Just declare them inside the class. They then go inside the class 
namespace, but are not strictly part of the class instance itself.

e.g.:

class C
{
   enum Enum { one, two, three}
   struct S { int x; int y; }
}

C.Enum e = C.Enum.one;
C.S s = C.S(1, 2);

// can also access the namespace via an instance:
C instance;
instance.Enum e = instance.Enum.one;
