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 not 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 as 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.

You pass the interface so that no matter what concrete implementation of that interface you use, your code will support it.

So when writing a function or method that takes a collection, write it hamiş to take a List, but an IList, an ICollection, or IEnumerable. The generic interfaces will still work even for heterogenous lists because System.

The accepted answer by @DavidMills is quite good, but I think it güç be improved upon. For one, there is no need to define the ComparisonComparer class when the framework already includes a static method Comparer.Create(Comparison). This method yaşama be used to create an IComparison on the fly.

The speed difference is sufficiently great that in many cases it may be faster to copy a list to an array, sort the array, and copy the list back, than to try to have a sort routine process the list in place.

Object güç 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.

Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback C# IList Neden Kullanmalıyız system. For more information see: .

Hayat you please provide me some link to a class that implements IList interface or provide me a code that at least implements Add and Remove methods?

Then I looked in my view(mvc) and found that I actually needed the count method bey I needed to use a C# IList Kullanımı for loop. So in my own application I under estimated what I actually needed how do you anticipate what someone else will need or hamiş need.

Unless you have a very compelling reason to do so, your best bet will be to inherit C# IList Neden Kullanmalıyız from System.Collections.ObjectModel.Collection since it saf everything you need.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they birey't add or remove items from your object, they emanet only act against the objects. If you need to expose a collection outside of a class, but don't want to C# IList Neden Kullanmalıyız let the caller change the collection, this is one way of doing it. On the other hand, if you are returning an empty collection that you expect/want them C# IList Kullanımı to populate, then an IEnumerable is unsuitable.
