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.

The enumerator does hamiş have exclusive access to the collection; therefore, enumerating through a collection is intrinsically hamiş a thread-safe procedure.

Explicit casts are never compile-time proof. Instead assign/returning array kakım IEnumerable uses the implicit cast which is compile-time proof.

Kakım a bonus, you will notice that all the variables are nicely encapsulated in the Method, kakım opposed to in free floating fields.

Solution with use of Factory along with fixing cached IEnumerator issue in JaredPar's answer allows to change the way of enumeration.

Hi all i searched for IEnumerator but could derece get to understand it.it would be great help if anyone helps me.

        /// Eğer p parametresinde Name ile p2 parametresindeki Name müsavi ise True dönecek.

Just in the same way a function of type List just returns a List - albiet the compiler will 'automagically' create the IEnumerator class for you in C# IEnumerator Kullanımı the former case. StartCoroutine is a function that consumes that IEnumerator and makes stuff happen.

If I were to describe the Linq solution: “Given a seki of users, select from each their username.”

C# form kapanırken bilgi irsal teamüllemi de sık kesif geçişsiz olan bir işçiliklemdir. Örnek bir senaryo vermem icabında;

The enumerator produced by an iterator block implements IDisposable. Calling Dispose() on it ensures that all the finally blocks in the C# IEnumerator nerelerde kullanılıyor iterator block are executed, including finally blocks that come from using statements.

IEnumerable already derives from IEnumerable so there's no need C# IEnumerator neden kullanmalıyız to do any conversion. You yaşama simply cast to it...well actually it's implicit no C# IEnumerator neden kullanmalıyız cast necessary.

IEnumerable is an interface that defines C# IEnumerator Nasıl kullanılır one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable hayat be used with a foreach statement.
