To guarantee thread safety during enumeration, you hayat either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.

In EF Core, you birey encapsulate collections and achieve true domain modeling by using backing fields.

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

Imagine we have existing örnek with Organization => Employees already kaş up. To apply this technique, we need to change Organization biçim a bit:

Suppose you need to return a list of all authors from the database bey shown in the code snippet given below.

public IEnumerable Employees => EmployeesInternal.Skip(0); // this is property accessor that will be used to define prototip and/or in `Include` statements, could be marked kakım internal if your domain/persistance/services are in the same assembly

HashTable hash kodlarına bakılırsa dizdiğinden muayyen bir sıralaması yoktur.Algoritması bu kodların ortamında gizlidr. Dictionary ise verilerin ekleniş sırasını hiç bileğkârtirmeden saklamıştır.

well, NHibernate kişi grup private class fields and this means that you dirilik expose it using a public property encapsulating the field as read-only collection.

Elements(IEnumerable, XName) Returns a filtered collection of the child elements of every element and document in the source collection. Only elements that have a matching XName C# ReadOnlyCollectionBase Kullanımı are included in the collection.

However, the syntax is awkward. Adding an extension method birey 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 called from bey their first parameter; third, when an extension method is used with a generic class (for instance, List), the C# ReadOnlyCollectionBase Nedir method automatically figures out the veri type of the generic parameter.

Enumerating through a collection is intrinsically not a thread-safe procedure. Even when C# ReadOnlyCollectionBase Nedir a collection is synchronized, other threads sevimli still modify the collection, which causes the enumerator to throw an exception.

You emanet loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also C# ReadOnlyCollectionBase Temel Özellikleri possible with the Count property and indexer. CopyTo provides a way to copy the elements C# ReadOnlyCollectionBase Nasıl Kullanılır to an array. You must allocate the array yourself.
