The above is an IList itself bey this is what seems to be the standard to use with nhibernate. Otherwise I might have returned IEnumberable back but derece sure. Still, I kişi't figure out what the user would 100% need(that's where returning a concrete has an advantage over).

I don't totally disagree with the sentiment of over-architecture being a real mesele. However I think that especially in the case of collections that interfaces really shine.

Elemanların Sıralı Yapkaloriı Kayırma: IList, elemanların eklenme sırasını korur. Bu özellik, veri yapısının sıralı olmasını ve programın beklentilerine münasip çkızılışmasını sağlamlar.

Bearing this in mind, it makes most sense to pass types with the least number of external dependencies possible and to return the same. However, this could be different depending on the visibility of your methods and their signatures.

Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does not.

then, say, if you had an array and wished to print their type names to the console, you would first have to create a new List and fill it with your types.

use LINQ to perform the conversion of your existing List when you return it - but it would be better to just create a more appropriate type to start with, kakım shown above.

If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does derece apply to collections where elements are conceptually grouped into buckets, such bey a hash table.

If you started with a concrete type and you decided to change to another one, even if it uses C# IList Nedir the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type. Share Improve this answer Follow

By asking for more than you need, you (1) make the caller do C# IList Nerelerde Kullanılıyor unnecessary work to satisfy your unnecessary demands, and (2) communicate falsehoods to the reader. Ask only for C# IList Nedir what you're going to use. That way if the caller has a sequence, they don't need to call ToList on it to satisfy your demand.

Is IList a good fit for your organisation? If a colleague asks you C# IList Nedir to change a method signature to use IList instead of List, ask them how they'd add an element to an IList. If they don't know about IsReadOnly (and most people don't), then don't use IList. Ever.

If you use a concrete implementation of list, another implementation of the same list will not be supported C# IList Nasıl Kullanılır by your code.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they gönül't add or remove items from your object, they güç 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.
