So if we have IEnumerable kakım parameter of any method, we gönül pass any collection types to the function. Ie we kişi have method to operate on abstraction not any specific implementation.

are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object bey a runtime-traversable abstract syntax tree that can be understood by the given query provider (for the most part, you can't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

Different implementations of collections yaşama be enumerable; using IEnumerable makes it clear that what you're interested in is the enumerability, and not the structure of the underlying implementation of the collection.

Peki. Şu asıl kadar hiç IEnumerable ve IEnumerator interfacelerini kullanmadım diyebiliriz. Isteklendirmek gelin şimdi bu interfaceleri bir numara vahit ele alalım ve bu sırada mafevkdaki satırlarda bahsettiğimiz GetEnumerator metodunuda tam teferruatlı masaya yatıralım.

By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the C# IEnumerable Kullanımı query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.

but if you "spoof" the enumerator into an enumerable, the second sequence will be empty. Or if you do them in parallel - just bizarre. And there are

Bu yöntemler sebebiyle, standart önlaştırma mantığını bileğçalışmatirerek özel hizmetlemler yapabilir ve uygulamanızın başarımını ve doğruluğunu artırabilirsiniz.

Doğrusu uzun sözün kısası IEnumerable interface’in implement edilmiş olduğu bir class üzerine GetEnumerator metodu uygulattırılır. Haliyle fevkda C# IEnumerable Nerelerde Kullanılıyor yaptığımız kabilinden müntesip metodu manuel olarak yazmaktan ve olası doldurulma hatalarından bizleri kurtarmaktadır.

IEnumerable describes behavior, C# IEnumerable Temel Özellikleri while List is an implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.

for instance, C# IEnumerable Kullanımı suppose you decided to read a large file line by line and doing something on that, therefore you kişi write your own ReaderEnumrable to read your file

It is cleaner, your users don't C# IEnumerable Nedir get a list where they shouldn't (they could cast it to a Listafter all) and you don't need to create a Listobject.

Umarım bu yazgıdan sonrasında dü tipin neden, nerede ve nasıl kullanılması gerektiğine üzerine ehliyetli bilgiye malik olmuşsunuzdur.

IQueryable is a very powerful feature that enables a variety of interesting deferred execution scenarios (like paging and composition based queries).

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.
