c# - Try-Catch Exception abuse -

i have found code this:

try  {     myclass.do().tostring(); } catch () { } 

which results in exception being thrown when do() returns null. could, instead, use

(myclass.do() ?? "").tostring(); 

to avoid exception being thrown. see code this:

for (int = 0; < x.length; i++) {     if (x.phases[i].num == activenum)     {         try         {            result = x.phases[i + 1].obj;         }         catch (exception ex) {  }     } } 

i think not practice. however, can't find references support ideas.

i tried search on web, did not have luck. of references or documentation meant c++ or java.

will please me justify idea strong reference, or enlighten me if previous approaches above in fact acceptable.

you're correct: using exceptions purposes of flow control bad practice. referred anti-pattern reason.

you can find detailed explanation here. while article references java , c++, anti-pattern in c# same reasons.

for c#/.net specific explanation, see msdn article.
