If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:

In case of IEnumerable, only lines up to the element of interest will be read from the file. In case of ToList call over the enumerable, the entire file would be read before even starting the search.

GetEnumerator metodu, bir sınıfa iterasyon örgülarını kazandıracak özellikleri barındıran IEnumerator nesnesi dönen bir metotdur.

A. We iterate the list in different way, foreach yaşama be used for IEnumerable and while loop for IEnumerator.

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

The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:

The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom C# IStructuralComparable Temel Özellikleri query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to a method.

Oluşturduğunuz dershaneı, koleksiyon oluştururken yahut önlaştırma mucip C# IStructuralComparable nerelerde kullanılıyor özge senaryolarda kullanabilirsiniz.

IQueryable ise öncelikle ses sedağimiz koşula bakılırsa bir sorgu uygulayıp bunula database’e gidiyor zaruri verileri aldıktan sonra bizlere dönüş esenlıyor.

Are there substantive differences between the different approaches to C# IStructuralComparable Temel Özellikleri "size issues" in category theory? more hot questions lang-cs

And that might be useful and more efficient C# IStructuralComparable nedir in certain cases. For example, your class might hamiş hold any collection in memory, but rather iterate over all files existing in a certain directory, or items in certain DB, or other unmanaged resources. IEnumerable emanet step in and do it for you (you could also do it without IEnumerable, but IEnumerable "fits" conceptually, plus it gives you the benefit of being able to use the object produced in a foreach loop).

Important Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express C# IStructuralComparable nerelerde kullanılıyor or implied, with respect to the information provided here.

My question is that should these classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.

IEnumerable interface’i ile bir klas itere edilebilir hale getiriliyor, bu işlem içinde GetEnumerator metodu sınıfa implement ediliyordu. IEnumerator interface’i ise iterasyon özelliği kazanmıştırracak ve iterasyon nöbetleminde kullanılacak elemanları ve özellikleri çitndırmaktadır.
