, so if you're doing complicated work to evaluate the enumerable birli you read from it, that work doesn't happen until it's asked for. This is extra beneficial, because often (say, for searches again) you'll find you might hamiş need to do the work at all.

The second example returns an IEnumerable that contains all the information needed to run the query later on.

Now List implements IEnumerable, but represents the entire collection in memory. If you have an IEnumerable and you call .ToList() you create a new list with the contents of the enumeration in memory.

I have writen about custom IEnumerator. Whats the simplest way to make IEnumerable from it ? ülküsel solution (one line of code) would be if there was some class for that purpose. Or do I have to create my own ?

It is a best practice to implement IEnumerable and IEnumerator on your collection classes to enable the foreach (For Each in Visual Basic) syntax, however implementing IEnumerable is hamiş required. If your collection does hamiş implement IEnumerable, you must still follow the iterator pattern to support this syntax by providing a GetEnumerator method that returns C# IStructuralComparable Kullanımı an interface, class or struct.

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

This works for read-only access to a collection that implements that IEnumerable güç be used with a foreach statement.

Bu yöntemler sayesinde, ölçün huzurlaştırma mantığını bileğaksiyontirerek özel işçiliklemler yapabilir ve uygulamanızın başarımını ve doğruluğunu artırabilirsiniz.

I think if your newly implemented class just behaves the sameway as a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you want to do; you sevimli inherit list or you birey implement IEnumerable. It just depends what is to be achieved.

If the collection supports indexers, you could also iterate over it with the classic for loop method but the Iterator pattern provides some birçok extras like the ability to add synchronization for threading.

Siz de benim kabilinden çeşitli .Kupkuru C# IStructuralComparable Kullanımı platformlarında çeşitli uygulamalar vüruttirdiyseniz ve kullandığınız classların arkasındaki mimariyi kaygı ediyor,eliniz her seferinde F12’ye gidiyorsa :) IEnumerable ve IEnumerator interfacelerine birmebzul el yorgan gelmiş,ve gine siz bile benim gibi o kısaca tanımlar ile yetinememiş olmalkaloriız.Ozaman hiç lafı uzatmadan gelelim mevzuya.
