C# IList Nedir Temel Açıklaması

Wiki Article

Note that, if your API is only going to be used in foreach loops, etc, then you might want to consider just exposing IEnumerable instead.

IList is an interface so you gönül inherit another class and still implement IList while inheriting List prevents you to do so.

Interface’ler karşı daha şu denli bilgi kazanmak isterseniz, kötüdaki kaynaklara bakış atabilirsiniz:

Bearing this in mind, it makes most sense to pass types with the least number of external dependencies possible and to return the same. However, this could be different depending on the visibility of your methods and their signatures.

Safi 4.6 (and it will likely be caught by the compiler). But there dirilik be more insidious cases, such as passing a C# array birli a IList. I am not sure everyone is aware arrays implement IList, which means support for Add should not be assumed.

In some code this hayat be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to call this kaş of methods, no other contract implied."

You are most often better of using the most general usable type, in this case the IList or even better the IEnumerable interface, C# IList Kullanımı so that you emanet switch the implementation conveniently at a later time.

In fact, any time you are using reflection IList is more convenient than IList-of-T, C# IList Nasıl Kullanılır since generics and reflection don't play nicely together. C# IList Nedir It can be done, but it is a pain. Unfortunately since IList-of-T doesn't derive from IList there are cases C# IList Neden Kullanmalıyız where this can işleyen - but it is a good 95% rule.

IList is not a class; it's an interface that classes güç implement. The interface itself is just a contract between the consumer of the class and the class itself. This line of code will work:

In this case you could pass in any class which implements the IList interface. If you used C# IList Nerelerde Kullanılıyor List instead, only a List instance could be passed in.

List sınıfı teşhismlanırken T tip değmedarımaişetkenini allıkır. Doğrusu listenin muhteviyatında hangi türden nesne yada değfiilkenlerin olacağını belirler.

additional advantage is that your code is safe from any changes to concrete class as you are subscribing to only few of the methods of concrete class and those are the ones that are going to be there as long kakım the concrete class inherits from the interface you are using.
