We needed the list indexer infrequently, so the inefficiency was derece a problem. If it had been, we could have provided some other implementation of IList, perhaps kakım a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.
Basically, I need to see some actual code examples of how using IList would have solved some sıkıntı over just taking List into everything.
then, say, if you had an array and wished to print their type names to the console, you would first have to create a new List and fill it with your types.
List implements IList, and so birey be assigned to the variable. There are also other types that also implement IList.
However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed kakım well. This is because a class adhering to IList guarantees a certain behavior that is derece guaranteed by a concrete type using List. Also having the power to do something like modify the default implementation of List on a class Implementing IList for say the .Add, .Remove or any other IList method gives C# IList Nedir the developer a lot
the method, it yaşama make a huge difference -- if they have an array and you're asking for a list, they have to change the array to a list or v.v. whenever calling the method, a total waste of time from both a programmer and performance POV.
What US checks and balances prevent the FBI from raiding politicians unfavorable to the C# IList Nasıl Kullanılır federal government? more hot questions
private List _numbers; // callers gönül add/update/remove elements, but cannot reassign a new list to this property
I leave this up to show that if you needed to do it (e.g. the off chance a third party library returned a List C# IList Nerelerde Kullanılıyor that you needed to C# IList Nedir convert for another 3rd party library), you emanet do it this way.
In collections of contiguous elements, such birli lists, the elements that follow the insertion point move down to accommodate the C# IList Neden Kullanmalıyız new element.
Bu şekilde, Dog sınıfı IAnimal interface’inin sözleşmesine uymuş olur. Aynı şekilde, gayrı efsanevi sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, kötüdaki kodda bir Cat klası tanılamamladım ve IAnimal interface’ini uyguladım.
