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.

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 hamiş contain an array, so all of a sudden, we had almost no use of the large object heap.

If you think that interfaces are useful only for building over-sized, grandiose architectures and have no place in small shops, then I hope that the person sitting across from you in the interview isn't me.

In this specific case since you're essentially talking about a language construct, derece a custom one it generally won't matter, but say for example that you found List didn't support something you needed.

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you yaşama't justify it, use the interface.

Object dirilik C# IList Neden Kullanmalıyız be a T too. Doing this will save you headache if you decide to use a Stack or some other data structure further down the road. If all you need to do in the function is foreach through it, IEnumerable is really all you should be asking for.

If you aren't sure, or are afraid that if you change it in future you'll be breaking other people's code, then go more general.

Sevimli you please provide me some link to a class that implements IList interface or provide me a code that at least implements Add and Remove methods?

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked kakım helpful. However, I would add that for most developers, most of the time, the tiny difference in izlence size and performance is hamiş worth worrying about: if in doubt, just use a List.

I have two ILists of the same type returned by NHibernate and C# IList Nedir have emerged the two IList into one, hence the need for sorting.

Fakat list kullanımında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye teşhismlayabiliriz ancak kullanılacak veriler makine plakası,telefon numarası kabil skorsı yeni veriler kullanıcak ise behemehâl list olarak saklanmalıdır.Şimdi C#’ta list kullanımı için örneğimize bakalım.
