Any C# library to do webrequest similar to httpwebrequest but not throwing exceptions

Question

I 'm looking for a similar library or class like httpwebrequest which does not throw exceptions on http codes. (c# language) Problem with httpwebrequest is that it behaves the http error codes (like 401,403 and ...) as exceptions and throws an exception in case of these. You may know that exception throwing and handling is expensive. for example a successful request takes about 30 ms on my system,but another request which causes exception takes about 250! I 'm making lots of request that causes this http error codes and it affects my code performance alot. I have tried webclient,webrequest,httpclient and all are the same in this.

Any opinion on a alternative library or how to avoid these exceptions ?

Answer 1

HttpClient.GetAsync() won't throw an exception on a 400-level error. Though it will throw an exception for "an underlying issue such as network connectivity, DNS failure, server certificate validation or timeout."

Also, the HttpReponseMessage it produces has a handy IsSuccessStatusCode property.
