We needed the list indexer infrequently, so the inefficiency was hamiş a sorun. If it had been, we could have provided some other implementation of IList, perhaps as a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

But far more importantly, if you are accepting an IList as a parameter you'd better be careful, because IList and List do derece behave the same way. Despite the similarity in name, and despite sharing an interface

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, not add or remove. Accepting an interface kakım a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

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.

This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you can be sure that your list is not going to be modified. When you are the person implementing the method and you say you C# IList Nasıl Kullanılır accept an IEnumerable because all you need to do is iterate through that list.

The class name List may be changed in next .safi framework but the interface is never going to change kakım interface is contract.

If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such C# IList Neden Kullanmalıyız kakım a hash table.

If the parameter type is IList, then the caller özgü much more freedom, and dirilik use classes you never heard about, which may not even have existed when your code was written.

List derslikı teşhismlanırken T tip bileğmeselekenini düzenır. Doğrusu listenin içeriğinde hangi türden nesne yada değhizmetkenlerin olacağını belirler.

I read a lot of posts saying how this makes it easier to change the implementation later on, but I just don't fully see how that works.
