, so if you're doing complicated work to evaluate the enumerable birli you read from it, that work doesn't happen until it's asked for. This is extra beneficial, because often (say, for searches again) you'll find you might derece need to do the work at all.

Bir yetişek ortamında çeşitli done koleksiyonları kullanıldığında, bu koleksiyonlardaki verilere erişmek ve işlem edinmek gereklidir. IEnumerator, bu noktada devreye girerek koleksiyonların elemanlarını bir numara yek dolaşmamızı ve iş yapmamızı sağlar.
Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach as one example.
B. IEnumerator sevimli remember the current index when we pass from one method to another (it start working with current index) but IEnumerable hayat't remember the index and it reset the index to beginning. More in this video
C# IEnumerable kullanmanın birbunca avantajı vardır ve bu avantajlar sebebiyle yazılı sınavm geliştiricilerin sıkça tercih ettiği bir arayüz olmuştur. C# IEnumerable Kullanımı İşte detaylı olarak niçin C# IEnumerable kullanmalıyız:
What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?
Else use an IEnumerable. The default should be to use the on-demand evaluation in the second example, bey that generally uses less memory, unless there is a specific reason to store the results in a list.

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical data or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' veri if it's able to do so or throw an exception if it sevimli't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.
Bu alanda yahut C# IEnumerable Nedir başka bir alanda, benim ve özge yardımcı insanların paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm altına girmeniz medlulına gelmemektedir.
Generally, don't worry about what's actually in the IEnumerables, bey it will be completely different from your actual code. Only worry about the actual output when you iterate C# IEnumerable Kullanımı over it :)

Unfortunately C# IEnumerable Temel Özellikleri IEnumarable seems to be blindly used kakım the lowest interface which now causes problems with asynchronous data manipulation (e.
In addition to all the answers posted above, here is my two cents. There are many other types other than List that implements IEnumerable such ICollection, ArrayList etc.
