.Add to a derived class

[rmatthew]

I have a class that has within it subclasses...

 

I am trying to implement a collection of those subclasses as a property of the top most class such that I can utilize a .add() type funcation.

 

such as follows:

 

dim dt as datatable

dt.rows.add(dt.newrow)

 

I would like to use this strucature with my classes

 

I have implemented IEnumerator, IEnumerable etc. and am pretty happy with the results - just need this last little thing :)

 

Help

 

Could be that I am working on little sleep...

You can create a strongly typed collection class (for storing the subclasses) with an add method. Then create a property of that class in the main class.

 

// pseudo code
public class Team
{
	public PlayerCollection Players
	{
		get { return _players; }
		set { _players = value; }
	}
}

public class Player
{
}

public class PlayerCollection : CollectionBase
{
	public void Add(Player obj)
	{
	}
}
