I am writing a get(T element) method for a QuadTree. In Java I usually returned null if the element can not be found, but in C# I cannot do that because it says T could be a non-nullable value type. I don't want to return default(T) because I want to be able to check if the returned value is null in order to see if it found the object or not. Does anybody know of a good way to do this?
