Why the code give me an error

Question

Hi there
I have this code
public class NodeList : Collection >
{
public NodeList() : base() { }
public NodeList(int initialSize)
{ // Add the specified number of items
for (int i = 0; i ));
}
public Node FindByValue(T value)
{ // search the list for the value
foreach (Node node in Items)
if (node.Value.Equals(value)) return node;
// if we reached here, we didn't find a matching node
return null;
}
}
source :  http://msdn.microsoft.com/en-US/library/ms379572(v=vs.80).aspx
i n visual studio 2010 c# language it gives me an error in
public class NodeList : Collection >
so I change it to I Collection
and then the error jump to base.items , exactly with items
so what is wrong ... it is from msdn.microsoft

The base keyword is used to use the code from the parent class in case of inheritance...
You will need to define the Public class Node<> for this..
You just missed this code from the MSDN link..
public class Node { // Private member-variables private T data; private NodeList neighbors = null; public Node() {} public Node(T data) : this(data, null) {} public Node(T data, NodeList neighbors) { this.data = data; this.neighbors = neighbors; } public T Value { get { return data; } set { data = value; } } protected NodeList Neighbors { get { return neighbors; } set { neighbors = value; } } } }
