Else use List. You hayat't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List hamiş an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

Same principle birli before, reversed. Offer the bare minimum that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

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

Kemiksiz 4.6 (and it will likely be caught by the compiler). But there emanet be more insidious cases, such kakım passing a C# array birli a IList. I am not sure everyone is aware arrays implement IList, which means support for Add should hamiş be assumed.

In some code this kişi be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I C# IList Nasıl Kullanılır just need to call this takım of methods, no other contract implied."

The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it has to use List.

In collections of contiguous elements, such kakım lists, the elements that C# IList Kullanımı follow the insertion point move down to accommodate the new element.

So I have been playing around with some of my methods on how to do this. I am still hamiş sure about the return type(if I C# IList Nedir should make it more concrete or an interface).
