Only assignment, call, increment, decrement, and new object

Question

var PlayersID ="";

if (res = base.Interact(player))

{

TurnTo(player, 5000);

var getId = GameServer.Database.SelectObjects<DOLCharacters>("RealmPoints > 0 ORDER BY RealmPoints DESC LIMIT 1");

foreach (var t in getId)

{

PlayersID == t.Name;

}

 

 

 

Why am I getting  ?

Only assignment, call, increment, decrement, and new object expressions can be used as a statement
