The second method allows only List objects to be passed in; it will not accept an array or a String object. Obviously, the first method is better because it is much more flexible and yaşama be used in a much wider range of scenarios.

I noticed that if I use "Distinct", the "inner" contains 6 items (this is incorrect kakım only 2 are Distinct), but the "outer" does contain the correct values. Again, probably the delegated methods determine this but this is a bit more than I know about IEnumerable.
Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the izlence. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:
C# C# IEnumerable Temel Özellikleri IEnumerator kullanarak MySQL veritabanından bilgi çkol bu verileri DataGridView denetlemeüne nasıl ekleyebileceğimizi gösteren örnek harf aşağıda mekân almaktadır.

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical veri or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' data if it's able to do so or throw an exception if it kişi't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A C# IEnumerable Kullanımı bit late now to change things, though.
" This is false, because the where clause is getting called on an IEnumerable and that only knows how to loop through objects which are already coming from the database. If you made the return of AllSpotted() and the parameters of Feline() and Canine() into IQueryable, then the filter C# IEnumerable Temel Özellikleri would happen in SQL and this answer would make sense.
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
