Greatest Kılavuzu C# IList Kullanımı için

Wiki Article

The above is an IList itself bey this is what seems to be the standard to use with nhibernate. Otherwise I might have returned IEnumberable back but not sure. Still, I güç't figure out what the user would 100% need(that's where returning a concrete katışıksız an advantage over).

Found this thread while I was looking for a solution to the exact sorun described in the original post. None of the answers met my situation entirely, however. Brody's answer was pretty close. Here is my situation and solution I found to it.

Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does not contain an array, so all of a sudden, we had almost no use of the large object heap.

It's more nuanced than that. If you are returning an IList kakım part of the public interface to your library, you leave yourself interesting options to perhaps make a custom list in the future.

Basically, I need to see some actual code examples of how using IList would have solved some sorun over just taking List into everything.

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.

In case of using IList, the caller is always guareented things to work, and the implementer is free to change the underlying collection to any alternative concrete implementation of IList

IList is an Interface, hamiş a class. If you want to initialize it, you need to initialize it to a class that implements IList, depending on your specific needs internally. C# IList Neden Kullanmalıyız Usually, IList is initialized with a List.

; being aware of the definition of the interface ie. all abstract methods that are there to be implemented by any class C# IList Nasıl Kullanılır inheriting the interface. so if some one makes a huge class of his own with several methods besides the ones he inherited C# IList Nedir 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.

IList is hamiş a class; C# IList Nedir it's an interface that classes sevimli implement. The interface itself is just a contract between the consumer of the class and the class itself. This line of code will work:

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

So I have been playing around with some of my methods on how to do this. I am still not sure about the return C# IList Nerelerde Kullanılıyor type(if I should make it more concrete or an interface).
