Is it possible to detect wheter a MethodInfo object refers to a sub or to a function?

I'd like to distinguish between these two cases, for example in this code:

    For Each method As Reflection.MethodInfo In Type.GetType("WindowsApplication2.clsTest").GetMethods()
        Select Case method.Name
            Case "ToString", "Equals", "GetHashCode", "GetType"
            Case Else
                Debug.Print(method.GetType().ToString)
            End Select
    Next

Or, even better, is it possible to iterate only over subs or functions?

Thank you.
