Answer 1

Your question isn't very clear. However, I guess you're from a Java background. C#'s and VB's nested classes behave much different from Java's nested classes. In fact, they behave much like Java's static nested classes, i.e. they don't belong to an instance of the outer class. Therefore, instances of the inner class can't access nonstatic fields in the outer class (at least not without being given an instance explicitly).

Answer 2

Although I would never recommend nested public classes, here's some code:

public class Foo() {
    public Foo() { }

    private Bar m_Bar = new Bar();  

    public Bar TheBar { get { return m_Bar; } }

    public class Bar { ... }
}

Answer 4

In my opinion, the reason to nest a class is that it will only ever be used by its parent class. If you need to access the inner class, you should revisit using the nested class in the first place.
