Casting problem in C# generic method?

I don't get what you are trying to do with that code.

Primarly I think, this code snippet has bad design. If you add "ThingD" class, you need change in another part of code, for clear behaviour. You should use something like.

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.
