Don't return a collection directly. Make an accurately named business logic class that reflects the purpose of the collection.

IEnumerable saf been used to represent a read-only collection of veri since the earliest versions of .Kupkuru. The read-only collection interfaces available in .Kemiksiz Core and .NET 5 enable you to design classes that prevent the collections from being modified.

That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase

Note that I split the interface into IReadOnlyMyItem and IWritableMyItem but you don't actually need IWritableMyItem - you could just omit that interface and write:

Well, there is a way. It ain't pretty birli it adds extra stuff on your domain manken, but I just checked and it works.

Distinct(IEnumerable) Returns distinct elements from a sequence by using the default equality comparer to compare values.

If you're tolerant of some "noise" in your own encapsulated code then I would suggest wrapping a T[] array and exposing an IList which happens to be a ReadOnlyCollection:

Average(IEnumerable, Func) Computes the average of a sequence of nullable Int32 values that are obtained by invoking a transform function on each element of the input sequence.

C# Queue dershaneı kullanımı az çok basittir ve çeşitli adımları ciğererir. Bu adımları gerçek bir şekilde izlem ederek, Queue C# ReadOnlyCollectionBase Nedir derslikını cömert bir şekilde kullanabilirsiniz. İşte temel adımlar ve detayları:

Sometimes you may want to use an interface, perhaps because you want to mock the collection during unit testing. Please see my blog entry for adding your own interface to ReadonlyCollection by using an adapter.

Implementers are encouraged to extend this base class instead of creating their own. C# ReadOnlyCollectionBase Nedir Members of this base class are protected and are intended to be used through a derived class only.

Inheriting from a non-generic base class would be ineffecient. If the type was using a C# ReadOnlyCollectionBase Nerelerde Kullanılıyor non-generic base, all it would be would be a thin layer above the base collection, where C# ReadOnlyCollectionBase Kullanımı the generic features would simply derive from casting from the underlying object instances of the base C# ReadOnlyCollectionBase Nerelerde Kullanılıyor collection.

Average(IEnumerable, Func) Computes the average of a sequence of nullable Single values that are obtained by invoking a transform function on each element of the input sequence.

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 bey shown in the code snippet given below.
