şu demek oluyor ki IEnumerable mimarisında filtreleme işçiliklemleri memory bile binalırken, IQueryable da veritabanından kazık filtrelenmiş verileri elde ederiz.
IList is an interface so you gönül inherit another class and still implement IList while inheriting List prevents you to do so.

Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
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.
Buraya özen etmenizi istiyorum. Liste tipine textbox dedik ve listeye textbox eklerken de dikme nesne adını verdik. şu demek oluyor ki text özelliğini felan vermedik. Direk nesnenin kendisini verdik. Şimdi bu maslahatin kıvrak kısaca şu;
use LINQ to perform the conversion of your existing List when you return it - but it would be better to just create a more appropriate type to start with, C# IList Nedir as shown above.
However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed bey well. This is because a class adhering to IList guarantees a certain C# IList Neden Kullanmalıyız behavior that is not 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 the developer a lot

Of course that only need apply to methods that are externally visible (i.e. public methods). I personally use interfaces even in internal code, but birli you are able to change all the code yourself if you make breaking changes it's derece strictly necessary.
You might want to have an IOrderRepository that defines a C# IList Nedir collection of orders in either a IList or ICollection. You could then have different kinds of implementations to provide a list of orders kakım long kakım they conform to "rules" defined by your IList or ICollection.
Dizin tarafından erişilebilen nesnelerin kesin olarak belirlenmiş bir listesini simgeleme paha. Listeleri kontrol, sıralama ve işleme şekilleri sağlamlar.
This works, because only the outer list is created in the first place. You emanet then insert individual items that C# IList Nasıl Kullanılır are compatible with IList:
