Detaylar, Kurgu ve C# ReadOnlyCollectionBase Temel Özellikleri

Wiki Article

I do not pass around Listss if I kişi possibly help it. Generally I have something else that is managing the collection in question, which exposes the collection, for example:

Simply put, Microsoft defined a ReadOnlyCollectionBase, yet did derece use it bey the base class for ReadOnlyCollection when it clearly sounds that this should have been the way.

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

Güç you arrange 25 whole numbers (not necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd?

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

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

4) If you suddenly realise that your collection of choice is inefficient, you sevimli change the underlying collection type without having to go and change all the places where it got passed birli a parameter (can you imagine the trouble you might have with, say, List?)

; but this question convinced me to go ahead and announce an open source project I've had in the works for a while (still a work in progress, but there's some useful stuff in there), which includes an IArray interface (and implementations, naturally) that I think captures exactly what you want here: an indexed, read-only, even covariant

Note that the IReadOnlyList interface works similarly to List and in C# ReadOnlyCollectionBase Nerelerde Kullanılıyor fact güç be used in place of List when you want the elements of the list to be read-only. We will illustrate this with an example in the next section.

When call the above code. The changes happening in the call ---1 is getting C# ReadOnlyCollectionBase Nasıl Kullanılır reflected the CategoryList and its affecting the call 2 . How sevimli I make the CategoryList as ready Only and I am not supposed to change the collection inside the categoryList .But the collection is getting affected .

One possibility is to implement your own thread-safe variant of the ReadOnlyCollection to allow locked access, though this will be non-trivial and non-performant C# ReadOnlyCollectionBase Nerelerde Kullanılıyor if you want to support IEnumerable, and it still

In the “Configure your new project” window shown C# ReadOnlyCollectionBase Kullanımı next, specify the name and location for the new project.

The IEnumerable interface is yet another interface C# ReadOnlyCollectionBase Kullanımı used often to represent read-only collections of veri. If you simply want to enumerate the elements of a collection, you yaşama use IEnumerable birli shown below.
