c# - Reuse the Same Variable For Multiple TryParse() Calls -


i did reading on this, , questions similar mine, looks ask might not (easily) possible... wanted verify anyway. maybe questions older version of c#/.net, , thing has been implemented recently.

anyway. have switch-case statement in 1 of classes, purpose take int (typeid) , string (value) , check whether value can parsed data type indicated typeid. example, here part of have now:

    case 1:         char charret;         return char.tryparse(value, out charret);     case 2:         regex re = new regex(constants.regex_alphanumeric);         return re.ismatch(value);     case 3:         bool boolret;         return bool.tryparse(value, out boolret);     //and on...

what able avoid char/bool instantiation see in cases 1 & 3. ideally, have return statement. it's not big deal (obviously), nice if make more (even more) compact.

that's inherently impossible.

variables passed out parameters must match parameter type.
