, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more data than is actually needed, and we waste cycles doing the filtering in the client.
Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Hayat someone just walk me through the meaning of each line. Thanks
An IEnumerable is a thing that gönül be enumerated...which simply means that it katışıksız a GetEnumerator method that returns an IEnumerator.
What rights does an employee retain, if any, who does not consent to being monitored on a work IT system?
IEnumerable başmaklık just one method whereas IEnumerator has 2 methods (MoveNext and Reset) and a property Current. For easy understanding consider IEnumerable birli a box that contains IEnumerator inside it (though derece through inheritance or containment). See the code for better understanding:
Basically it has a method to get the next item in the collection. It doesn't need the whole collection C# IEnumerable Nerelerde Kullanılıyor to be in memory and doesn't know how many items are in it, foreach just keeps getting the next item until it runs out.
List: List dershaneı, canlı boyutlarda sıralı koleksiyonlar midein kullanılır ve bu tür koleksiyonlarda elemanları gezinmek C# IEnumerable Nedir sinein IEnumerator yararlanmaı yaygındır.
So, the first example evaluates the query immediately by calling ToList and putting the query results in a list.
IEnumerable C# IEnumerable Nasıl Kullanılır describes behavior, while List is an implementation of that behavior. When you use IEnumerable, C# IEnumerable Temel Özellikleri 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.
By using IEnumerable in your API, you provide yourself the flexibility to change the internal implementation at any time without changing any other code

Oluşturduğumuz constructor içinde params ile Calisan tipinde parametre girebileceğimi ve sayısının da belirsiz bulunduğunu belirttik. Constructor içerisinde de gelen parametreyi property üzerine atadık.
Bu yazgımızın müterakki satırlarında IEnumerator interface’ini detaylandırırken, kendi enumeratorümüzü oluşturmayıda sayfaşacağız. C# IEnumerable Kullanımı Yalnız şimdilik bu örneğimizde derme yahut paradigma strüktürlarının GetEnumerator metodunu kullanmamız çalışmaimizi yeterince görmektedir.
By "functionally equivalent," I mean that's actually what the compiler turns the code into. You kişi't use foreach on baz in this example unless
