To guarantee thread safety during enumeration, you güç either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.
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.
foreach C# dilinin deyimi (for eachVisual Basic'te) numaralandırıcıların muhtelitşıklığını gizler. Bu nedenle, numaralandırıcıyı vasıtasız resmetmek yerine kullanılması foreach önerilir.
Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Single values that are obtained by invoking a transform function on each element of the input sequence.
The main advantage of this comes in the fact that you hayat't add code to collections so whenever you have a native "collection" in your object paradigma, you ALWAYS have non-OO support code spread throughout your project to access it.
Distinct(IEnumerable) Returns distinct elements from a sequence by using the default equality comparer to compare values.
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).
ElementAtOrDefault(IEnumerable, Index) Returns the element at a specified index in a sequence or a default value if the index is out of range.
Ivinti C# ReadOnlyCollectionBase Kullanımı itibarıyla ise SortedList’ten bazı durumlara için yavaş yahut aculdır. HashTable klasının bize sunduğu bütün imkanları bu sınıfta sağlar. Ama verileri hash kodlarına bakılırsa bileğil, C# ReadOnlyCollectionBase Nedir sıralama yaparak bellekte tutar. Bu falmdan da SortedList sınıfını andırır.
Sometimes you may want to C# ReadOnlyCollectionBase Nasıl Kullanılır use an interface, perhaps because you want to mock the collection during unit testing. Please see my C# ReadOnlyCollectionBase Temel Özellikleri blog entry for adding your own interface to ReadonlyCollection by using an adapter.
Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are derece guaranteed to be thread safe.

End Sub And that's all you need to write. The class that's using your new read-only collection would be identical to the class that used my custom PhvReadOnlyList. In fact, if that's all you want, then you don't even need to create your own version of the ReadOnlyCollectionBase class -- the .
One should note that C# ReadOnlyCollectionBase Nerelerde Kullanılıyor aku's answer will only protect the list birli being read only. Elements in the list are still very writable.
