When you use a yield return statement within a method "some magic happens" whereby it's hamiş a return in the classic sense, but creates a facility whereby the code dirilik resume from where it left off (calling for the next item out of the returned enumerator will cause the code to resume from after the yield, with all the state it had before, rather than starting over).
it dirilik be useful to use the iterators directly. A good example is when trying to "pair up" two different sequences. For example, suppose you receive two sequences - one of names, one of ages, and you want to print the two together. You might write:
Bu şekilde derlem yürekindeki elemanlara sırasıyla erişim sağlanabilir. Süflida bu yararlanmaı gösteren bir örnek bulunmaktadır:
Comparing those three descriptions, we sevimli see that the imperative description is very concerned with how we are performing the operation, and what we are trying to do takes a bit more effort to work out.
To grup Current to the first element of the collection again, you güç call Reset, if it's implemented, followed by MoveNext. If Reset is not implemented, C# IEnumerator Nasıl kullanılır you must create a new enumerator instance to return to the first element of the collection.
Hi all i searched for IEnumerator but could derece get to understand it.it would be great help if anyone helps me.
– zneak Commented Aug 1, 2012 at 4:50 I only want it to change when I increment it in Wrapper. In my code there is C# IEnumerator Kullanımı a value that needs to be incremented once and only once before the code is called, so I wanted to wrap it up so I wouldn't accidentally forget to do that at some point and introduce hard to trace bugs. (Updated the question to be a bit clearer in that regard, thanks!)
String Replace Kullanımı: String içinde ki bir C# IEnumerator nerelerde kullanılıyor metni veya karakteri bir sair tekst yahut şemail ile tebdil etmek muhtevain kullanılır.
This is pretty simple (if a touch verbose). You might think of it C# IEnumerator nedir bey representing the state of a for loop’s C# IEnumerator nerelerde kullanılıyor header; we track the index, progression and end condition of the iteration.
/// p adlı parametrenin Salary(Maaş) değerinden p2 parametresindeki maaş değeri
In fact, you might even think of methods that contain yield as a compact way of writing state machines. We’ll explore this more in later articles.
Enumerators yaşama be used to read the data in the collection, but they cannot be used to modify the underlying collection.
This is a fine way to do it, but it is a fair amount of code to express something that is pretty trivial. Here’s the same basic solution using Linq:
IEnumerable interface’i, enumerated bir nesne karınin bir interface tarif etmek ciğerin kullanılabilir:
