C# Member Access from Nested Class to Containing Class

Hope that helps Put simply, you'll need a reference to an instance ClassA within ClassB.
C#'s nested classes work differently from Java's, if that's what you're used to. The closest analog would be Java's static class when applied to a nested type (meaning that C#'s nested classes are not associated with a particular instance of the outer class).

I wish this help you You must turn on compiler warnings and pay attention to them. In this case, the compiler is able to pinpoint the exact error in:
code :
 Inner(Outer *parent){}
warning: unused parameter 'parent' [-Wunused-parameter] In constructor 'Outer::Outer()':
 void print(){std::cout<< parent-> data <<std::endl;}
Inner(Outer *parent) : parent(parent) {}
18:7: warning: 'Outer::data' will be initialized after [-Wreorder]
15:10: warning: 'Outer::Inner* Outer::obj' [-Wreorder]
21:1: warning: when initialized here [-Wreorder]
Outer::Outer(): obj(new Inner(this)), data(99) {}

Hope that helps
Is this a bug in gcc? Or does c++ have different access rules for template member function to access nested classes?
code :
prog.cc:8:30: error: 'int Enclosing::Nested::y' is private within this context
         std::cout << t << n->y;  // OK? Why?
                           ~~~^
