I know there özgü been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.
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.

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.
Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does not.

Dizilerde olduğu C# IList Nedir gibi ilkin kaç adet elemanla çkızılışılacağı belirtilmek zorunda değildir. Dizilerde evetğu kabil eleman ekleme, C# IList Nerelerde Kullanılıyor silme davranışlemleri uygulanabilir ve araya eleman eklenebilir. Ilgilı listeler esenladığı avantajlardan dolayı henüz çok tercih edilir.
If your methods form part of an interface, the methods will need to be defined using types available to that interface.
And, if you don't even need everything in IList you güç always use IEnumerable too. With çağcıl compilers and processors, I don't think there is really any speed difference, so this is more just a matter of style.

Then I looked in my view(mvc) and found that I actually needed the count method kakım I needed 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.
When talking about return types, the more C# IList Neden Kullanmalıyız specific you are, the more flexible callers kişi be with it.
ahead of time. Data-binding is a classic example here; a DataSource property usually checks for IList (and IListSource, C# IList Nedir typically) C# IList Nerelerde Kullanılıyor and then looks at the objects to see what properties are available. It dirilik't use generics in this case.
