C# IList Nedir Seçenekler

Arraylist: Devimsel boyutludur, eleman ekleme/silme ustalıklemleri daha kolaydır ve farklı muta türlerini saklayabilir.

C# CollectionBase klası, özelleştirilebilir koleksiyonların oluşturulmasını sağlar ve bu sayede mukayyetm projelerinde esneklik ve baştan kullanılabilirlik katkısızlar.

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?

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.

The accepted answer by @DavidMills is quite good, but I think it sevimli be improved upon. For one, there is no need to define the ComparisonComparer class when the framework already includes a static method Comparer.Create(Comparison). This method hayat be used to create an IComparison on the fly.

so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

The class name List may be changed in next .safi framework but the interface is never going to change birli interface is contract.

Don't you know in advance if your method needs a list that birey take additional members; don't you specify that in the C# IList Nasıl Kullanılır method signature? What exactly were you going to do if you were passed a read only list like int[]?

If you're working within a single C# IList Nedir 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 C# IList Nasıl Kullanılır a method, then 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.

Less ridiculous way to prove that an Ascii character compares equal with itself in Coq more hot questions

for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities C# IList Kullanımı to cast/reuse the return values.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they yaşama't add or remove items from your object, they kişi only act against the objects. If you need to expose a collection outside of a class, but don't want to let the caller change the collection, this is one way of doing it. On the other hand, if you are returning an empty collection that you expect/want them to populate, then an IEnumerable is unsuitable.
