I have a class Cars and class Models. Car has many properties such as CarId and List<Models>. Models has has various properties such as ModelID, Color, Make. I have one list of Cars(coming from end user) call is A and then I have few sets lists of Cars(from DB) call it B . A has one list of Car where as B has multiple lists of Car, I want to compare these two including Models too.
I tried using Except but that does not seem to be working
Sorry for not being clear. lets say
list A has item carId = 1 and property Model has two items 1: ModelId =1, color = black, make = 1999 and items 2: ModelId =3, color = white, make = 2004
list B has 2 items
carId = 5 and Model has two items 1: ModelId =2, color = blue, make = 2000 and items 2: ModelId =3, color = white, make = 2010
carId = 7 and Model has two items 1: ModelId =5, color = black, make = 1999 and items 2: ModelId =9, color = grey, make = 2011
in above example bolded values should be produced by comparer which I will store into new list.
appreciate help.
thanks!
I think you want to implement the IEqualityComparer, to add a custom compare function to your Models class
