>Doesn't work that way in C#. Be very surprised if that was the case in VB.NET - the type of 'Me' will be the type of the instance.

If I would like to have it like this, how would I pass the 3rd parameter:
    ' If a method exists in a sub class. This is used when we negotiate with the Overrides method. Thus, the framework
    ' may know if the Overrides method exists in the sub class. This is used in the DataEntry class. So, if the method
    ' does not exist, we do not call it. And, if it exists, it allows us to validate, if necessary, before proceeding.
    ' expO1 Originator
    ' expC1 Name of the method
    Public Function IsMethodExistInSubClass(ByVal toClass As Object, ByVal tcMethod As String, _
     ByVal toBaseClass As Object) As Boolean
        Dim llExist As Boolean = False
        Dim loType As Type = Nothing
        Dim loMethodInfo As System.Reflection.MethodInfo = Nothing

        ' Get a reference to the originator type
        loType = toClass.GetType()

        ' Get a reference to the method
        loMethodInfo = loType.GetMethod(tcMethod, System.Reflection.BindingFlags.Instance Or System.Reflection.BindingFlags.Public)

        ' If the method does not exist
        If loMethodInfo Is Nothing Then
            Return False
        End If

        ' If the method exists in the sub class
        If loMethodInfo.DeclaringType <> toBaseClass.GetType() Then
            llExist = True
        End If

        Return llExist
    End Function
