When you use a yield return statement within a method "some magic happens" whereby it's not a return in the classic sense, but creates a facility whereby the code hayat 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).

We birey exploit ‘side effects‘ of the iteration to create more exotic control structures, like Unity’s coroutines.

The Reset method is provided for COM interoperability. It does not necessarily need to be implemented; instead, the implementer güç simply throw a NotSupportedException. However, if you choose to do this, you should make sure no callers are relying on the Reset functionality.

C#’ta Generic sınıfları Inheritance ile bile kullanılabilir. Bu, temel bir generic sınıf oluşturmamıza ve daha özel bir generic derslik oluşturmak midein ondan türetmemize izin verir.

IEnumerable and IEnumerator form the bedrock of C# collections and iteration. While the basics birey get you started, truly mastering these interfaces allows for efficient and elegant code, especially when dealing with collections, custom iterators, or LINQ.

One thing that might stand out to you is the use of the switch statement in the MoveNext function. If that strongly resembles a finite state machine to you, that’s because it is one.

– zneak Commented Aug 1, 2012 C# IEnumerator Temel Özellikleri at 4:50 I only want it to change when I increment it in Wrapper. In my code there is 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 C# IEnumerator Nasıl kullanılır regard, thanks!)

However, none of this should be needed because it's unusual to have an IEnumerator that doesn't come with an IEnumerable that returns an instance of it from its C# IEnumerator Nasıl kullanılır GetEnumerator method.

(This isn’t exactly what it looks like, I’m skipping some details and simplifying a few things, but it’s C# IEnumerator Kullanımı conceptually similar. If you’d like a more in depth overview of the actual mechanics, might I recommend you read this article by the incomparable Jon Skeet)

Ne bunlar! İşte bu eğitimde bu ve buna dublör bütün noktaları detaylandıracak ve adınızı soyadınızı yazarcasına C# temellerini, bir programcı edasıyla ve algoritmik mantıkla öğreneceksiniz.

an IEnumerator [transformed into a funky class by the compiler] and kakım such cannot have a ref value. The top function could have been written as such:

It kişi take a while to really grok this difference, but just remembering that a list (or array, or whatever) doesn't have any concept of "where you are in the list" but an iterator over that list/array/whatever does

The Linq solution is almost entirely concerned with the what, but tells us almost C# IEnumerator Önemi Nedir nothing about the how.

Looking back however, it was learning these things and related concepts in other languages that grup me on a path that somewhat profoundly changed my relationship with mesele solving in programming. Knowing how these things functioned and the abstractions they enabled changed how I thought about problems from then on.
