I don't totally disagree with the sentiment of over-architecture being a real mesele. However I think that especially in the case of collections that interfaces really shine.

Ayrıca yukarıda anlattığımız IndexOf metodunu Temel liste üzerinden zir listelerdeki elemanlar bağırsakin kullanamazsınız. Ana liste üzerinden zir listelerin index sırasını bulabilirsiniz.
Yes, you may never change that data type from a List but you güç be sure that if you have to. Your code is ready for it.
List implements IList, and so dirilik be assigned to the variable. There are also other types that also implement IList.
In fact, any time you are using reflection IList is more convenient than IList-of-T, since generics and reflection don't play nicely together. It hayat be done, but it is a pain. Unfortunately since IList-of-T doesn't derive from IList there are cases where this kişi eden - but it is a good 95% rule.
And, if you don't even need everything in IList you dirilik always use IEnumerable too. With çağdaş compilers and processors, I don't think there is really any speed difference, so this is more just a matter of C# IList Neden Kullanmalıyız style.
Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.
If you're working within a single method (or even in a single class or assembly in some cases) and C# IList Nasıl Kullanılır 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 you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to C# IList Nasıl Kullanılır a specific implementation, especially if you have no control over who compiles against your code afterward.
Is IList a good fit for your organisation? If a colleague asks you to change a method signature to use IList instead of List, ask them how they'd add an C# IList Nedir element to an IList. If they don't know about IsReadOnly (and most people don't), then don't use IList. Ever.
Unless you have a very compelling reason to do so, your best bet will be to inherit from System.Collections.ObjectModel.Collection since it özgü everything you need.
Encapsulation relies on C# IList Neden Kullanmalıyız telling clients birli little about the implementation of your class kakım possible. If you return a concrete List, you birey't then change to some other better type without forcing all of your clients to re-compile/update.
