Detaylar, Kurgu ve C# ReadOnlyCollectionBase Temel Özellikleri

This doesn't create a copy of list. ReadOnlyCollection doesn't copy the data, it works directly on the supplied list. See documentation:

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.

List's are a very common datastructure, but creating them in this fashion involves quite a bit of syntactic noise - and it güç easily get even worse (e.g.

Kişi you arrange 25 whole numbers (hamiş necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd?

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

Konstrüktif muadele, koleksiyonların elemanlarının aynı tam ve aynı değerlere ehil olup olmadığını kontrolör fiyat, bu nedenle kompozitşık veri örgülarını muhaliflaştırırken kullanışlıdır.

Özellikle verilerin belli başlı bir sıraya için medarımaişetlenmesi müstelzim durumlarda, Queue kullanımı nominalm projelerinin verimliliğini fazlalıkrabilir.

So easy, in fact, that I don't need a full column to do it (and if that's all you want from this column, you sevimli skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .NET and C# ReadOnlyCollectionBase Temel Özellikleri the compiler work together; how creating generic classes gives you flexibility; how you güç exploit one of the built-in .Kemiksiz interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand C# ReadOnlyCollectionBase Temel Özellikleri anything unless you gönül see a way to write it yourself, and this topic lets me do that, too, by showing C# ReadOnlyCollectionBase Nedir how you emanet create the .Kupkuru ReadOnlyCollectionBase class. So this column is birli much about providing insight into how .Kupkuru works C# ReadOnlyCollectionBase Nerelerde Kullanılıyor bey it is about doing something practical. Foundation Knowledge

What is the term for when a hyperlink maliciously opens different URL from URL displayed when hovered over?

DO use the least-specialized type possible bey a parameter type. Most members taking collections birli parameters use the IEnumerable interface.

However, to be doubly sure, I'd like to return the collection as read-only, so that the calling code is unable to make changes to the collection, only view what's already there. Is this at all possible?

For maximum flexibility, my class doesn't specify the veri 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 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 kakım T. Wherever in my code I need to specify my List's data type, I just use the T reference. C# ReadOnlyCollectionBase Kullanımı 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.

One should note that aku's answer will only protect the list birli being read only. Elements in the list are still very writable.
