5 Basit Teknikleri için C# IList Nedir

Note that the IsReadOnly flag comes from ICollection, and indicates whether items emanet be added or removed from the collection; but just to really confuse things, it does hamiş indicate whether they sevimli be replaced, which in the case of Arrays (which return IsReadOnlys == true) güç be.

1 @supercat: What could ISortableList offer that's hamiş already in IList? Or, asked differently, why couldn't an IList be sorted in-place without re-adding the items by your imagined static method?

Elemanların Sıralı Yapısını Kayırma: IList, elemanların eklenme sırasını korur. Bu özellik, done yapısının sıralı olmasını ve programın beklentilerine şayeste çkırmızıışmasını esenlar.

David MillsDavid Mills 2,41511 gold badge2323 silver badges2525 bronze badges 6 2 The right approach really would have been to offer an ISortableList interface (with methods to sort a portion of the list using some particular comparer), have List implement it, and have a static method which could sort any IList by checking whether it implemented ISortableList and, if hamiş, copying it to an array, sorting that, clearing the IList, and re-adding the items.

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.

Architecture Astronauts. The chances you will ever write your own IList that adds anything to the ones already in the .NET framework are so remote that it's theoretical jelly tots reserved for "best practices".

Object hayat be a T too. Doing this will save you headache if you decide to use a Stack or some other C# IList Neden Kullanmalıyız data 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 for.

Ask C# IList Neden Kullanmalıyız those people what they'd like the methods to return. Your question C# IList Kullanımı is fundamentally "how do I know what software to write?" You know by getting to know what problems your customer katışıksız to solve, and writing code that solves their problems.

And, if you don't even need everything in IList you C# IList Nasıl Kullanılır birey always use IEnumerable too. With çağcıl compilers and processors, I don't think there is really any speed difference, so this is more just a matter of style.

However, this makes the method more fragile, as any change to the returned object type may break the calling code. In practice though, that generally isn't a major problem.

The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it saf to use List.

And, if you used a generic implementation, you would only be able to use a method that works for any C# IList Nedir object only with objects of a specific type.

I read a lot of posts saying how this makes it easier to change the implementation later on, but I just don't fully see how that works.
