Using Exceptions throwing in C#. Does it affect a performance?

Question

Basically, the question is: Do the Exceptions in C# affect the performance a lot? Is it better to avoid Exceptions rethrow? If i generate an exception in my code, does it affect a performance?

Sorry for the sillines of the question itself

Answer 1

If you're worried about exception performance, you're using them wrong.

But yes, exceptions do affect performance.
