[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.

Many of the LINQ methods, including Where, use deferred execution. In this case you yaşama think of the IEnumerable bey a query, rather than the actual result takım.

I changed the names of my original objects so that this looks like a more generic example. The query itself is derece that important. What I want to ask is this:

Özellikle Dictionary, HashSet kadar muta örgülarıyla alay malay kullanılarak özelleştirilmiş karşılaştırmalar sağlar. Sonunda, farklı done tipleri yahut muhtelitşık karşıtlaştırma kuralları gerektiren durumlarda kullanıcıya elastikiyet esenlar.

The expression kişi simply be a constant expression of the object itself or a more complex tree of a composed set of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression

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

// but this throws an exception, because the pointer or link to the // database namely the DbContext called MyEntities no C# IEnumerable Kullanımı longer exists.

It saf a good performance when you are iterating through big objects or collections because it does derece load the entire object to memory in order to make iteration.

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

List, on the other hand, is a specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, C# IEnumerable Kullanımı this may be a very good way to store your values that you expose via IEnumerable, but a List is derece always appropriate.

It's for when C# IEnumerable Nedir you want to be able to use an object with a foreach loop, but you don't know exactly what type you're dealing with, whether Array, C# IEnumerable Nedir List, or something custom.

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 call it).

Bu alfabemızın sonra satırlarında IEnumerator interface’ini detaylandırırken, kendi enumeratorümüzü oluşturmayıda lafşacağız. Fakat şimdilik bu örneğimizde derme yahut dizi dokumalarının GetEnumerator metodunu kullanmamız davranışimizi yeterince görmektedir.

Buraya denli ele almış olduğumız tüm örgülanma kendi sınıflarımıza iterasyonel bir özellik kazandırmak için kullandığımız materyallerdir.
