The above is an IList itself kakım this is what seems to be the standard to use with nhibernate. Otherwise I might have returned IEnumberable back but derece sure. Still, I hayat't figure out what the user would 100% need(that's where returning a concrete başmaklık an advantage over).
Then the person calling the method is free to call it with any veri type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.
Diyelim ki formunuzdaki textboxları listenize doldurdunuz sadece Text’i boş olan textboxları bulmanız gerekiyor. Bunun bâtınin List u kullanmanız gerekir. Yukarıda anlattığımız örneği olağan olarak meydana getirecek olursak;
Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:
In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.
IList on the other hand is an Interface. Basically, if you want to create your own custom C# IList Neden Kullanmalıyız List, C# IList Kullanımı say a list class called BookList, then you kişi use the Interface to give you basic methods and structure to your new class. IList is for C# IList Nedir when you want to create your own, special sub-class that implements List.
You are most often better of using the most general usable type, in this case the IList or even better the IEnumerable interface, so that you can switch the implementation conveniently at a later time.
class Kisi string ad; string soyad; public string Ad get return ad; grup ad = value; public string Soyad get return soyad; takım soyad = value;
In VS2008, when I click on the service reference and select "Configure Service Reference", there is an option to choose how the client de-serializes lists returned from the service.
Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.
IList is hamiş a class; it's an interface that classes güç implement. The interface itself is just a C# IList Nedir contract between the consumer of the class and the class itself. This line of code will work:
Returning a read-only interface such bey IEnumerable is often the way to go for veri-retrieval methods. Your consumer yaşama project it into a richer type birli-needed.
for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.
Fakat C# IList Nasıl Kullanılır list tasarrufında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye teşhismlayabiliriz fakat kullanılacak veriler makine plakası,telefon numarası gibi adetsı bilinmedik veriler kullanıcak ise behemehâl list olarak saklanmalıdır.Şimdi C#’ta list kullanımı yürekin örneğimize bakalım.
