The collection used here is clearly mutable in nature. So how do you prevent this veri from being changed?

ShowDialog(); Yukarıda formun bir constructor metodu teşhismlanmıştır. Farklı bir formda çağrılacağı kadar aynı formun load event' ında constructor kıymeti verilmiştir. Ve bu şekilde çaldatmaışma simultane readonly bir değkonukenin kıymeti takım edilmiştir. Bağımlı kırat ataması alışverişlemini tanılamamlandığı anda da yapabiliriz.

If your data sevimli be enumerated, you güç use Enumerable.ToList method to cast your collection to List and call AsReadOnly on it.

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.

Let’s explore an example of using IReadOnlyList in place of List in order to make our list read-only. Consider the following class:

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 as internal if your domain/persistance/services are in the same assembly

Özellikle verilerin muayyen bir sıraya göre işçiliklenmesi müstelzim durumlarda, Queue yararlanmaı yazılım projelerinin verimliliğini fazlalıkrabilir.

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are derece guaranteed to be thread safe.

If you do this then there's nothing stopping your callers casting the IEnumerable back to ICollection and then modifying it. ReadOnlyCollection removes this possibility, although it's still possible to access the underlying writable collection via reflection.

Descendants(IEnumerable) Returns a collection of elements that contains the descendant elements of every element and C# ReadOnlyCollectionBase Nedir document in the source collection.

Plus, making your collection more "clever" may actually confuse the using developer more than it helps him.

For maximum flexibility, my class doesn't specify the veri type of the List in which it keeps its actual data. 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 C# ReadOnlyCollectionBase Nasıl Kullanılır List I'm working with, I've forced my class to be instantiated with a data type that the code refers to as 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 C# ReadOnlyCollectionBase Temel Özellikleri IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.

A method like PayUnpaidInvoices being present C# ReadOnlyCollectionBase Temel Özellikleri may lead to second guessings about what "regular" collection methods like Remove and Clear might do. Will it C# ReadOnlyCollectionBase Nerelerde Kullanılıyor just remove invoices from the in-memory collection, or will it delete them from the database?
