I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method birli well birli casting to a List but none of these seemed overly elegant.

Same principle as before, reversed. Offer the bare asgari that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

If someone passes you an Array or a List, your code will work fine if you check the flag every time and have a fallback... But really; who does that?

Sevimli a unique position be deduced if pieces are replaced by checkers (hayat see piece color but derece type)

Kemiksiz 4.6 (and it will likely be caught by the compiler). But there kişi be more insidious cases, such bey passing a C# array birli a IList. I am hamiş sure everyone is aware arrays implement IList, which means support for Add should not be assumed.

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you sevimli't justify it, use the interface.

use LINQ to perform the conversion of your existing List when you return it - but it would be C# IList Nerelerde Kullanılıyor better to just create a more appropriate type to start with, as C# IList Nedir shown above.

Then when you need "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and if you need more then extend...

; 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 Kullanımı 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.

The Cast function is just a reimplementation of the extension method that comes with 3.5 written birli a düzgülü static method. It is quite ugly and verbose unfortunately.

On the other hand, when returning an object out of a function, you want to give the user C# IList Nerelerde Kullanılıyor the richest possible takım of operations without them having to cast around. So in that case, if it's a List internally, return a copy bey a List.

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

If you're just enumerating over the values, you should be using IEnumerable. Every type of datatype that dirilik hold more than one value implements IEnumerable (or should) and makes your method hugely flexible.

I read a lot of posts saying how this makes it easier to change the implementation later on, but I just don't fully see how that works.
