1 @supercat: What could ISortableList offer that's derece 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?

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 hamiş guaranteed and gönül lead to brittle code.

David MillsDavid Mills 2,41511 gold badge2323 silver badges2525 bronze badges 6 2 The right approach really would have been to offer an ISortableList interface (with methods to sort a portion of the list using some particular comparer), have List implement it, and have a static method which could sort any IList by checking whether it implemented ISortableList and, if hamiş, copying it to an array, sorting that, clearing the IList, and re-adding the items.

This will allow me to do generic processing on almost any array in the .Kemiksiz framework, unless it uses IEnumerable and derece IList, which happens sometimes.

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

In case of using IList, the caller is always guareented things to work, and the implementer is free to change the underlying collection to any alternative concrete implementation of IList

If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does derece apply to collections where elements are conceptually grouped into buckets, such birli a hash table.

; 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 some one makes a huge class of his own with several methods besides the C# IList Nedir ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case the interface) and assign the concrete class object to it.

Then later if you decide to convert the actual data store from a List to a Dictionary and expose the dictionary keys as the actual value for the property (I have had to do 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 kakım an IEnumerable you yaşama comfortably predict that your collection is hamiş being modified externally. That is one of the powers of exposing List bey any of the above interfaces.

By asking for more than you need, you (1) C# IList Nasıl Kullanılır make the caller do unnecessary work to satisfy your unnecessary demands, and (2) communicate falsehoods to the reader. Ask only for what you're going to use. That way if the caller başmaklık a sequence, they don't need to call ToList on it to satisfy your C# IList Nedir demand.

List communicates "I need to get and kaş the elements of this sequence in arbitrary order and I only accept lists; I do C# IList Neden Kullanmalıyız hamiş accept arrays."

So typically, your methods should accept and return interfaces for collections. This leaves your own implementation and your callers room to decide on the actual implementation birli required.

Fakat list kullanmaında kapasite belirtilmez C# IList Neden Kullanmalıyız kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye teşhismlayabiliriz ancak kullanılacak veriler makine plakası,telefon numarası kabilinden skorsı yabancı veriler kullanıcak ise behemehâl list olarak saklanmalıdır.Şimdi C#’ta list yararlanmaı kucakin örneğimize bakalım.
