Is it Dynamic Casting/ Converting or Reflection C#.NET?

If you really want the solution you're asking for, the code below is one example. But it's more likely that you're asking the wrong question. A better option would be to create an abstraction layer through an interface or an abstract class that holds the "Ref_Number" property, and use that in your methods.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
