Returning a string from a C# console application to VBScript

Question

On one of my VBScripts, I have to call a C# console application.

AFTER the C# application finishes executing (synchronous), I need to get the output of the C# application, which is a string, into the VBScript.

System.Environment.ExitCode in C# only allows an Integer to be returned.

How can I have get the string that is output by the C# application into the VBScript?

I realize that it is possible to save the output of the C# application to a file and read that using VBScript. However, I was looking for something less messy.

Any solutions/suggestions are welcome.

For example: Is there some way to create a DLL and use this to enable a return string value to be passed to VBScript? I am not sure. This is just a thought. Is there a way to create something similar to Shell.Application BrowseForFolder?

Thanks for all your help!

Any particular reason not to use PowerShell for scripting instead of VBScript? It is soooo much easier to call .Net code from PowerShell. — Alexei Levenkov

Thanks for the reply! This script is being executed from within a 3rd party application which only supports VbScripts. — slayernoah

You can use a WScript.Shell object to execute the C# process, and then read from it's StdOut filestream.

For details, see this tek-tip on the subject.

For details I'd rather refer to the documentation.

On the C# program, how can I write to the Stdout so that it will be read by the VbScript?

@slayernoah Console.WriteLine writes to standard output.

@ReedCopsey Is there any way we could get it to work the same way without the WScript.Shell object? The environment it runs in doesn't have this object. Thanks!

@slayernoah How are you running VBScript? WScript.Shell is part of the Windows Scripting host, which is what runs VBScript...
