asp.net - "List.Remove" in C# does not remove item? -

-

hello how can remove item generic list here code im trying right dont know make mistake;/

users us_end = new users(); foreach (var variable in ((list<users>)application["users_on"])) {     if(variable.id == (int)session["current_id"])     {         us_end.name = variable.name;         us_end.id = variable.id;         us_end.data = variable.data;     } } list<users> = ((list<users>)application["users_on"]); us.remove(us_end); application["users_on"] = us;

you have same object remove, not copy.

users us_end;  foreach (var variable in ((list<users>)application["users_on"])) {     if(variable.id == (int)session["current_id"])     {        us_end = (users)variable;        break;     } }  if (us_end != null) {     list<users> = ((list<users>)application["users_on"]);     us.remove(us_end);     application["users_on"] = us; }

edit:

just clarify address here, pst pointed, implement iequatable interface , overridings on groo's answer make work, think it's overkill on specific subject. giving common practice, making clear it's possible remove items list, if diferent instances or diferent objects technique that.
