We needed the list indexer infrequently, so the inefficiency was not a sıkıntı. If it had been, we could have provided some other implementation of IList, perhaps as a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

From this it follows that your method implementation birey represent its local variables however you wish. The implementation details are hamiş exposed. Leaving you free to change your code to something better without affecting the people calling your code.

I think that, ideally, the .Safi Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's not too hard to create a couple of methods that will allow you to sort an IList bey you would a List.

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

Yes, you may never change that data type from a List but you gönül be sure that if you have to. Your code is ready for it.

List implements IList, and so yaşama be assigned to the variable. There are also other types that also implement IList.

You kişi look at this argument from several angles including the one of a purely OO approach which says to izlence against an Interface not an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by an Interface in general. If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows what the IList Interface contract adheres to.

The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.

Then later if you decide to convert the actual veri store from a List to a Dictionary and expose the dictionary C# IList Nerelerde Kullanılıyor keys birli the actual value for the property (I have had to do exactly this before). C# IList Neden Kullanmalıyız 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 sorun! If you expose the List as an IEnumerable you birey comfortably C# IList Nasıl Kullanılır predict that your collection is not being modified externally. That is one of the powers of exposing List bey any of the above interfaces.

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

Bu örnekte, Student adında bir sınıf ve StudentCollection C# IList Nedir isminde CollectionBase sınıfından türeyen özel bir derlem sınıfı oluşturduk.

You accept an Interface as a parameter for a method because that allows the caller to submit different concrete types kakım arguments. Given your example method LogAllChecked, the parameter someClasses could be of various types, and for the person writing

There is a complication though that dynamic birey't see explicit implementations, so something hayat implement IList and IList-of-T and yet still be completely unusable from dynamic.
