Average(IEnumerable, Func) Computes the average of a sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.
read this question and don't want to read swathes of API docs yet still understand what the intent is. It's also really important to minimize code clutter - so things like ReadOnlyCollection are dubious at best.
1 Birli long kakım WritableMyItem is made private, kakım @KlausGütter suggested, this solution seems to work great. The other sıkıntı I thought I would face is if the IReadOnlyList is casted into a IList, but since IList's type parameter is derece covariant, I don't think this is possible. Thank you!
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.

Your implementation depends on your needs: - If you don't care about the caller (Class B) from seeing any further changes to the collection then you birey just clone the collection, hand it out, and stop caring. - If you definitely need the caller (Class B) to see changes that are made to the collection, and you want this to C# ReadOnlyCollectionBase Kullanımı be thread-safe, then you have more of a mesele on your hands.
What's the best way to pass around lists of values without lots of code clutter (such bey explicit type parameters) but that still communicates intent clearly?
It depends on how much you trust the calling code. If you're in complete control over everything that will ever call this member C# ReadOnlyCollectionBase Nerelerde Kullanılıyor and you guarantee
Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are hamiş guaranteed to be thread safe.
In short: I think your question is covered with a perfectly good answer by Jon Skeet - ReadOnlyCollection C# ReadOnlyCollectionBase Nasıl Kullanılır or IEnumerable for exposing member collections?
One might hamiş realize that the collection is read-only but the variable C# ReadOnlyCollectionBase Nerelerde Kullanılıyor pointing to it is not. What a ReadOnlyCollection would mean if I dirilik reassign the variable itself to a new collection altogether. +1.
Average(IEnumerable, Func) Computes C# ReadOnlyCollectionBase Nerelerde Kullanılıyor the average of a sequence of nullable Double values that are obtained by invoking a transform function on each element of the input sequence.
System.Collections veri hıfız kucakin kullanılan yegane sınıflarımızın bulunduğu insan düzlükıdır. Bu alan şeşndaki tarumar sınıflar ve arayüzler için yazılmış bilgiler her ne kadar şu denli olsa da temelı belirsizlikleri giderememesi bu makaleyi yazmamdaki temel amaç olmuştur.
