Jan,
I readed this sometime ago. I remember that the more important thing for
this is make some validations when put 1 item in the list. 1 very simple
Example:
public enum ItemType { Type1, Type2, Type3 }
public class Container
{
private long id;
private string name;
private ItemType allowedType;
private IList<Item> listItem;
public long Id { get; set; }
public string Name { get; set; }
public ItemType AllowedType
{
get;
set
{
if (listItem.Count == 0) { allowedType = value; }
}
}
public IList<Item> ListItem { get { listItem.AsReadOnly(); } set; }
public void AddItem(Item item) {
if( item.ItemType.Equals( allowedType) ){
listItem.Add(item);
}
}
}
public class Item
{
private long id;
private string name;
private ItemType itemType;
public long Id { get; set; }
public string Name { get; set; }
public ItemType ItemType { get; set; }
}
Something like this. What is the better way for do this??
Is better but this validation on Business Layer?
