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

Then the person calling the method is free to call it with any data type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.

Edit: You do need to be quick to get answers in here. Bey I presented a slightly different syntax to the other answers, I will leave my answer - however, the other answers presented are equally valid.

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.

Convert your IList into List or some other generic collection and then you birey easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

The idea is that you hide the implementation details from the user, and instead provide C# IList Nasıl Kullanılır them with a stable interface. This is to reduce dependency on details that might change in the future.

If you code your own class implementing the IList interface, make sure you also implement C# IList Kullanımı the non-generic IList interface, or the code will yapan with a class cast exception.

I know that IList is the interface and List is C# IList Nerelerde Kullanılıyor the 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 better way to decide when to use the interface or the concrete type?

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked birli helpful. However, I would add that for most developers, most of the time, the tiny difference in yetişek size and performance is not worth worrying about: if in doubt, just C# IList Nerelerde Kullanılıyor use a List.

for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.

Bu şekilde, Dog derslikı IAnimal interface’inin sözleşmesine uymuş olur. Aynı şekilde, farklı efsanevi sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, aşağıdaki kodda bir Cat derslikı tanılamamladım ve IAnimal interface’ini uyguladım.
