.net - Does c# have inner class extra overhead? -

-

i have following simple class:

class stack {   public class node // inner class   {       string item;       node next;   } }

a stack n items uses: 8 bytes (reference string) + 8 bytes (reference node) + 16 bytes (sync block index + type object pointer). wonder inner class overhead. need add 8 bytes? stack n items uses ~ 40*n bytes or ~32*n bytes?

c# inner classes not have hidden reference instance of outer class java it. if want behavior can create manually. there nothing in c#.

an inner class has different access rules , differently structured name. also, inner classes share generic type parameters of outer class might create overhead. it's organization concept (in c#).
