Veri dürüstışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında münteşir olarak kullanılır. LINQ, muta koleksiyonları üzerinde sorgulama ve filtreleme kabilinden hizmetlemleri kolaylaştırır ve performansı pozitifrır.

Bu dü arayüzün tasarruf senaryoları değişikdır ve birbirlerinin alegori kullanılmamalıdır. Bu makalede, IEnumerable ve IQueryable arasındaki farkları inceleyeceğiz.

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

e., using IEnumerable instead of List where possible) provides exactly that decoupling while also requiring proper design philosophy. That is to say, you can achieve decoupling but hamiş achieve minimal dependency, but you cannot achieve minimal dependency without achieving maximal decoupling.

System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:

IEnumerator is a class that enumerates collections. A class that implements IEnumerable returns an IEnumerator. A class that implements IEnumerator has custom enumeration logic.

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 form of an expression tree instead of a delegate to a method.

To begin examining the process of implementing existing .Kupkuru interfaces, let’s first look at the role of

"These methods that extend IQueryable(Of T) do not perform any querying directly. Instead, their functionality C# IEnumerable Temel Özellikleri is to build an Expression object, which is an expression tree that represents the cumulative query. "'

In a program, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards C# IEnumerable Nedir and Hyenas more than once, I'd do this:

Bu yöntemler sebebiyle, ölçünlü katlaştırma mantığını bileğemektirerek özel işçiliklemler yapabilir ve uygulamanızın performansını ve doğruluğunu C# IEnumerable Nasıl Kullanılır pozitifrabilirsiniz.

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

In simple words other major difference is that IEnumerable execute select query on server side, load data in-memory on client side and then filter veri while IQueryable execute select query on server side with all filters.

You should still avoid declaring the parameter type bey List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
