IStructuralComparable arayüzü, genellikle Array ve Tuple kadar bilgi örgüları tarafından uygulanır. Bu veri konstrüksiyonları, elemanlarının sıralamasını ve yapısını dikkate alarak kontralaştırma yapar.

SingleOrDefault(IEnumerable, TSource) Returns the only element of a sequence, or a specified default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence.

I was thinking about creating a new class derived from ReadOnlyCollection (class ReadOnlyMyCollection : ReadOnlyCollection or class ReadOnlyMyCollection : ReadOnlyCollection) which returns the read-only wrapper class (ReadOnlyMyItem) through the square brackets operator, but either the square brackets operator is hamiş marked birli virtual and the return type is not even the same or the constructor doesn't have an IList of the wrapper class (IList) to use. Should I build the class (ReadOnlyMyCollection) from scratch?

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.

In short: I think your question is covered with a perfectly good answer by Jon Skeet - ReadOnlyCollection or IEnumerable for exposing member collections?

However, the syntax is awkward. Adding an extension method emanet simplify that syntax tremendously. Extension methods have at least three C# ReadOnlyCollectionBase Nerelerde Kullanılıyor convenient features: The first is that they attach themselves to whatever classes you specify, automatically appearing in the IntelliSense dropdown lists for those objects; second, they're automatically passed whatever object they're called from kakım their first parameter; third, C# ReadOnlyCollectionBase Nedir when an extension method is used with a generic class (for instance, List), the method automatically figures out the veri type of the generic parameter.

Inheriting from a non-generic base class would be ineffecient. If the type was using a non-generic base, all it 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.
