Arraylist: Hareketli boyutludur, eleman ekleme/silme anlayışlemleri henüz kolaydır ve farklı bilgi türlerini saklayabilir.
Süflidaki şekilde Kisi isminde oluşturduğumuz derslikı oluşturduğumuz liste nesnesine ekleyelim.
I think that, ideally, the .NET Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's not too hard to create a couple of methods that will allow you to sort an IList kakım you would a List.
All concepts are basically stated in most of the answers above regarding why use interface over concrete implementations.
ToList first? How about returning it? I don't understand what you mean by "method will survive" when using vars? I know it will be a bit more work but won't you just have to change that to the new type bey well? So maybe IList to IList?
The speed difference is sufficiently great that in many cases it may be faster to copy a list to an array, sort the array, and copy the list back, than to try to have a sort routine process the list in place.
class Kisi string ad; string soyad; public string Ad get return ad; grup ad = value; public string Soyad get return soyad; kaş soyad = value;
Then when you need "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and if you need more then extend...
For example, let's say you have a C# IList Neden Kullanmalıyız Person class and a Group class. A Group instance saf many people, so a List here would make sense. When I declare the list object in Group I will use an IList and instantiate it as a List.

I know that IList is the interface and List is the C# IList Nerelerde Kullanılıyor concrete type but I still don't know when to use each one. What I'm doing now is if I don't need the Sort or FindAll methods I use the interface. Am I right? Is there a C# IList Nasıl Kullanılır better way to decide when to use the interface or the concrete type?

You cannot sort an IList in-place through the interface except by using ArrayList.Adapter method in my knowledge.
I have two ILists of the same type returned by NHibernate and have emerged the two IList into one, hence the need for sorting.
ahead of time. Data-binding is a classic example here; a DataSource property usually checks for IList (and IListSource, typically) and then looks at the objects to see what properties are available. It sevimli't use generics in this case.
