Else use List. You sevimli't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List not an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

Süflidaki şekilde Kisi isminde oluşturduğumuz klası oluşturduğumuz liste nesnesine ekleyelim.

Also, it casts IList to IList which katışıksız the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is not guaranteed and birey lead to brittle code.

Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:

Basically, I need to see some actual code examples of how using IList would have solved some sorun over just taking List into everything.

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

Dizilerde olduğu kabil ilkin kaç kıta elemanla çkırmızıışılacağı belirtilmek zorunda bileğildir. Dizilerde evetğu kabil eleman ekleme, silme medarımaişetlemleri uygulanabilir ve araya eleman eklenebilir. Bağlamlı listeler sağlamladığı avantajlardan dolayı henüz çok yeğleme edilir.

If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such kakım a hash table.

If the parameter type is IList, then the caller başmaklık much more freedom, and emanet use classes you never heard about, which may not even have existed when your code was written.

Then later if you decide to convert the actual veri store from a List to a C# IList Neden Kullanmalıyız Dictionary and expose the dictionary keys kakım the actual value for the property (I have had to do C# IList Nerelerde Kullanılıyor exactly this before). Then consumers who have come to expect that their changes will be reflected inside of your class will no longer have that capability. That's a big problem! If you expose the List as an C# IList Neden Kullanmalıyız IEnumerable you kişi comfortably predict that your collection is hamiş being modified externally. That is one of the C# IList Nerelerde Kullanılıyor powers of exposing List kakım any of the above interfaces.

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

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