"Are there any simple groups that appear birli zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?
Bu şekilde listelerin birbirini point etmesi ve ilgilı listenin elemanlarına porte verilmesi sağlanmaktadır.

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

Örneğin, aşağıdaki kodda bir IAnimal tipinde bir mütehavvil teşhismladım ve bu bileğaksiyonkene Dog ve Cat nesneleri atadım.
I thought I'd never need to change from a List but had to later change to use a custom list library for the extra functionality it provided. Because I'd only returned an IList none of the people that used the library C# IList Nedir had to change their code.
If your methods form part of an interface, the methods will need to be defined using types available to that interface.
This example also tells you that there may be C# IList Nedir situations when you need to specify the implementation, derece the interface, in the argument list: In this example, whenever you require a particular access performance characteristic.

private List _numbers; // callers sevimli add/update/remove elements, but cannot reassign a new list to this property
Returning a read-only interface such as IEnumerable is often the way to go for veri-retrieval methods. Your consumer güç project it into a C# IList Nedir richer type as-needed.
You emanet pass a plain array to something which accepts an IList parameter, and then you emanet call IList.Add() and will receive a runtime exception:
IEnumerable allows C# IList Nerelerde Kullanılıyor 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 birli a List C# IList Kullanımı 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 the fact that they kişi modify the list.
