IStructuralComparable arayüzü, çoğu kez Array ve Tuple üzere data konstrüksiyonları tarafından uygulanır. Bu done mimariları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak zıtlaştırma yapar.

The main advantage of this comes in the fact that you güç't add code to collections so whenever you have a native "collection" in your object paradigma, you ALWAYS have non-OO support code spread throughout your project to access it.

For this collection to be useful, however, you need to be able to load that internal list with your collection. The easiest way to do that is to add a constructor to the class that accepts the List to be put in the class' UnderlyingList collection (again, I'm accepting anything that implements the IList interface with the data type specified by T): Public Sub New(InitialList Bey IList(Of T)) UnderlyingList = InitialList

Use ObservableCollection/ListViewCollection and make your own custom ReadOnlyObservableCollection wrapper like in #1 that doesn't implement Add or modifying properties and methods.

DO use the least-specialized type possible as C# ReadOnlyCollectionBase Nedir a parameter type. Most members taking collections as parameters use the IEnumerable interface.

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

For maximum flexibility, my class doesn't specify C# ReadOnlyCollectionBase Nasıl Kullanılır the C# ReadOnlyCollectionBase Temel Özellikleri data 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 class to be instantiated with a data type that the code refers to birli 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 of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.
