c# - Testing for Dictionary KeyNotFoundException -

-

i have scenario there dictionary might or might not have key value @ given time. presently testing see if value exists in following manner, know if best approach or if there better approach handling this.

int myint;  try {     myint = {value dictionary}; } catch {     myint = 0; }

any input? thanks.

take @ dictionary's trygetvalue method

  int myint;   if (!_mydictionary.trygetvalue(key, out myint))   {       myint = 0;   }

a couple of people have suggested using containskey. not idea if want value because mean 2 lookups - e.g.

if (_mydictionary.containskey(key)) // 1 {  myint = _mydictionary[key]; // 2 }
