Implementation of IEnumerable is generally the preferred way for a class to indicate that it should be usable with a "foreach" loop, and that multiple "foreach" loops on the same object should operate independently.

I noticed that if I use IEnumerable, when I debug and inspect "yığın", which in that case is the IEnumerable, it başmaklık some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.

IEnumerable interface’i sebebiyle bir dershane itere edilebilir özellik kazanmaktadır. Peki bir dershaneın itere edilebilirlik özellik kazanması neydi?

The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are hamiş explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.

Nihayetinde burada ortaya çıhun sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isimli metot implement ettirilmektedir. IEnumerator ise ilişkin sınıfa iterasyon aksiyonleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesul olacaktır.

Örnekte, kullanıcıların müsavi olup olmadığını muayene ederken kullanıcı adları dikkate alınmıştır.

So, the first example evaluates the query immediately by calling C# IEnumerable Temel Özellikleri ToList and putting the query results in a list.

"These methods that extend IQueryable(Of T) do hamiş perform any querying directly. Instead, their functionality is to build an Expression object, which is an expression tree that represents the cumulative query. "'

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

And that might be useful and more efficient in certain cases. For example, your class might hamiş hold any collection in memory, but C# IEnumerable Kullanımı rather iterate over all files existing in a certain directory, or items in certain DB, or other unmanaged resources. IEnumerable dirilik 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).

a reset on enumerators, but this is largely a design mistake and shouldn't be used (it is even a formal requirement in the spec that iterator blocks throw an exception if you C# IEnumerable Nerelerde Kullanılıyor call it).

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement.

Siz de C# IEnumerable Nedir benim kabilinden çeşitli .Safi platformlarında çeşitli icraat geliştirdiyseniz ve kullandığınız classların arkasındaki mimariyi kaygı ediyor,eliniz her seferinde F12’ye gidiyorsa :) IEnumerable ve IEnumerator interfacelerine birbunca defa yorgan gelmiş,ve gine siz bile benim üzere o gücük teşhismlar ile yetinememiş olmalısınız.Ozaman hiç lafı uzatmadan gelelim konuya.
