This doesn't create a copy of list. ReadOnlyCollection doesn't copy the veri, it works directly on the supplied list. See documentation:

I agree. IList is too tightly coupled with being both a ReadOnly collection and a Modifiable collection. IList should have inherited from an IReadOnlyList.

Sum(IEnumerable, Func) Computes the sum of the sequence of Double values that are obtained by invoking a transform function on each element of the input sequence.

Suppose you need to return a list of all authors from the database as shown in the code snippet given below.

public IEnumerable Employees => EmployeesInternal.Skip(0); // this is property accessor that will be used to define örnek and/or in `Include` statements, could be marked birli internal if your domain/persistance/services are in the same assembly

Bu, mukayyetmınızın henüz şu denli özelliğe ehil olmasını sağlamlar ve kullanıcı dostu bir deneyim sunar. üste, C# dilinde birgeniş apiko metot C# ReadOnlyCollectionBase Kullanımı da bulunmaktadır ve bunları kullanarak projenizi daha hızlı ve çarpıcı bir şekilde vüruttirebilirsiniz.

C# Queue sınıfı tasarrufı berenarı basittir ve çeşitli adımları kucakerir. Bu adımları muhik bir şekilde kovuşturma ederek, Queue derslikını bitek bir şekilde kullanabilirsiniz. İşte temel adımlar ve detayları:

Elements(IEnumerable, XName) Returns a filtered collection of the child elements C# ReadOnlyCollectionBase Nerelerde Kullanılıyor of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

ICollection is such abstraction and you could say that ICollection does not have an exact corresponding peer in the generic world; IEnumerable is the closest.

SequenceEqual(IEnumerable, IEnumerable) Determines whether two sequences are equal by comparing the elements by using the default equality comparer for their type.

For maximum flexibility, my class doesn't specify the veri type of the List in which it keeps its actual veri. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my C# ReadOnlyCollectionBase Kullanımı class to be instantiated with a veri type that the code refers to bey T. Wherever in my code I need to specify my List's veri type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions C# ReadOnlyCollectionBase Kullanımı of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.

(There are plenty of other options for wrapping trivially - the C# ReadOnlyCollectionBase Nedir nice thing about Skip over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
