Arraylist: Canlı boyutludur, eleman ekleme/silme teamüllemleri henüz kolaydır ve farklı muta türlerini saklayabilir.

Same principle birli 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.

Interface’ler karşı daha ziyade vukuf olmak isterseniz, dundaki kaynaklara çekmece atabilirsiniz:

For instance I was switching one of my return types to a IList then I well I am probably just going to enumerate over them anyways lets just return an IEnumberable.

Use whatever you want. It's your method. You're the only one who gets to see the internal implementation details of the method.

You emanet have an instance of an interface, but you need to initialize it with a class that implements that interface such birli:

Remove Silinmesini istenilen değeri siler. Silinecek paha liste içre ansızın bir araba olması durumunda ilk kıymeti kaldırır. Bu metodu ekseri referans tipler ile bedel çıkarmak midein kullanılır. Ama valör tipleri ile C# IList Neden Kullanmalıyız de kullanılabilir.

If you specify your methods to return an interface that means you are free to change the exact implementation later on without the consuming method ever knowing.

In most cases, if you are using a List and you think you could use a narrower interface instead - why hamiş IEnumerable? This is often a better fit if you don't need to add items. If you need to add to the collection, use the C# IList Kullanımı concrete C# IList Nasıl Kullanılır type, List.

Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.

If you're working within a single method (or even in a single class or assembly in some cases) and no one C# IList Nerelerde Kullanılıyor outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you C# IList Nedir only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

Returning a read-only interface such birli IEnumerable is often the way to go for data-retrieval methods. Your consumer sevimli project it into a richer type bey-needed.

In particular, IList lets you use the indexer, and add/remove items; things that IEnumerable don't let you do.

It doesn't affect the signature of the method, and is grup in stone at compile time. You should instead be helping him get over his confusion about declaring his local like IList foo = new List - this is where his confusion clearly lies.
