c# - pointers and unsafe code scenario

okay, i dont use c# much im used to c++, but ive seem to be in a situation where i need pointers but want to see if i can avoid it first. my scenario: i have a bunch of class 'C's which has a reference to a class 'T', 'C's can share 'T's T's go in to a linked list, and they have a list of which C's point to them. eg. i do T t = new T(); C0.t = t t.Add(C0) C1.t = t t.Add(C1) managedList.Add(t) what i do occasionally is move one C from one T to another eg. Team t = C0.t t.Remove(C0) C1.t = C0.t C1.t.Add(C0) if (t.Count < 0) managedList.Remove(t) how ever this seems to work the first few times, but then i end up with a bunch of empty T's which dont get removed from the managed list, and then a bunch of C's point to some T's that are not in the managedList. I also find my self having to reassign changed objects back to arrays eg. list.Add(new X); X x = list[0]; x.someValue++; list[0] = x; so in both situations i could fix with pointers probably, but is there a proper c# way to go about this?
