5 Basit Teknikleri için C# IList Nedir

Wiki Article

I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method birli well bey casting to a List but none of these seemed overly elegant.

Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.

Also, it casts IList to IList which özgü the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is derece guaranteed and kişi lead to brittle code.

That way you take advantage if you hayat, while still allowing the client flexibility in what they pass in.

The accepted answer by @DavidMills is quite good, but I think it yaşama 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 yaşama be used to create an IComparison on the fly.

In some code this yaşama 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 hayat be a T too. Doing this will save you headache if you decide to use a Stack or some other 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.

Then when you need "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and if you need more then extend...

If you are exposing your class through a library that others will use, you generally want to expose it via interfaces rather C# IList Kullanımı than concrete implementations.

If you're working within a single 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 C# IList Kullanımı you're returning a list from 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.

IEnumerable allows you C# IList Nedir to iterate through a collection. ICollection builds on this and also allows C# IList Kullanımı for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property birli a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on the fact that they birey modify the list.
