Question

I was developing a website by using c# with .net framework 4. OO concepts have been implemented. Each layer has some Try Catch blocks used to handle different errors and return different error messages. I found that it getting slower when loading as the try catch block getting more and more. I wonder this is because why. Any alternative solution? Correct me if I am wrong. Appreciate for any reply.

Answer 1

There is nothing wrong with using try/catch blocks. They don’t alter performance. what does alter performance is throwing errors!

see web site below particularly:

Throwing exceptions can be very expensive, so make sure that you don’t
throw a lot of them. Use Perfmon to see how many exceptions your
application is throwing. It may surprise you to find that certain
areas of your application throw more exceptions than you expected. For
better granularity, you can also check the exception number
programmatically by using Performance Counters.
