5 Basit Teknikleri için C# IList Nedir

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 as a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

Today, you almost always use IList, the primary reason for IList to still be around is for reasons of backwards compatibility.

Edit: You do need to be quick to get answers in here. Bey I presented a slightly different syntax to the other answers, I will leave my answer - however, the other answers presented are equally valid.

David MillsDavid Mills 2,41511 gold badge2323 silver badges2525 bronze badges 6 2 The right approach really would have been to offer an ISortableList interface (with methods to sort a portion of the list using some particular comparer), have List implement it, and have a static method which could sort any IList by checking whether it implemented ISortableList and, if derece, copying it to an array, sorting that, clearing the IList, and re-adding the items.

I tend to follow Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.

You may not ever need that option, but it's an argument. I think C# IList Kullanımı it's the entire argument for returning the interface instead of the concrete type. It's worth mentioning, but in this case it has a serious flaw.

If your methods form part of an interface, the methods will need to be defined using types available to that interface.

In most C# IList Kullanımı 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 C# IList Nedir fit if you don't need to add items. If you need to add to the collection, use the concrete type, List.

class Kisi string ad; string soyad; public string Ad get return ad; seki ad = value; public string Soyad get return soyad; kaş soyad = value;

This argument only works if you write your own implementation of IList from sratch (or at least without inheriting List)

Benefit of using an Interface is that you get to implement your functionality or better yet, the only functionality you require. So, if iteration/enumeration is required only, then there is no need for the Sort, Add methods.

You accept an Interface bey a parameter for a method because that allows the caller to submit different concrete types kakım arguments. Given your example method LogAllChecked, the parameter someClasses could be of various types, and C# IList Nerelerde Kullanılıyor for the person writing

Encapsulation relies on telling clients birli little about the implementation of your class birli possible. If you return a concrete List, you gönül't then change to some other better type without forcing all of your clients to re-compile/update.
