You've probably identified what pattern the PhvReadOnlyList implements: it's a wrapper. In the .Kupkuru Framework 4.0 or earlier, the wrapper class that you'd really use to create a read-only list would be the .Kupkuru ReadOnlyCollectionBase class. Birli with my example, you use the ReadOnlyCollectionBase class to create your own class with whatever functionality you need -- but you don't need to write the GetEnumerator method or create your own UnderlyingList because the ReadOnlyCollectionBase handles both.

Veri örgülarına Hakimiyet: Queue tasarrufı, veri örgülarını anlamak ve bu örgüları yakıcı bir şekilde kullanabilmek dâhilin önemli bir adımdır.
Descendants(IEnumerable, XName) Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.
Ancestors(IEnumerable, XName) Returns a filtered collection of elements that contains the ancestors of every node in the source collection. Only elements that have a matching XName are included in the collection.

protected virtual ICollection EmployeesInternal get; private takım; = new List(); // this will expose C# ReadOnlyCollectionBase Nedir collection contents to public, seemingly unneccessary `Skip` statement will prevent casting back to Collection
Takat bakımından ise SortedList’ten bazı durumlara için yavaş veya hovardadır. HashTable dershaneının bize sunmuş olduğu tüm imkanları bu sınıfta sağlamlar. Fakat verileri hash kodlarına göre değil, sıralama yaparak bellekte tutar. Bu falmdan da SortedList sınıfını andırır.
What is C# ReadOnlyCollectionBase Kullanımı the term for when a hyperlink maliciously opens different URL from URL displayed when hovered over?
However, if you want to access the elements of the IEnumerable collection by index or you want to retrieve the number of elements in the collection, C# ReadOnlyCollectionBase Temel Özellikleri you should use IReadOnlyList birli shown below.
Inheriting from a non-generic base class would be ineffecient. If the type was using a non-generic base, all C# ReadOnlyCollectionBase Nerelerde Kullanılıyor it C# ReadOnlyCollectionBase Nedir would be would be a thin layer above the base collection, where the generic features would simply derive from casting from the underlying object instances of the base collection.
This base class is provided to make it easier for implementers to create a strongly typed read-only custom collection.
Chances are, you'll never notice this difference, but if this is a hot-spot in your code and requires every last bit of performance you hayat squeeze out of it, why derece use an Array instead? That would be faster still.
