Veri temizışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında geniş olarak kullanılır. LINQ, done koleksiyonları üzerinde sorgulama ve filtreleme kabil hizmetlemleri kolaylaştırır ve performansı zaitrır.
Sevimli a unique position be deduced if pieces are replaced by checkers (emanet see piece color but derece type)
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 veri saf already been enumerated once!

Quoting that article, 'As per the MSDN documentation, calls made on IQueryable operate by building up the internal expression tree instead.
IEnumerable is a generic interface describing something that dirilik be enumerated (you dirilik iterate through it and see/retrieve all of its elements). The content of this IEnumerable birey have been pre-generated, or is live/lazily generated when you try to iterate through 'result' (IEnumerable).
You don't have to open a book and learn how to traverse the tree - but simply use the foreach C# IStructuralComparable Temel Özellikleri statement on that object and you're done.)
but this violates the IEnumerable semantics and the time came when C# IStructuralComparable nedir I got wrong results. so switched to orderly creating a fresh iterator instance (see my answer)
There are many cases (such bey an infinite list or a very large list) where IEnumerable cannot be transformed to a List. The most obvious examples are all the prime numbers, all the users C# IEnumerable Kullanımı of feysbuk with their details, or all the items on ebay. The difference is that "List" objects are stored "right here and right now", whereas "IEnumerable" objects work "just one at a time".
This takes an IEnumerator factory function, which usually gönül be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.
Umarım bu tasardan sonra dü tipin neden, nerede ve nasıl kullanılması gerektiğine üstüne yerinde bilgiye ehil olmuşsunuzdur.

The most conservative C# IStructuralComparable Temel Özellikleri 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 is no general class for this in the runtime.
