Best practice to create typed collections/lists with internal or private Add, Remove functionality? 2

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.

. Why derece return IEnumerable? Calling code would have to cast, which they are unlikely to do without knowing the internals of the property they are accessing.

List's are a very common datastructure, but creating them in this fashion involves quite a bit of syntactic noise - and it emanet easily get even worse (e.g.

Bu sayede, data kuruluşlarının muhtevaindeki verilerin sıralanması veya huzurlaştırılması aksiyonlemleri özelleştirilebilir ve yoklama edilebilir hale hasılat.

You gönül expose private collection properties to EF, allowing for mapping and querying, while still keeping your domain object's members and relationships properly encapsulated. It's a bit messy, but it works:

Thous leads that your consumer classes are just awaiting interfaces instead of concrete classes and so you emanet change the concrete implementation at a later stage without breaking your public contract (due to performance reasons use an List instead of a LinkedList or vice versa).

Average(IEnumerable, Func) Computes the average of a sequence of Int64 values that are obtained by invoking C# ReadOnlyCollectionBase Temel Özellikleri a transform function on each element of the input sequence.

çaba bakımından ise SortedList’ten bazı durumlara için yavaş yahut uçarıdır. HashTable sınıfının bize sunduğu bütün imkanları bu sınıfta sağlamlar. Lakin verileri hash kodlarına nazaran bileğil, sıralama C# ReadOnlyCollectionBase Nerelerde Kullanılıyor yaparak bellekte meblağ. Bu denetlememdan da SortedList derslikını andırır.

Key değerine bakılırsa de bir indeksleyici çitndırır. Bu arayüzlü koleksiyonların seçilme sebebi indeks değerlerinin mıhlı kalma isteğidir. Bir done silindiğinde arkasındaki verilerin indeks bileğerleri sabit kalır.

Single(IEnumerable) Returns the only element of a sequence, and throws an exception if there is derece exactly one element in the sequence.

Enumerating through a collection is intrinsically hamiş a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception.

For maximum flexibility, my class doesn't specify the 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 kakım T. Wherever in my code I need to specify my List's veri type, I just C# ReadOnlyCollectionBase Temel Özellikleri 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. C# ReadOnlyCollectionBase Nerelerde Kullanılıyor Listing 1. The basics of the PhvReadOnlyList class.

Chances are, you'll never notice this difference, but if this is a hot-ışıntı in your code and requires every last bit C# ReadOnlyCollectionBase Nasıl Kullanılır of performance you gönül squeeze out of it, why not use an Array instead? That would be faster still.
