Arraylist: Hareketli boyutludur, eleman ekleme/silme hizmetlemleri elan kolaydır ve farklı muta türlerini saklayabilir.

Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.

Diyelim ki formunuzdaki textboxları listenize doldurdunuz sadece Text’i boş olan textboxları bulmanız gerekiyor. Bunun muhtevain List u kullanmanız gerekir. Fevkda anlattığımız örneği kıytırık olarak meydana getirecek olursak;

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.

Buraya özen etmenizi istiyorum. Liste tipine textbox dedik ve listeye textbox eklerken de direk nesne adını verdik. Doğrusu text özelliğini felan vermedik. Direk nesnenin kendisini verdik. Şimdi bu işlemin filinta şu demek oluyor ki şu;

Whether you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created -- this is an API design C# IList Nasıl Kullanılır decision, and there's no hard and fast rule. You have to weigh their ability to make full use of the object against their ability to easily use C# IList Neden Kullanmalıyız a portion of the objects functionality (and of course whether you WANT them to be making full use C# IList Nedir of the object).

You would because defining an IList or an ICollection would open up for other implementations of your interfaces.

If 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 C# IList Nerelerde Kullanılıyor you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked kakım helpful. However, I would add that for most developers, most of the time, the tiny difference in yetişek size and performance is hamiş worth worrying about: if in doubt, just use a List.

Yaşama a unique position be deduced if pieces are replaced by checkers (can see piece color but hamiş type)

It doesn't affect the signature of the method, and is grup in stone at compile time. You should instead be helping him get over his confusion about declaring his local like IList foo = new List - this is where his confusion clearly C# IList Nerelerde Kullanılıyor lies.
