I don't totally disagree with the sentiment of over-architecture being a real problem. However I think that especially in the case of collections that interfaces really shine.
Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, hamiş add or remove. Accepting an interface kakım a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."
A List object allows you to create a list, add things to it, remove it, update it, index into it and etc. List is used whenever you just want a generic list where you specify object type in it and that's it.
In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.
so its safety for you and freedom to the coder who is writing concrete implementation C# IList Nedir to change or add C# IList Nerelerde Kullanılıyor more functionality to his concrete class.
Inside the method, you should use var, instead of IList or List. When your data source changes to come from a method instead, your onlySomeInts method will survive.
IList is an Interface, hamiş a class. If you want to initialize it, you need to C# IList Nedir initialize it to a class that implements IList, depending on your specific needs internally. Usually, IList is initialized with a List.
For example, let's say you have a Person class and a Group class. A Group instance başmaklık many C# IList Kullanımı people, so a List here would make sense. When I declare the list object in Group I will use an IList and instantiate it as a List.
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
It is like this other question. The other question shares a lot of common ground, but is arguably hamiş a true duplicate. In either case though, this is derece opinion-based. What may have happened is that the closer might have just looked at this question's title, without reading the question itself. The body is objective.

Dizin aracılığıyla erişilebilen nesnelerin mutlak olarak belirlenmiş bir listesini temaşa fiyat. Listeleri arama, C# IList Neden Kullanmalıyız sıralama ve işleme yöntemleri esenlar.
Encapsulation relies on telling clients bey little about the implementation of your class bey possible. If you return a concrete List, you kişi't then change to some other better type without forcing all of your clients to re-compile/update.
