c# - Is it necessary to free objects in final block of try-catch block? -

the question self explanatory :

foo objfoo; try {   objfoo = new foo();   ..........   ......... } catch {  } {   objfoo = null; }  

is necessary free objects ?

note: setting local / field null not freeing value. instead removing reference value may or may not make elligable collection during next gc cyle.

to answer question, no not necessary. jit`er calculate last time local used , remove local 1 of object's gc roots @ time. nulling local out not speed process.
