C# List bâtınindeki verileri yazdırmak sinein aşağıdaki iki döngüden biri kullanılarak değerleri ekrana yazdırma konulemi binalabilir.
Edit: You do need to be quick to get answers in here. Birli I presented a slightly different syntax to the other answers, I will leave my answer - however, the other answers presented are equally valid.
A List object allows you to create a list, add things to it, remove it, update it, index into it and etc. List is used whenever you just want a generic list where you specify object type in it and that's it.
The accepted answer by @DavidMills is quite good, but I think it can be improved upon. For one, there is no need to define the ComparisonComparer class when the framework already includes a static method Comparer.Create(Comparison). This method yaşama be used to create an IComparison on the fly.
The speed difference is sufficiently great that in many cases it may be faster to copy a list to an array, sort the array, and copy the list back, than to try to have a sort routine process the list in place.
class Kisi string ad; string soyad; public string Ad get return ad; C# IList Nedir seki ad = value; public string Soyad get return soyad; grup soyad = value;
; being aware of the definition of the interface ie. all abstract methods that are there to be implemented by any class inheriting the interface. so C# IList Neden Kullanmalıyız if some one makes a huge class of his own with several methods besides the ones he inherited from C# IList Nedir the interface for some addition functionality, and those are of no use to you, its better to use a reference C# IList Nasıl Kullanılır to a subclass (in this case the interface) and assign the concrete class object to it.
List implements those büyük anne methods (hamiş including extension methods), on bütünüyle of that it has about 41 public methods, which weighs in your consideration of which one to use in your application.
However, this makes the method more fragile, birli any change to the returned object type may break the calling code. In practice though, that generally isn't a major sorun.
The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it özgü to use List.
for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.
IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for C# IList Nedir accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property kakım a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on the fact that they kişi modify the list.
