This is to prevent old-calls from the previous level affecting the new loaded level.

The enumerator does not have exclusive access to the collection; therefore, enumerating through a collection is intrinsically not a thread-safe procedure.

That's good to know. Also if we implement IEnumerator we have to implement Dispose method. Birli you said, if sequence is generated, it saf to be disposed off. Thanks a lot!

Comparing those three descriptions, we emanet 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.

şayet ki siz “var” harcamak istiyorsanız GetEnumerator metodunun son dkarşıüş tipini adidaki kabil generic IEnumerator olarak tanımlamanız gerekmektedir.

My answer will cause the code to hamiş compile and therefore I have less chance of shipping a bug in my code, kakım it would signal to me that I am using the wrong type.

Take a moment to consider these classes for a bit. There are some interesting and powerful properties:

C# Formlar arası kararsız ile done sevk konusu en pıtrak kullanılan yöntemdir. Genellikle C# IEnumerator Kullanımı 2 form ortada kullanılır. Şahsen ben en şu denli 2 form ortada kullanılmasını referans ediyorum. Nasıl istisnalar nanay değil.

Yineleyici yöntemlerinde önemli bir kısıtlama vardır: aynı yöntemde hem fehva returnyield return hem de fehva olamaz. Zirdaki kod derlenmez:

The compiler performs pattern matching. The GetEnumerator method just needs to return a class / struct which in turn özgü a Current property and a MoveNext method that returns a bool. C# IEnumerator neden kullanmalıyız I birey highly recommend Eric Lipperts blog post about pattern matching

Bir sınıfa IEnumerable interface'i implement geçirmek ummak, o derslikın IEnumerator nesnesi döndüreceği mazmunına gelir.
