I know there özgü been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.
1 @supercat: What could ISortableList offer that's hamiş already in IList? Or, asked differently, why couldn't an IList be sorted in-place without re-adding the items by your imagined static method?
I think that, ideally, the .Kupkuru 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 hamiş too hard to create a couple of methods that will allow you to sort an IList birli you would a List.
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.

Convert your IList into List or some other generic collection and then you yaşama easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)
Most app-level code (i.e. the everyday code that ou write for your application) should probably C# IList Nedir focus on the generic versions; C# IList Kullanımı however there is also a lot of infrastructure code around that must use reflection.
; being aware of the definition of the interface ie. all abstract methods that are there to be implemented by any class inheriting the interface. so if C# IList Kullanımı some one makes a huge class of his own with several methods besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use C# IList Kullanımı a reference to a subclass (in this case the interface) and assign the concrete class object to it.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues kakım the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
I know that IList is the interface C# IList Neden Kullanmalıyız and List is the concrete type but I still don't know when to use each one. What I'm doing now is if I don't need the Sort or FindAll methods I use the interface. Am I right? Is there a better way to decide when to use the interface or the concrete type?
Bu örnekte, Student isminde bir sınıf ve StudentCollection adında CollectionBase klasından türeyen özel bir derme sınıfı oluşturduk.
In collections of contiguous elements, such kakım lists, the elements that follow the insertion point move down to accommodate the new element.
ahead of time. Data-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 hayat't use generics in this case.
