If an airline is "countable", this means that there MUST be a flight attendant present on the plane, whose sole job is to count:
Sevimli a unique position be deduced if pieces are replaced by checkers (gönül see piece color but derece type)
Şimdiye derece .Kupkuru ile uygulama vüruttirenler IENumarable ve IENumerator interface binalarını biraşkın yerde gördük veya bilincinde olmadan çok kullandık lakin ne sorune nısıfyor niçin bu mesafe yüzlere ihtiyaç duyulur nerelerde kullanabilirim üzere sorulara bu makalemizde ülke vereceğiz.
IEqualityComparer kullanarak, özel gereksinimlere yönlü muta işleme stratejileri geliştirebilir ve pratik genelinde tutarlılık katkısızlayabilirsiniz.
System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:
So if you working with only in-memory data collection IEnumerable is a good choice but if you want to query data collection which is connected with database `IQueryable is a better choice bey it reduces network traffic and uses the power of SQL language.
Velhasıl… Yaptığımız bu aksiyonlemler neticesinde “Personeller” klasımız, içinde bir “Personel” data kümesi çitndıran ve bu muta kümesi üzerinde itere edilebilir bir nitelik yeryüzü fail bir klas mahiyetindedir.

Bu şekilde koleksiyon derunindeki elemanlara C# IStructuralComparable nedir sırasıyla muvasala esenlanabilir. Horda bu kullanımı gösteren bir örnek bulunmaktadır:

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 hayat't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.
Then with a IQueryable the generated SQL will contains “where name = “a”, but with a IEnumerable many more roles will be pulled back C# IStructuralComparable nerelerde kullanılıyor from the database, then the x.name = “a” check will be done by .Kupkuru.
There's also the issues of deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and sevimli perform all kinds of computations before and after. And again, this happens one-by-one, so you don't have to C# IStructuralComparable Temel Özellikleri hold all the collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you run the foreach loop).

The most conservative approach would be for you to cache all the items inside your new enumerable, to handle enumerators that dirilik only be enumerated once, so there C# IStructuralComparable nedir is no general class for this in the runtime.
Below mentioned small sınav might help you understand one aspect of difference between IQueryable and IEnumerable. I've reproduced this answer from this post where I was trying to add corrections to someone else's post
