Custom Collections

[James T.]

Hello!

I defined a custom collection class that inherits from CollectionBase, it
works fine...

Now, I would like to add each item an ID property, so I could access items
in the collection by ID. What I need is a sample how I can generate unique
ID each time when a new Item is added to the collection?

Thanks!

James

How about running a int TotalItemAdded private field?

private int TotalItemsAdded

public Add( object o )
{
o.ID = "item_" + TotalItemsAdded.ToString();
//Add item
TotalItemsAdded++;
}

Note that nothing decrements TotalItemsAdded.

Guid guidID = Guid.NewGuid();
