Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:
In this specific case since you're essentially talking about a language construct, not a custom one it generally won't matter, but say for example that you found List didn't support something you needed.
In some code this kişi be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to call this seki of methods, no other contract implied."
Object sevimli be a T too. Doing this will save you headache if you decide to use a Stack or some other veri structure further down the road. If all you need to do in the function is foreach through it, IEnumerable is really all you should be asking C# IList Kullanımı for.
Don't you know in advance if your method needs a list that kişi take additional members; don't you specify that in the method signature? What exactly were you going to do if you were passed a read only list like int[]?
If you are exposing your class through a library that others will use, you generally want to expose it via interfaces rather than concrete implementations.
Modülerlik: Yazılım projelerinde modüler bir yaklaşım sunarak harf yineını azaltır ve hizmetı kolaylaştırır.
On the other hand, when returning an object out of a function, you want to give the user the richest possible takım of operations without them having to cast around. So in that case, if it's a C# IList Neden Kullanmalıyız List internally, return a copy bey a List.
Brad LeachBrad Leach 17k1818 gold badges7373 silver badges8888 bronze badges 1 3 It will create a new enumerable, which may hamiş be desirable in some scenarios. You cannot sort an IList in-place through the interface except by using ArrayList.Adapter method in my knowledge.
for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.
For instance, if you return an IEnumerable, then you are limiting them to C# IList Nasıl Kullanılır iterating -- they yaşama't add or remove items from your object, they güç only act against the objects. If you need to expose a collection outside of a class, but don't want to let C# IList Neden Kullanmalıyız the caller change the collection, this is one way of C# IList Kullanımı 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.
