var type in C# - casting it and use as a parameter

[bortkevb]

I'm trying to minimize DB trips while using LINQ. I got data that I needed into VAR , but I bumped into couple of roadblocks:

1. how do I make VAR public(or at least internal)
2. how do I pass it as a parameter.

I realize that I can just loop thru and reassign to "normal" collection, but I hope there is a vay to cast it somehow.

Thank you
