I noticed that if I use IEnumerable, when I debug and inspect "baskın", which in that case is the IEnumerable, it saf some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.
I changed the names of my original objects so that this looks like a more generic example. The query itself is derece that important. What I want to ask is this:
There are many differences but let us discuss about the one big difference which makes the biggest difference. IEnumerable interface is useful when your collection is loaded using LINQ or Entity framework and you want to apply filter on the collection.

" C# IEnumerable Nedir This is false, because the where clause is getting called on an IEnumerable and that only knows how to loop through objects which C# IEnumerable Nedir are already coming from the database. If you made the return of AllSpotted() and the C# IEnumerable Nedir parameters of Feline() and Canine() into IQueryable, then the filter would happen in SQL and this answer would make sense.

My question is that should these classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.
The first method advances to the next object in the IEnumerable object that created the enumerator, returning false if it's done, and the second returns the current object.
