Kısaca IEnumerable yapısında filtreleme kârlemleri memory de gestaltlırken, IQueryable da veritabanından kazık filtrelenmiş verileri elde ederiz.
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?
The less popular answer is programmers like to pretend their software is going to be re-used the world over, when infact the majority of projects will be maintained by a small amount of people and however nice interface-related soundbites are, you're deluding yourself.
A List object allows you to create a list, add things to it, remove it, update it, index into it and etc. List is used whenever you just want a generic list where you specify object type in it and that's it.
I tend to follow Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.
The Liskov Substitution Principle (simplified) states that a derived type should be able to be used in place of a base type, with no additional preconditions or postconditions.
Dizilerde olduğu kabilinden özellikle kaç parça elemanla çkızılışılacağı belirtilmek zorunda değildir. Dizilerde evetğu üzere eleman ekleme, silme maslahatlemleri uygulanabilir ve araya eleman eklenebilir. Ilişkilı listeler sağlamladığı avantajlardan dolayı elan çok yeğleme edilir.
If your methods form part of an interface, the methods will need to be defined using types available to that interface.
; 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 ones he inherited from the interface for some addition functionality, and those are C# IList Neden Kullanmalıyız 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.

On the other hand, when returning an object out of a function, you want to give the user the richest possible grup of operations without them having to cast around. So in that case, if it's a List internally, return a copy C# IList Nerelerde Kullanılıyor birli a List.
This is usually guaranteed for a specific implementation of a container (List documentation: "It implements the IList generic interface using an array whose size C# IList Neden Kullanmalıyız is dynamically increased kakım required.").
In particular, IList lets you use the indexer, and add/remove items; things that IEnumerable don't let you do.
Encapsulation relies on telling clients as little about the implementation of C# IList Kullanımı your class birli possible. If you return a concrete List, you yaşama't then change to some other better type without forcing all of your clients to re-compile/update.
