Hello I will preface this by saying Im previously an asp developer and am learning oop programming/Vb.Net
Im working on a 3 tier architecture and trying to abstract my code as much as possible since I have a very large intranet to convert. In my business layer I am defining my classes with management methods. Below is an example of one of my classes.
My question: Is there a way for me to genericaly refer to the class type and object type so that I dont have to continualy refer to the class name/type "ServiceRequest" throughout the class. For example something like:
"Public Function GetItem(ByVal ID As Integer) As Me.GetType"? Any info if this is possible and what topic i should research would be appreciated. Feel free to comment on the code in general if im doing something glaringly wrong. Thanks
