C# List mideindeki verileri yazdırmak için dundaki iki döngüden biri kullanılarak bileğerleri ekrana yazdırma mesleklemi binalabilir.
Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, not add or remove. Accepting an interface kakım a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."
The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.
The preceeding line of code will work, but you will only have the members of IList available to you instead of the full grup from whatever class you initialize.

Most app-level code (i.e. the everyday code that ou write for your application) should probably focus on the generic C# IList Kullanımı versions; however there is also a lot of infrastructure code around that must use reflection.
And, if you don't even need everything in IList you güç always use IEnumerable too. With çağcıl compilers and C# IList Neden Kullanmalıyız processors, I don't think there is really any speed difference, so this is more just a matter of style.

Obviously if you are being asked C# IList Nasıl Kullanılır which you use in an interview, you say IList, smile, and both look pleased at yourselves for being so clever. Or for a public facing API, IList. Hopefully you get my point.
Şimdi beraber bir örnek yapalım. Bir birlik yönlü bağlı liste oluşturalım ve bu listeye kazara olarak eleman ekleyelim. Bu eklediğimiz elemanları da ekrana yazdıralım:
You accept an Interface birli a parameter for a method because that allows the caller to submit different concrete types as arguments. Given your example method LogAllChecked, the parameter someClasses could be of various types, and for the person writing
additional advantage is that your code is safe from any changes to concrete class C# IList Nasıl Kullanılır birli you are subscribing to only few of the methods of concrete class and those are the ones that are going to be there C# IList Kullanımı as long as the concrete class inherits from the interface you are using.
