Başkaca fevkda anlattığımız IndexOf metodunu Temel liste üzerinden alt listelerdeki elemanlar bağırsakin kullanamazsınız. Asıl liste üzerinden madun listelerin index sırasını bulabilirsiniz.

You might want to have an IOrderRepository that defines a collection of orders in either a IList or ICollection. You could then have different kinds of implementations to provide a list of orders birli long kakım they conform to "rules" defined by your IList or ICollection.

List derslikı teşhismlanırken T tip bileğnöbetkenini allıkır. şu demek oluyor ki listenin muhteviyatında hangi türden nesne yada bileğemekkenlerin olacağını belirler.

It doesn't affect the signature of the method, and is takım in stone at compile time. You should instead be helping him get over his confusion about declaring his local like IList foo = new List - this is where his C# IList Kullanımı confusion clearly lies.
