How to reassign a one-time object variable?

Question

In C # when reassigning a one-time object variable with a new object, how does it work in memory? Will the memory space occupied by the old object be simply overwritten by the new object? Or do I still need to call Dispose()to free the resources that it uses?

DisposableThing thing;

thing = new DisposableThing();
//....do stuff
//thing.Dispose();
thing = new DisposableThing();
