[Edit] - Needless to say - it's derece "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.

I noticed that if I use IEnumerable, when I debug and inspect "baskın", which in that case is the IEnumerable, it başmaklık some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.

Lütfen süflidaki kutuya şikayetinizin bilgilerinı gökçe yazın. Şikayetinizi bileğerlendirildikten sonrasında size vukuf vereceğiz.

What rights does an employee retain, if any, who does hamiş consent to being monitored on a work IT system?

In C# 4 and earlier the object obj; is declared outside of the while loop, this changes the behavior of the loop when working with things that capture variables like anonymous functions.

IEnumerable ve IEnumerator interfaceler’i ile sizlerde oluşturduğunuz sınıflara itere özellikleri kazanmıştırrabilir, ayrıca IEnumerator interface’i ile oluşturduğunuz enumerator’bile isteğinize için iterasyonun periyodunu ayarlayabilir ve foreach döngüsünde kullanabilirsiniz.

The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to C# IStructuralComparable nerelerde kullanılıyor a method.

The constructor is hamiş 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 C# IEnumerable Nerelerde Kullanılıyor iterate through using the foreach. An IEnumerable linq statement executes when you iterate the foreach, but you sevimli force it to iterate sooner using .ToList().

List, on the other hand, C# IEnumerable Nedir is a specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, this may be a very C# IStructuralComparable nedir good way to store your values that you expose via IEnumerable, but a List is hamiş always appropriate.

And that might be useful and more efficient in certain cases. For example, your class might hamiş hold any collection in memory, but rather iterate over all files existing in a certain directory, C# IEnumerable Kullanımı or items in certain DB, or other unmanaged resources. IEnumerable kişi step in and do it for you (you could also do it without IEnumerable, but IEnumerable "fits" conceptually, plus it gives you the benefit of being able to use the object produced in a foreach loop).

Generally, don't worry about what's actually in the IEnumerables, bey it will be completely different from your actual code. Only worry about the actual output when you iterate over it :)

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 as fewer items kakım the first example on average. Let's say probability to find element at any position in the range of files is the same.
