Combining lists but getting unique members
- by MC
I have a bit of a special requirement when combining lists. I will try to illustrate with an example. Lets say I'm working with 2 lists of GamePlayer objects. GamePlayer has a property called LastGamePlayed. A unique GamePlayer is identified through the GamePlayer.ID property. Now I'd like to combine listA and listB into one list, and if a given player is present in both lists I'd like to keep the value from listA.
I can't just combine the lists and use a comparer because my uniqueness is based on ID, and if my comparer checks ID I will not have control over whether it picks the element of listA or listB. I need something like:
for each player in listB
{
if not listA.Contains(player)
{
listFinal.Add(player)
}
}
However, is there a more optimal way to do this instead of searching listA for each element in listB?
