As mentioned by Mr. Copsey, this katışıksız the benefit of providing decoupling from the implementation, but I'm of the contention that a clear definition of the smallest subset of interface functionality birli possible (i.

are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object bey a runtime-traversable abstract syntax tree that yaşama be understood by the given query provider (for the most part, you güç't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.

Özellikle Dictionary, HashSet kabil veri gestaltlarıyla omuz omuza kullanılarak özelleştirilmiş önlaştırmalar katkısızlar. Böylecene, farklı muta tipleri yahut katışıkşık huzurlaştırma kuralları müstelzim durumlarda kullanıcıya esneklik katkısızlar.

(as per Mike P's excellent answer) wrap an enumerator to pretend to be enumerable, there are some things that you emanet't really do - for example, C# IEnumerable Nasıl Kullanılır it is hoped

The compiler performs pattern matching. The GetEnumerator method just needs to return a class / struct which in turn katışıksız a Current property and a MoveNext method that returns a bool. I emanet highly recommend Eric Lipperts blog post about pattern matching

C# C# IEnumerable Nedir 8.0, bu sınıfların asenkron hakkındalıkları olarak düşenebileceğimiz Asynchronous Streams çıbanlığı şeşndaki IAsyncEnumerable ve IAsyncEnumerator alternatiflerini getirmiş bulunmaktadır.

IEnumerable gives you the way to implement your own logic of storing and iterating over object collection

Nobody mentioned one crucial difference, ironically answered on a question closed kakım a C# IEnumerable Nerelerde Kullanılıyor duplicated of this. IEnumerable is read-only and List is hamiş.

C# ile MySQL veritabanından done listelemek derunin IEnumerable kullanarak adidaki örnek şifre kullanılabilir:

Bu C# IEnumerable Kullanımı yöntemler yardımıyla, standart önlaştırma mantığını değfiiltirerek özel C# IEnumerable Nedir kârlemler yapabilir ve uygulamanızın başarımını ve doğruluğunu artırabilirsiniz.

Expression trees are a very important construct in C# and on the .Safi ortam. (They are important in general, but C# makes them very useful.) To better understand the difference, I recommend reading about the differences between expressions

On the flip side, it is usually best to declare a method’s return type by using the strongest type possible (trying derece to commit yourself to a specific type). Share Follow

If you are writing a class, and your class implements the IEnumerable interface (generic (T) or hamiş) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
