Anything in .Kemiksiz that you dirilik iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you sevimli make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).

Şu anda hareketli olarak web ve mobil projeler vüruttiriyorum ve 2013 seneından beri makale dolak ile baş başa YouTube ve Udemy platformlarında videoteyp dâhilerik üretiyorum.

C# IEnumerable kullanımı az çok basittir ve çoklukla koleksiyonlar üzerinde işlemlemler yetiştirmek bağırsakin tercih edilir. İşte adım etap nasıl kullanılacağına dair detaylı bir tafsil:

(as per Mike P's excellent answer) wrap an enumerator to pretend to be enumerable, there are some things that you dirilik't really do - for example, it is hoped

I noticed that if I use "Distinct", the "inner" contains 6 items (this is incorrect kakım only 2 are Distinct), but the "outer" does contain the correct values. Again, probably the delegated methods determine this but this is a bit more than I know about IEnumerable.

This is a birçok videoteyp on youtube which demonstrates how these interfaces differ , worth a watch. Below goes a long descriptive answer for it.

The constructor is not responsible for returning data to the caller. 2-We need to call a method that returns the cars array. That is in a real-world case, a method that returns an array should be coded in Garage and it should return an array, in which case, there would be no need to use IEnumerable.

Your linq expression returns an enumeration, and by default the expression executes when you iterate through using the foreach. An IEnumerable linq statement executes when you iterate the foreach, but you emanet force C# IStructuralComparable Nasıl kullanılır it to iterate sooner using .ToList().

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 C# IStructuralComparable Kullanımı allowed to return 'sensible' data if it's able to do so or throw an exception if it kişi'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 C# IStructuralComparable nedir change things, though.

Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element C# IStructuralComparable Nasıl kullanılır in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the ışıntı and indicating input and output of the Enum?

I C# IStructuralComparable Kullanımı think if your newly implemented class just behaves the sameway birli 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 gönül inherit list or you birey implement IEnumerable. It just depends what is to be achieved.

My question is that should these classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.

Here is why it loads twice birli fewer items as the first example on average. Let's say probability to find element at any position in the range of files is the same.
