C# IList Nerelerde Kullanılıyor Için 5-İkinci Trick

"Are there any simple groups that appear bey 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 belli başlı bir düzende depolamak ve yönetmek kucakin kullanılan bilgi gestaltlarıdır. CollectionBase ile kendi koleksiyonlarınızı oluştururken, bu veri yapılarını elan dinamik ve randımanlı bir şekilde kullanabilirsiniz.

Sıfır alt uçına ehil uslu boyutlu diziler otomatik olarak uygular IList. Bu, diziler ve diğer derlem türleri arasında yineleme uygulamak sinein aynı kodu kullanabilen genel yöntemler oluşturmanıza imkân tanır.

Basically, I need to see some actual code examples of how using IList would have solved some problem over just taking List into everything.

so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

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, birli shown above.

From my reading I think I could have used IEnumberable instead of IList since I am just looping through stuff.

Whether C# IList Nerelerde Kullanılıyor you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created -- this C# IList Neden Kullanmalıyız is an API design decision, and there's no hard and fast rule. You have to weigh their ability to make full use of the object against their ability to easily use a portion of the objects C# IList Nerelerde Kullanılıyor functionality (and of course whether you WANT them to be making full use of the object).

On the other hand, when returning an object out of a function, you want to give the user the richest possible set of operations without them having to cast around. So in that case, if it's a List internally, return a copy kakım a List.

If you're just enumerating over the values, you should be using IEnumerable. Every type of datatype that birey hold more than one C# IList Neden Kullanmalıyız value implements IEnumerable (or should) and makes your method hugely flexible.

The other general reason for using interfaces is to expose the asgari amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a veri object that implements IList.
