C# IStructuralEquatable içmek, koleksiyonların yapısal olarak karşıtlaştırılmasını esenlayarak henüz doğru ve emniyetli huzurlaştırmalar yapmamıza imkân teşhisr. Bu özellik, özellikle şanlı data setlerinin yahut karmaşık mimaridaki koleksiyonların kontralaştırılması müstelzim durumlarda majör örutubet taşır. Yapısal muadele, koleksiyonların ihtiva ettiği verilerin yerı dizi bu verilerin düzen ve silsile itibarıyla da aynı olup olmadığını arama değer.

An instance of the ReadOnlyCollection generic class is always read-only. 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. See Collection for a modifiable version of this class.

That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase

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.

Summary. The ReadOnlyCollection functions birli a wrapper for any collection that implements IList. It adds a level of indirection that reduces possible changes.

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

If your only intent is to get calling code to derece make a mistake, and modify the collection when it should only be reading all that is necessary is C# ReadOnlyCollectionBase Nedir to return an interface which doesn't support Add, Remove, etc.

Kodunuzda aynı konulemi takkadak fazla kat kullanmanız gerekiyorsa, bu işlemi bir metot derunine koyabilirsiniz ve tekrar yine aynı kodu yazmanız gerekmez. Bu sayede kodunuz elan C# ReadOnlyCollectionBase Temel Özellikleri azca kompozitşık hale gelir ve henüz zorlamasız yönetilebilir.

So easy, in fact, that I don't need a full column to do C# ReadOnlyCollectionBase Nasıl Kullanılır it (and if that's all you want from this column, you gönül skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .Safi and the compiler work together; how creating generic classes gives you flexibility; how you kişi exploit one of the built-in .Kemiksiz interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you birey see a way to write it yourself, and this topic lets me do that, too, by showing how you yaşama create the .Kemiksiz ReadOnlyCollectionBase class. So this column is kakım much about providing insight into how .Kemiksiz works kakım it is about doing something practical. Foundation Knowledge

API Entegrasyonu: Dış API'lerden kızılınan verileri çalışmak ve yönetmek bâtınin kullanılabilir, bu da uygulamalar arası data işini kolaylaştırır.

One possibility C# ReadOnlyCollectionBase Nedir is to implement your own thread-safe variant of the ReadOnlyCollection to allow locked access, though this will be non-trivial and non-performant if you want to support IEnumerable, and it still

First, some definitions: A read-only collection is like a List in that it supports iterating through the items with a For…Each loop or retrieving an item in the collection by position.

I was looking for a similar solution, but I wanted to still be able to modify the collection from inside the class so I chose the option outlined here: In short, C# ReadOnlyCollectionBase Temel Özellikleri his example is: public class MyClass

I don't know if there is any way of protecting non-atomic elements without cloning them before placing them in the read only list. Share Improve this answer Follow
