Arraylist: Devim bilimi boyutludur, eleman ekleme/silme alışverişlemleri elan kolaydır ve farklı data türlerini saklayabilir.

Same principle birli before, reversed. Offer the bare minimum that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does derece contain an array, so all of a sudden, we had almost no use of the large object heap.

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

Safi 4.6 (and it will likely be caught by the compiler). But there can be more insidious cases, such bey passing a C# array birli a IList. I am derece sure everyone is aware arrays implement IList, which means support for Add should hamiş be assumed.

so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

The cost to do this is minimal, why derece save yourself the headache later? It's what the interface principle is all about.

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed kakım well. This is because a class adhering C# IList Kullanımı to IList guarantees a certain behavior that is hamiş guaranteed by a concrete type using List. Also having the power to do something like modify the default implementation of List on a class Implementing IList for say the .Add, .Remove or any other IList method gives the developer a lot

For C# IList Nerelerde Kullanılıyor collections you should aim to use IEnumerable where possible. This gives the most flexibility but is derece always suited.

It is like this other question. The other question shares C# IList Nedir a lot of common ground, but is arguably not a true duplicate. In either case though, this is hamiş opinion-based. What C# IList Nasıl Kullanılır may have happened is that the closer might have just looked at this question's title, without reading the C# IList Neden Kullanmalıyız question itself. The body is objective.

In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they hayat't add or remove items from your object, they kişi only act against the objects. If you need to expose a collection outside of a class, but don't want to let the caller change the collection, this is one way of doing it. On the other hand, if you are returning an empty collection that you expect/want them to populate, then an IEnumerable is unsuitable.
