I have the same intention as in this question:
Automatically call all functions matching a certain pattern in python
But I needed the solution (if technically possible) in VB.NET. Is that possible in VB.NET ?

Sure you can do that, that's what reflection is for:
Imports System.Reflection
Module Module1
Sub Main()
Dim methods = GetType(Module1).GetMethods() _
.Where(Function(m) m.Name.StartsWith("Setup"))
For Each method As MethodInfo In methods
method.Invoke(Nothing, Nothing)
Next
End Sub
Sub Setup1()
Console.WriteLine(1)
End Sub
Sub Setup2()
Console.WriteLine(2)
End Sub
Sub Setup3()
Console.WriteLine(3)
End Sub
End Module

@svick, sorry I'm a newbie and I just tested your code and visual studio 2008 showed following error: Leading '.' or '!' can only appear inside a 'With' statement.

@david, sorry, I forgot you can't continue line in VB just like in C#, see updated answer.

VB.NET 10 (introduced with VS 2010) supports implicit line continuation without using the
_ character.Sean
@Cody Gray, many thanks ! That is new info for me. VB.NET is getting smarter.

@david: You're welcome. I suppose it's good to know... I still use the line continuation characters out of habit. VB.NET may be getting smarter, but I'm clearly not. :-) Also do keep in mind that while Reflection will certainly work for this, there is a performance penalty involved in invoking functions this way. It's not nearly as fast as a direct call to the function. That may be perfectly OK for your purposes, but it's certainly worth knowing about regardless.
