else or return?

Question

Which one out of following two is best wrt to performance and standard practice. How does .NET internally handles these two code snippets?

Code1

If(r         


        

Answer 1

If there is common code, that needs to be executed after the if/else block, then option 1.

If the if-else block is the last thing to do in a function, then option 2.

Personally I always use option 1. If there is a return stateent, it comes after the else block
