"Are there any simple groups that appear birli zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?

IList is an interface so you gönül inherit another class and still implement IList while inheriting List prevents you to do so.

Koleksiyonlar, verileri mukannen bir düzende depolamak ve yönetmek yürekin kullanılan data gestaltlarıdır. CollectionBase ile kendi koleksiyonlarınızı oluştururken, bu data gestaltlarını henüz etkili ve mahsuldar bir şekilde kullanabilirsiniz.

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.

In some code this yaşama be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to C# IList Kullanımı call this grup of methods, no other contract implied."

Object gönül 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.

Then when you need C# IList Nasıl Kullanılır "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and C# IList Nasıl Kullanılır if you need more then extend...

In VS2008, when I click on the service reference and C# IList Nerelerde Kullanılıyor select "Configure Service Reference", there is an option to choose how the client de-serializes lists C# IList Nedir returned from the service.

The Cast function is just a reimplementation of the extension method that comes with 3.5 written bey a uygun static method. It is quite ugly and verbose unfortunately.

Aşağıdaki şekilde Kisi adında oluşturduğumuz sınıfı oluşturduğumuz liste nesnesine ekleyelim.

Benefit of using an Interface is that you get to implement your functionality or better yet, the only functionality you require. So, if iteration/enumeration is required only, then there is no need for the Sort, Add methods.

If you use the concrete type all callers need to be updated. If exposed birli IList the caller doesn't have to be changed.

would I run into problems with this? Since could they not pass in an array(that has a fixed size)? Would it be better maybe for a concrete List?
