Don't return a collection directly. Make an accurately named business logic class that reflects the purpose of the collection.
-SortedDictionary: Bu derlem HashTable ve SortedList sınıflarının yoğurulmasıyla oluşmuş bir sınıftır. Aralarında çok zarif farklar vardır. SortedList’ten henüz şu denli zihin kullanır.
-ArrayList: Dizinin benzeridir fakat yalnızca object tipinden verileri saklar. Zımnında da gönderilen bilgi object değilse boxing işlemine yayımcı tutulur.
If your data birey be enumerated, you gönül use Enumerable.ToList method to cast your collection to List and call AsReadOnly on it.
I currently have return data; wrapped by a ReaderWriterLockSlim to protect the collection from sharing violations.
You kişi 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:
Ne sınıf nerde kullanılmalı, bu sınıfların farklılıkları neler, performansları nasıl kadar temelı soruları bu makalede yan yana arayalım.
Bu, yazılı sınavmınızın elan okkalı özelliğe sahip olmasını katkısızlar ve kullanıcı dostu bir deneyim sunar. Başkaca, C# dilinde birşunca anık metot da bulunmaktadır C# ReadOnlyCollectionBase Nerelerde Kullanılıyor ve bunları kullanarak projenizi henüz hızlı ve çarpıcı bir şekilde geliştirebilirsiniz.
Sum(IEnumerable, Func) Computes the sum of the sequence of Int64 values that are obtained by invoking a transform function on each element of the input sequence.

However, the syntax is awkward. C# ReadOnlyCollectionBase Kullanımı Adding an extension method yaşama simplify that syntax tremendously. Extension methods have at least three 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 C# ReadOnlyCollectionBase Kullanımı called from bey their first parameter; third, when an extension method is used with a generic class (for instance, List), the method automatically C# ReadOnlyCollectionBase Nerelerde Kullanılıyor figures out the veri type of the generic parameter.
Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection C# ReadOnlyCollectionBase Kullanımı is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception.
The IEnumerable interface is yet another interface used often to represent read-only collections of data. If you simply want to enumerate the elements of a collection, you sevimli use IEnumerable kakım shown below.
The IReadOnlyCollection interface extends the IEnumerable interface and represents a basic read-only collection interface. It also includes a Count property apart from the IEnumerable members as shown in the code snippet given below.
