I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method birli well kakım casting to a List but none of these seemed overly elegant.

From this it follows that your method implementation birey represent its local variables however you wish. The implementation details are not exposed. Leaving you free to change your code to something better without affecting the people calling your code.

Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return veri.

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, hamiş a custom one it generally won't matter, but say for example that you found List didn't support something you needed.

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.

Object birey 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.

But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

Veri Depolama: Uygulamalarda bulaşan verileri veya işleme esnasında oluşan verileri depolamak için kullanılabilir.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they kişi't add or remove items from your object, they emanet only act against the objects.
