We needed the list indexer infrequently, so the inefficiency was hamiş a sorun. If it had been, we could have provided some other implementation of IList, perhaps birli a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

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

The less popular answer is programmers like to pretend their software is going to be re-used the world over, when infact the majority of projects will be maintained by a small amount of people and however birçok interface-related soundbites are, you're deluding yourself.

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.

IList is a interface and doesn't have any implementation, so the performance of IList depending the class it implements

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.

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.

Don't you know in advance if your method needs a list that sevimli take additional members; don't you specify that in the method signature? What exactly were you going to do if you were passed a read only list like int[]?

; being aware of the definition of the interface ie. all abstract methods that are there to be implemented by any class inheriting the interface. so if some C# IList Nasıl Kullanılır one makes a huge class of his own with several methods besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case C# IList Nasıl Kullanılır the interface) and assign the concrete class object to it.

class Kisi string ad; string soyad; public string Ad get return ad; takım ad = value; public string Soyad get return soyad; seki C# IList Nedir soyad = value;

It is like this other question. The C# IList Nasıl Kullanılır other question shares a lot of common ground, but is arguably hamiş a true duplicate. In either case though, this is hamiş 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.

Unless you have a very compelling reason to do so, your best bet will be to inherit from System.Collections.ObjectModel.Collection since it has everything you need.

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property as a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on C# IList Neden Kullanmalıyız the fact that they birey modify the list.
