Else use List. You emanet'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"
Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.
Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, hamiş add or remove. Accepting an interface birli a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."
Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:

IList on the other hand is an Interface. Basically, if you want to create your own custom List, say a list class called BookList, then you sevimli use the Interface C# IList Nasıl Kullanılır to give you basic methods and structure to your new class. IList is for when you want to create your own, special sub-class that implements List.

Now I am returning IList for the simple fact that I will then add this to my domain biçim what saf C# IList Neden Kullanmalıyız a property like this:
For collections you should aim to use IEnumerable where possible. This gives the most flexibility but is derece always suited.
You would because defining an IList or an ICollection would open up for other implementations of your interfaces.

Then I looked in my view(mvc) and found that I actually needed the count method kakım I needed C# IList Nasıl Kullanılır to use a for loop. So in my own application I under estimated what I actually needed how do you anticipate what someone else will need or not need.
In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element.
There is a complication though that dynamic hayat't see explicit implementations, so something kişi implement IList and IList-of-T and yet still be completely unusable from dynamic.
