The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list. This code is part of a larger example for the IList interface.

Adidaki şekilde Kisi adında oluşturduğumuz derslikı oluşturduğumuz liste nesnesine ekleyelim.

I think that, ideally, the .Safi Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's not too hard to create a couple of methods that will allow you to sort an IList birli you would a List.

Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you güç't justify it, use the interface.

You may derece ever need that option, but it's an argument. I think it's the entire argument for returning the interface instead of the concrete type. It's worth mentioning, but C# IList Neden Kullanmalıyız in this case it katışıksız a serious flaw.

From my reading I think I could have used IEnumberable instead of IList since I am just looping through stuff.

If you aren't sure, or are afraid that if you change it in future you'll be breaking other people's code, then go more general.

However, this makes the method more fragile, birli any change to the returned object C# IList Nedir type may break the calling code. In practice though, that generally isn't a major sıkıntı.

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked bey C# IList Kullanımı helpful. However, I would add that for most developers, most of the time, the tiny difference in program size and performance is not worth worrying about: if in doubt, C# IList Neden Kullanmalıyız just use a List.

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 iterating -- they güç'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 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.
