ASP.NET (C#) Question

How to call a VBScript file in a C# application?

I need to call a VBScript file (.vbs file extension) in my C# Windows application.
How can I do this?

There is an add-in to access a VBScript file
in Visual Studio.
But I need to access the script in code behind. How to do this?


The following code will execute a VBScript script with no prompts or errors and no shell logo.

System.Diagnostics.Process.Start(@"cscript //B //Nologo c:\scripts\vbscript.vbs");

A more complex technique would be to use:

Process scriptProc = new Process();
scriptProc.StartInfo.FileName = @"cscript"; 
scriptProc.StartInfo.WorkingDirectory = @"c:\scripts\"; //<---very important 
scriptProc.StartInfo.Arguments ="//B //Nologo vbscript.vbs";
scriptProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; //prevent console window from popping up
scriptProc.WaitForExit(); // <-- Optional if you want program running until your script exit

Using the StartInfo properties will give you quite granular access to the process settings.

You need to use Windows Script Host if you want windows, etc. to be displayed by the script program. You could also try just executing cscript directly but on some systems it will just launch the editor :)
