But yeah, I would have to agree that there's definitely a "hole" in the BCL where a read-only indexed collection interface should go. IList is just too multi-purpose.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

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

Descendants(IEnumerable, XName) Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

I currently have return data; wrapped by a ReaderWriterLockSlim to protect the collection from sharing violations.

For this collection to be useful, however, you need to be able to load that internal list with your collection. The easiest way to do that is to add a constructor to the class that accepts the List to be put in the class' UnderlyingList collection (again, I'm accepting anything that implements the IList interface with the veri type specified by T): Public Sub New(InitialList Bey IList(Of T)) UnderlyingList = InitialList

Istifham 1: C# Metot nedir? C# Metot, makul bir meselelevi adına getiren kod bloklarını muhtevaermiş konstrüksiyonlardır. C# ReadOnlyCollectionBase Nedir Metotlar, kodun yeni baştan kullanılabilirliğini pozitifrır ve kod muhtelitşıklığını azaltır.

Sonuç C# ReadOnlyCollectionBase Kullanımı olarak System.Collections ad düzlükı altında karşımıza 7 pare non-generic ve 7 adette generic dershane çıkmaktadır. Hamur önemli olan C# ReadOnlyCollectionBase Nerelerde Kullanılıyor hak sınıfı dosdoğru yerde kullanmaktır.

This article discusses these read-only immutable collection types in .NET Core and how you kişi work with them in C#.

A ReadOnlyCollectionBase instance is always read-only. See CollectionBase for a modifiable version of this class.

ElementAtOrDefault(IEnumerable, Int32) Returns the element at a specified index in a sequence or a default value if the index is out of range.

Here’s where you birey take advantage of IReadOnlyList to ensure that the returned data cannot be changed. By changing the return type of the GetAuthors method from List to IReadOnlyList we can make our collection read-only.

For maximum flexibility, my class doesn't specify the data type of the List in which it keeps its actual data. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather C# ReadOnlyCollectionBase Nasıl Kullanılır 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 as T. Wherever in my code I need to specify my List's veri type, I just 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. Listing 1. The basics of the PhvReadOnlyList class.

(There are plenty of other options for C# ReadOnlyCollectionBase Nerelerde Kullanılıyor wrapping trivially - the birçok thing about Skip over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
