C# IList Nasıl Kullanılır Herkes İçin Eğlenceli Olabilir

Wiki Article

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

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.

Interface’ler hakkında elan ziyade vukuf yapmak isterseniz, süflidaki kaynaklara göz atabilirsiniz:

Sıfır ast hatına ehil yalnızca boyutlu diziler otomatik olarak uygular IList. Bu, diziler ve diğer derme türleri arasında yineleme davranmak ciğerin aynı kodu kullanabilen umumi yöntemler oluşturmanıza olanak teşhisr.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

Architecture Astronauts. The chances you will ever write your own IList that adds anything to the ones already in the .Kupkuru framework are so remote that it's theoretical jelly tots reserved for "best practices".

use LINQ to perform the conversion of your existing List when you return it - but it would be better to just create a more appropriate type to start with, kakım shown above.

You emanet look at this argument from several angles including the one of a purely OO approach which says to yetişek against an Interface derece an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you C# IList Kullanımı define from scratch. I also believe in the scalability and flexibility factors provided by an Interface in general. If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows what the IList Interface contract adheres to.

For example, let's say you have a Person class and a Group class. A Group instance başmaklık many people, so a C# IList Neden Kullanmalıyız List here would make sense. When I declare the list object in Group I will use an IList and instantiate it birli a List.

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

By asking for more than you need, you (1) make the caller do unnecessary work to C# IList Nerelerde Kullanılıyor satisfy your unnecessary demands, and (2) communicate falsehoods to the reader. Ask only for what you're going to C# IList Nedir use. That way if the caller saf a sequence, they don't need to call ToList on it to satisfy your demand.

Is IList a good fit for your organisation? If a colleague asks you to change a method signature to use IList instead of List, ask them how they'd C# IList Neden Kullanmalıyız add an element to an IList. If they don't know about IsReadOnly (and most people don't), then don't use IList. Ever.

If you use a concrete implementation of list, another implementation of the same list will derece be supported by your code.

would I run into problems with this? Since could they not pass in an array(that katışıksız a fixed size)? Would it be better maybe for a concrete List?
