获它们，即

If you have multiple lines written out you may consider using something like a StringWriter to capture them all, ie

        var p = new Process()
        {
            StartInfo = new ProcessStartInfo("netstat")
            {
                RedirectStandardOutput = true,
                RedirectStandardError = true,
                UseShellExecute = false,
            }
        };

        var outputWriter = new StringWriter();
        p.OutputDataReceived += (sender, args) => outputWriter.WriteLine(args.Data);

        var errorWriter = new StringWriter();
        p.ErrorDataReceived += (sender, args) => errorWriter.WriteLine(args.Data);

        p.Start();
        p.BeginOutputReadLine();
        p.BeginErrorReadLine();     
        p.WaitForExit();

        if (p.ExitCode == 0)
        {
            Console.WriteLine(outputWriter.GetStringBuilder().ToString());
        }
        else
        {
            Console.WriteLine("Process failed with error code {0}\nMessage Was:\n{1}", p.ExitCode
                , errorWriter.GetStringBuilder().ToString());
        }
