c# - Passing List<int> with more then 10 lac records in function parameter? -

-

i have situation have more 10 lac record in database. , when user hit action method in mvc selected records want check whether these records present in database or not fetching record , comparing them record passed user.

then want pass record function. safe pass many record in function parameter??

here demo :-

    //action method      [httpget]     public actionresult saverecords(list<int> selectedrecords)     {         list<int> allrecordsfromdb = _db.getallrecords();         if(allrecordsfromdb.contains(selectedrecords))         {             _process(allrecordsfromdb); //here passing more 10 lac devices function parameter         }     }      private void _process(list<int> allrecords)     {         //do process here      }

thanks :)

yes safe.

as phil said "as list passing reference list of items , not actual items themselves."

another solution can put records in session or cache(according use-case) , can access anywhere ..no need pass records parameter.
