If an airline is "countable", this means that there MUST be a flight attendant present on the plane, whose sole job is to count:
Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Emanet someone just walk me through the meaning of each line. Thanks
g. executing SQL on GarbageCollected contexts). I would say that ICollection is every thing you said apart from the "lazy evaluation" and we should be using that, especially if the data katışıksız already been enumerated once!
e., using IEnumerable instead of List where possible) provides exactly that decoupling while also requiring proper design philosophy. That is to say, you güç achieve decoupling but not achieve minimal dependency, but you cannot achieve minimal dependency without achieving maximal decoupling.
Sonunda burada ortaya çıkan sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator adlı metot implement ettirilmektedir. IEnumerator ise ait sınıfa iterasyon teamülleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesuliyetli olacaktır.
Quoting that article, 'As per the MSDN documentation, calls made on IQueryable operate by building up the internal expression tree instead.

This way you have possibility to do many things with that query without touching the data (in this case veri in the list). List method takes the prepared query and executes it against the source of veri.
Güç a unique position be deduced if pieces are replaced by checkers (emanet see piece color but derece type)
List, on the other hand, is a specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, this may be a very good way to store your values that you expose via IEnumerable, but a C# IEnumerable Temel Özellikleri List is hamiş always appropriate.
IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get veri from database. Share Follow
means that "var myResult" contains all elements from myEnumerableList, only when this C# IEnumerable Temel Özellikleri element (here, called 'u')özgü a property userId that is equal to "Yusuf"
IQueryable is a very powerful feature that enables a variety of interesting deferred execution scenarios (like paging and composition based queries).
Below C# IEnumerable Temel Özellikleri mentioned small test might help you understand one aspect of difference between IQueryable and IEnumerable. I've reproduced this answer from this post where C# IEnumerable Nerelerde Kullanılıyor I was trying to add corrections to C# IEnumerable Nerelerde Kullanılıyor someone else's post
