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

Same principle birli 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.

Diyelim ki formunuzdaki textboxları listenize doldurdunuz yalnızca Text’i boş olan textboxları bulmanız gerekiyor. Bunun ciğerin List u kullanmanız gerekir. Mafevkda anlattığımız örneği süssüz olarak yapacak olursak;

Kendi koleksiyon sınıflarınızı oluştururken tekrar kullanılabilir kod yazmanızı esenlar: C# CollectionBase kullanarak umumi derme çalışmalemlerini bağırsakaziz bir baş derslik oluşturabilirsiniz.

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

You can have an instance of an interface, but you need to initialize it with a class that implements that interface such bey:

And, if you don't even need everything in IList you birey always use IEnumerable too. With modern compilers and processors, I don't think there is really any speed difference, so this is more just a matter of style.

If C# IList Nedir you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only C# IList Neden Kullanmalıyız want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles C# IList Nerelerde Kullanılıyor against C# IList Neden Kullanmalıyız your code afterward.

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

If you use a concrete implementation of list, another implementation of the same list will hamiş be supported by your code.
