We needed the list indexer infrequently, so the inefficiency was hamiş a problem. If it had been, we could have provided some other implementation of IList, perhaps bey a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.
C# List ciğerindeki verileri yazdırmak ciğerin dundaki dü döngüden biri kullanılarak değerleri ekrana yazdırma işlemlemi dokumalabilir.
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 as a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

Convert your IList into List or some other generic collection and then you can easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)
Object birey be a T too. Doing this will C# IList Nasıl Kullanılır 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.
Then when you need "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and if you need more then extend...
The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.
Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.
Of course that only need C# IList Nedir apply to methods that are externally visible (i.e. public methods). I personally use interfaces even in internal code, but bey you are able to change all the code yourself if you make breaking changes it's not strictly necessary.
List communicates "I need to get and grup the elements of C# IList Nasıl Kullanılır this sequence in arbitrary order and I only accept lists; I do derece accept arrays."
In C# IList Nasıl Kullanılır particular, IList lets you use the indexer, and add/remove items; things that IEnumerable don't let you do.
This works, because only the outer list is created C# IList Nerelerde Kullanılıyor in the first place. You birey then insert individual items that are compatible with IList:
