Hi Michel,

Here is a little suggestion to refactor your original code in order to make it simplier and easier to maintain:

Private Function InList(ByVal searchedWord As String, ByVal ParamArray listOfWords() As String) As Boolean

    For Each word As String In listOfWords
        If word = searchedWord Then
            Return True
        End If
    Next
    Return False

End Function

It uses a feature from VB.NET (also existing in C#) called array parameters. The reserved word ParamArray at the function signature indicates that the function can receive a variable number of parameters from the second parameter on. The values passed as parameters are stored into an array and you can access its members as you'd normally do with regular arrays.

This makes your function work with an arbitrarly long list of parameters, which, IMHO, makes its design more flexible, optimized and robust.

HTH.
