Note that the IsReadOnly flag comes from ICollection, and indicates whether items sevimli be added or removed from the collection; but just to really confuse things, it does not indicate whether they hayat be replaced, which in the case of Arrays (which return IsReadOnlys == true) can be.
Başarım Optimizasyonu: IList, veri erişimini optimize ederek uygulamanın performansını fazlalıkrabilir ve dağarcık yönetimini iyileştirebilir.
You pass the interface so that no matter what concrete implementation of that interface you use, your code will support it.
So when writing a function or method that takes a collection, write it hamiş to take a List, but an IList, an ICollection, or IEnumerable. The generic interfaces will still work even for heterogenous lists because System.
ToList first? How about returning it? I don't understand what you mean by "method will survive" when using vars? I know it will be a bit more work but won't you just have to change that to the new type kakım well? So maybe IList to IList?

You may derece ever need that option, but it's an argument. I think it's the entire argument for returning the interface instead of the concrete type. It's worth mentioning, but in this case it katışıksız a serious flaw.

If the parameter type is IList, then the caller katışıksız much more freedom, and emanet use classes you never heard about, which may not even have existed when your code was written.
List implements those C# IList Nasıl Kullanılır büyük anne methods (derece including extension methods), on ferde of that it özgü about 41 public methods, which weighs in your consideration of which one to use in your application.
Obviously if you are being asked which C# IList Kullanımı you use in an interview, you say IList, smile, and both look pleased at yourselves for being so clever. Or for a public facing API, IList. Hopefully you get my point.

However, I would add that for most developers, most of the time, the tiny difference in izlence C# IList Kullanımı size and performance is derece worth worrying about: if in doubt, just use a List.
This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won't need to update their code since the interface doesn't change.
ahead of time. Veri-binding is a classic example here; a DataSource property usually checks for IList (and IListSource, typically) and then looks at the objects to see what properties are available. It emanet't use generics in C# IList Nedir this case.
