I know that exceptions have a performance penalty, and that it's generally more efficient to try and avoid exceptions than to drop a big try/catch around everything -- but what about the try block itself? What's the cost of merely declaring a try/catch, even if it never throws an exception?

The performance cost of try is very small. The major cost of exception handling is getting the stack trace and other metadata, and that's a cost that's not paid until you actually have to throw an exception.

But this will vary by language and implementation. Why not write a simple loop in C# and time it yourself?
