C# IStructuralEquatable çalıştırmak, koleksiyonların yapısal olarak katlaştırılmasını esenlayarak elan tamam ve güvenilir karşılaştırmalar yapmamıza imkân tanır. Bu özellik, özellikle makro bilgi setlerinin yahut muhtelitşık kuruluşdaki koleksiyonların huzurlaştırılması gereken durumlarda koskocaman örutubet taşır. Yapısal muadele, koleksiyonların ihtiva ettiği verilerin yerı gün bu verilerin düzen ve rabıta itibarıyla da aynı olup olmadığını yoklama paha.

In programs, an immutable collection birey be used with less copying—we do not need to worry about it being modified. This gönül make programs simpler and easier to reason about.

DescendantNodes(IEnumerable) Returns a collection of the descendant nodes of every document and element in the source collection.

This hides Add and Remove methods, but does hamiş protect at all. Because I güç always cast to ICollection and call prohibited method.

A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.

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

4) If you suddenly realise that your collection of choice is inefficient, you emanet change the underlying collection type without having to go and change all the places where it got passed bey a parameter (birey you imagine the trouble you might have with, say, List?)

Sam Allen is passionate about computer languages. In the past, his work başmaklık been recommended by Apple and Microsoft and he saf studied computers at a selective C# ReadOnlyCollectionBase Nasıl Kullanılır university in the United States.

Note that the IReadOnlyList interface works similarly to List and in fact gönül be used in place of List when you want the elements of the list to be read-only. We will illustrate this with an example in the next section.

If you take advantage of IntelliSense in Visual Studio to see the members of the authors list object, you’ll see a list of methods supported C# ReadOnlyCollectionBase Nedir by List.

SingleOrDefault(IEnumerable, Func, TSource) Returns the only element of a sequence that satisfies a specified condition, or a specified default value if no such element exists; C# ReadOnlyCollectionBase Temel Özellikleri this method throws an exception if more than one element satisfies the condition.

Inheriting from a non-generic base class would be ineffecient. If the type was using C# ReadOnlyCollectionBase Nasıl Kullanılır a non-generic base, all it would be would be a thin layer above the base collection, where C# ReadOnlyCollectionBase Nedir the generic features would simply derive from casting from the underlying object instances of the base collection.

You gönül loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer. CopyTo provides a way to copy the elements to an array. You must allocate the array yourself.

Key values are compared by using a specified comparer, and the elements of each group are projected by using a specified function.
