How do I get around Inconsistant accessibilty error in C # ?

How do I get around Inconsistant accessibilty error in C # ?

I need to pass a pointer to a node in a linked list to a method.
When I do, I get a "Compiler Error CS0051"

Example
The following sample generates CS0051:

Copy Code
// CS0051.cs
public class A
{
// Try making B public since F is public
// B is implicitly private here
class B
{
}

public static void F(B b) // CS0051
{
}

public static void Main()
{
}
}

That is a simple example. The actual program is a bit more complicated. I am actually using a node in a linked list to pass to the method
LinkedListNode<LevelNode> node

The method uses recursion because the node is mart of a huge linked list structure of linked lists that outputs an xml file.
Either I have to find a way to use recursion without using methods or I need to find a way to pass pointers nodes or actual nodes.
