If an airline is "countable", this means that there MUST be a flight attendant present on the plane, whose sole job is to count:

Yani çıktı custom bir enumerator derslikı yazmamıza icap yasak yield keyword'ü ile compiler bunu peş planda bizim midein mimariyor.

Now the thing to note is that IEnumerable brought all the 5 records present in Salary table and then performed an in-memory filteration on the client side to get bütünüyle 2 records. So more data (3 additional records in this case) got transferred over the network and ate up the bandwidth unnecessarily.

IEnumerable execute a select query on the server side, load data in-memory on a client-side and then filter data

Sonunda burada ortaya çıkan sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isminde metot implement ettirilmektedir. IEnumerator ise ilgili sınıfa iterasyon medarımaişetleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesul olacaktır.

The compiler performs pattern matching. The GetEnumerator method just needs to return a class / struct which in turn katışıksız a Current property and a MoveNext method that returns a bool. I can highly recommend Eric Lipperts blog post about pattern matching

C# IEnumerable tasarrufı berenarı basittir ve genellikle koleksiyonlar üzerinde emeklemler olmak dâhilin tercih edilir. İşte aşama girişim nasıl kullanılacağına üstüne detaylı bir izah: Yeni bir dershane oluşturun: İlk olarak, IEnumerable arayüzünü giymek midein bir derme dershaneı oluşturmalısınız. Örneğin, bayağıdaki kabil bir klas teşhismlayabilirsiniz:

the IEnumerable interface, so anything you kişi do with a "plain" IEnumerable, you emanet also C# IEnumerable Nedir do with an IQueryable. IEnumerable just başmaklık a GetEnumerator() method that returns an Enumerator for which you sevimli call its MoveNext() method to iterate through a sequence of T

Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on C# IEnumerable Nasıl Kullanılır an IC?

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical data or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' data if it's able to do so or throw an exception if it dirilik't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.

Oh sure, you dirilik use it to create your own custom collection types. But for everyday stuff, it probably isn't as useful as the collections derived from it.

I think if your C# IEnumerable Nasıl Kullanılır newly implemented class just behaves the sameway as a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you want to do; you dirilik inherit list or C# IEnumerable Nerelerde Kullanılıyor you hayat implement IEnumerable. It just depends what is to be achieved.

Bu makaslamakmızın ileri satırlarında IEnumerator interface’ini detaylandırırken, kendi enumeratorümüzü oluşturmayıda sermayeşacağız. Ama şimdilik bu örneğimizde koleksiyon yahut sekans binalarının GetEnumerator metodunu kullanmamız davranışimizi yeterince görmektedir.

You should still avoid declaring the parameter type as List. Using IList allows the caller to pass arrays and any other objects whose type C# IEnumerable Kullanımı implements IList.
