c# - Does more specific exception handling improve performance? -

-

if can catch more specific exception prevent clr doing work , benefit performance wise ? if know might socket exception not care handling differently other exception better still have more specific catch ? working on microframework small improvements in performance , resources worth asking about.

 catch (system.net.sockets.socketexception netex)             {              }   catch (exception ex)             {              }

i not think in terms of performance.

from code correctness perspective: should catch specific exception can.

when catch exception exception handler swallow any exception if not prepared handle it. imagine argumentnullexception thrown. catch block swallow , cause confusion.

if prepared handle socketexception catch that. if less performant it. code correctness not sacrifice such miniscule performance gain*

* or no performance gain @ - almost there zero execution time performance implication @ all. did benchmark on computer , performance more or less equal. not comprehensive test enough confirm instinct. can run own benchmark using technique similar this one

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

-
i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
