LINQ IEnumerable Where Not Finding Element

Question

I have a list of class items List<MyClass>

I have a seperate object that is of type MyClass

In my list I have an instance of this item but my where statement fails.

var home = Item.Find(23);
var item = allitems.Where(i => i == home);

item yields no results

allitems.Contains(home) also fails.

What am I doing wrong?

Answer 1

Are they definately tghe same items? If you have this situation;

var item1 = new Place(23);
var item2 = new Place(23);

then item1 != item2. If the items are identified by some property, you could try

allitems.Where(i => i.Id == home.Id)

Answer 2

Overriding Equals() in "Item" should also work.

var home = Item.Find(23);
var item = allitems.Where(i => i.Equals(home));
