Question on returning values from VBScript to .NET

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 开发者_高级运维method? Thanks.

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

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());
        }
