c# - Should I re-use a Struct? -
i know structs value types , live on stack, unless declared field in reference type, , contain values in memory @ location. i'm wondering whether or not efficient or worthwhile re-use declared struct in iterated loop rather creating new 1 each time. how costly stack instantiate variables, if @ all? also, related question, if instantiate struct inside method call create local copy of struct or create first parameter of method when executes? about declarations: // worth doing... mystruct ms = new mystruct(0); (int = 0; i< 10000; i++) { ms.num = i; // ms } // ...over this: (int = 0; i< 10000; i++) { mystruct ms = new mystruct(i); // ms } public struct mystruct { public int num; public mystruct(int mynum) { num = mynum; } } and instantiation: for (int = 0; i< 10000; i++) { mymethod(new mystruct(i)); // mystruct live in scope? }
