Note that the IsReadOnly flag comes from ICollection, and indicates whether items kişi be added or removed from the collection; but just to really confuse things, it does not indicate whether they can be replaced, which in the case of Arrays (which return IsReadOnlys == true) can be.
Found this thread while I was looking for a solution to the exact problem described in the original post. None of the answers met my situation entirely, however. Brody's answer was pretty close. Here is my situation and solution I found to it.
Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does hamiş contain an array, so all of a sudden, we had almost no use of the large object heap.
If you think that interfaces are useful only for building over-sized, grandiose architectures and have no place in small shops, then I hope that the person sitting across from you in the interview isn't me.
I tend to follow C# IList Nasıl Kullanılır Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.
In some code this yaşama 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 set of methods, no other contract implied."
The cost to do this is C# IList Neden Kullanmalıyız minimal, why hamiş save yourself the headache later? It's what the interface principle is all about.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
This example also tells you that there may be situations when you need to specify the implementation, derece C# IList Nasıl Kullanılır the interface, in the argument list: In C# IList Kullanımı this example, whenever you require a particular access performance characteristic.
You would because defining an IList or an C# IList Neden Kullanmalıyız ICollection would open up for other implementations of your interfaces.
Bir ahir elementin varlığını sınayan MoveNext ve muteber elementi veren GetCurrent metodlarına sahiptir.
The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it özgü to use List.
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.
Ancak list yararlanmaında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye tanılamamlayabiliriz fakat kullanılacak veriler makine plakası,telefon numarası üzere adetsı adsız veriler kullanıcak ise kesinlikle list olarak saklanmalıdır.Şimdi C#’ta list kullanımı sinein örneğimize bakalım.
