Bilgi temizışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında münteşir olarak kullanılır. LINQ, veri koleksiyonları üzerinde sorgulama ve filtreleme kabilinden işlemleri kolaylaştırır ve başarımı artırır.
If you çekim to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.
Genel olmayan bir koleksiyon üzerinde çarpık çurpuk bir yinelemeyi destekleyen bir numaralandırıcıyı kullanıma sunar.
Katışık fonksiyonlarının özelleştirilmesi ve veri mimarilarında başarımı çoğaltmak sinein GetHashCode yöntemi kullanılır.
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 ?
but if you "spoof" the enumerator into an enumerable, the second sequence will be empty. Or if you do them in parallel - just bizarre. And there are
The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the C# IEnumerable Nedir form of an expression tree instead of a delegate to a method.
The constructor is not responsible for returning veri to the caller. 2-We need to call a method that returns the cars array. That is in a real-world case, a method that returns an array should be coded in Garage and it should return an array, in which case, there would be no need to use IEnumerable.
but this violates the IEnumerable semantics and the time came when I got wrong results. so switched to orderly creating a fresh iterator instance (see my answer)
This works for read-only access to a collection that implements that IEnumerable hayat be used with a foreach statement.
It's for when you want to be able C# IEnumerable Temel Özellikleri to use an object with a foreach loop, but you don't know exactly what type you're dealing with, whether Array, List, or something custom.
sanarak sorarsak eğer üst satırlarda bahsettiğimiz kadar o sınıfın geriye IEnumerator nesnesi dönen GetEnumerator adlı metodu çitndırıyor olması demekti. Ee haliyle IEnumerable interface’i dayalı sınıfa uygulanmış olduğunda C# IEnumerable Kullanımı GetEnumerator metodunu implement edecektir.

Unfortunately IEnumarable seems to be blindly used birli the lowest interface which C# IEnumerable Kullanımı now causes problems with asynchronous data manipulation (e.
The most important thing to realize is that, using Linq, C# IEnumerable Kullanımı the query does not get evaluated immediately. It is only run kakım part of iterating through the resulting IEnumerable in a foreach - that's what all the weird delegates are doing.
