Some operations of the C # list (whether the two list elements want to be the same, whether the list is contained in another list)

First, the fake has two List<t> objects, List1 and List2, the following method to determine whether two list is equal

List1.all (list2.contains) && List1.count = = List2.count

Second, how to determine whether the list in C # is complete with another list

BOOL Iscontainsall (list<class> ListA, list<class> listb) {    return listb.all (b = Lista.any (A = a.equal (b)));

If the list contains standard data types, it is easier to change a.equal (b) to a==b.
