Re: Novice question about inherited constructors

Thank you. I am actually trying to figure out why a TreeView works when
nodes are constructed using the TreeNode class but do not work when using a
class derived from TreeNode.

What is the difference between

public class TreeNode
{
public TreeNode()
{
}

}

and

public class B : TreeNode
{
public B : base()
{}

}

?

Why does an index go out of range in LoadViewState with the later.

How is

different from
public class B : A
{
public B() : base()
{}
}

The first declares a type which derives from System.Object
(implicitly). The second declares a type which derives from A. Both
declare a public parameterless constructor which calls (implicitly in
the first case) the parameterless constructor in the base class.
