Is it possible to use my VB program in C#?

Question

I've got a module in VB like this

Module Module1

    Sub Main()
        /* some piece of code here */
    End Sub

End Module

And I want to execute its Main from a project in C# because both the languages comes under .net so is there a way to achieve this?

VB what? `VB6`, `VB.NET`, `VBA` ... something else? If its not managed did you make it COM visible? Have you tried *anything* at all? — Igor, Oct 23 '17 at 15:02

Add reference

Build it as a DLL, put Public in front of some thing slike this

Public Module Module1
 ... Public sub Main

and add the dll as a reference to the c# project. DONE.

You can't use it like that.

see amy's comment. I swear I tried it at one point ... and failed... sorry about that.

You can add a reference to an executable, and you can call `main`. It's just a function. – Oct 23 '17 at 15:06

a VB.Net Module is a C# Static Class. so, if you reference the VB.Net Project or Vb.Net Compiled Assembly, you can call Main sub routine in this way:

Module1.Main();

but to do that, Module1 and Main must be marked as public:

Public Module Module1

    Public Sub Main()
        /* ..... */
    End Sub

End Module
