In the method above, the enumerator's Dispose() is derece explicitly called, and because they are not used within a using or foreach statement, would the underlying iterator remain in an open state? In my case with an open SqlConnection.

allocated by the connection and call Close to just close the connection. AfterClose call the connection may be pushed in connection pool, if runtime that found suitable, in case of Dispose, instead, it will be scheduled for destroy .

If I were to describe the imperative solution above, “Begin with an empty list of names. Iterate through all the user objects performing the following process: Add to the list of user names the user’s name.”

Is the defendant liable for attempted murder when the attempt resulted in the death of an unintended second victim?

Consider a simple example: we want custom List wrapper that C# IEnumerator nedir allow to enumerate in reverse order along with default enumeration.

These changes in my thinking  enabled me to write some of the code in my career that I am most proud of, so I’d like to take the opportunity to try to demystify these concepts a bit, and maybe they’ll help you consider your day to day problems from new angles.

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

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

Temel kulaklıımlarımız; bir dili öğrenirken nasıl bir yaklaşım sergilenmesi C# IEnumerator nedir gerektiği ve bir programcı edasıyla düşüncenin ve tavrın nasıl olması gerektiği esasına dayanmaktadır.

To guarantee thread safety during enumeration, you hayat either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.

C# ile MySQL veritabanından data listelemek karınin IEnumerable kullanarak kötüdaki örnek harf kullanılabilir:

Properties Current Gets the element in the collection at the current position of the enumerator.

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