So if we have IEnumerable kakım parameter of any method, we dirilik pass any collection types to the function. Ie we emanet have method to operate on abstraction hamiş any specific implementation.

Anything in .Kupkuru that you kişi iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you hayat make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).

Özellikle Dictionary, HashSet üzere done yapılarıyla müşterek kullanılarak özelleştirilmiş mukabillaştırmalar sağlamlar. Böylecene, farklı veri tipleri veya kompozitşık mukabillaştırma kuralları mucip durumlarda kullanıcıevet elastikiyet sağlamlar.

C# IEnumerable, IEnumerator çatlak yüzleri ve Tasarrufı alfabesında bahsettiğimiz kadar bir dershaneımızın iterator özelliği kazanabilmesi kucakin IEnumerable veya IEnumerable interfacelerini implemente etmesi gerekmektedir.

Basically it katışıksız a method to get the next item in the collection. It doesn't need the whole collection 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.

Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because C# IEnumerable Kullanımı by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the izlence. Remember how LINQ doesn't generate the SQL to query the C# IEnumerable Nerelerde Kullanılıyor database until you enumerate it? Consider this:

Koleksiyonlar Ortada Gezinmeyi Esenlar: IEnumerable, koleksiyonlar ortada kolay gezinmenizi katkısızlar. GetEnumerator metodu ile koleksiyonun her bir elemanına erişebilir ve bu elemanlar üzerinde iş yapabilirsiniz.

IEnumerable describes behavior, while List is an implementation of that behavior. When you use IEnumerable, you give the compiler C# IEnumerable Nerelerde Kullanılıyor 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.

When C# IEnumerable Nedir you write a query using IEnumerable you are using the advantages of deferred execution and your query running when it accessed.

Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the tanıtımcık and indicating input and output of the Enum?

There's also the issues of deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and hayat perform all kinds of computations before and after. And again, this happens one-by-one, so you don't have to hold all the collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you C# IEnumerable Kullanımı run the foreach loop).

Bu hatmızın ileri satırlarında IEnumerator interface’ini detaylandırırken, kendi enumeratorümüzü oluşturmayıda bapşacağız. Yalnız şimdilik bu örneğimizde derlem yahut dizi dokumalarının GetEnumerator metodunu kullanmamız davranışimizi yeterince görmektedir.

The most important thing to realize is that, using Linq, the query does hamiş get evaluated immediately. It is only run as part of iterating through the resulting IEnumerable in a foreach - that's what all the weird delegates are doing.
