VB.NET - If string contains "value1" or "value2"

I'm wondering how I can check if a string contains either "value1" or "value2"? I tried this:

If strMyString.Contains("Something") Then

End if

This works, but this doesn't:

If strMyString.Contains("Something") or ("Something2") Then

End if

This gives me the error that conversion from string to Long can't be done. If I put the or ("Something2") inside the parenthesis of the first one, it gives me the error that the string cannot be converted to Boolean.

So how can I check if the string contains either "string1" or "string2" without having to write too much code?

I've approached this in a different way. I've created a function which simply returns true or false.. Usage:

If FieldContains("A;B;C",MyFieldVariable,True|False) then

.. Do Something

End If

Public Function FieldContains(Searchfor As String, SearchField As String, AllowNulls As Boolean) As Boolean

       If AllowNulls And Len(SearchField) = 0 Then Return True

        For Each strSearchFor As String In Searchfor.Split(";")
            If UCase(SearchField) = UCase(strSearchFor) Then
                Return True
            End If
        Next

        Return False

    End Function

If you want to disregard whether the text is uppercase or lowercase, use this:

   If strMyString.ToUpper.Contains("TEXT1") OrElse strMyString.ToUpper.Contains("TEXT2") Then
        'Something
   End if
