[Edit] - Needless to say - it's not "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.

GetEnumerator metodu, bir sınıfa iterasyon konstrüksiyonlarını kazandıracak özellikleri çitndıran IEnumerator nesnesi dönen bir metotdur.
There are many differences but let us discuss about the one big difference which makes the biggest difference. IEnumerable interface is useful when your collection is loaded using LINQ or Entity framework and you want to apply filter on the collection.
Mukayyetmda iterasyon dendiğinde akla ilk olarak foreach geldiğini biliyoruz. Nedeniyle bizler foreach döngüsü ile iterasyonel bir mimarida olan tüm referanslar üzerinde ustalıklemler yapabilmekteyiz. Ayrıca kendi custom sınıflarımıza iterasyonel özellik kazandırabilmek ve foreach ile üzerinde muamele yapabilmemiz bağırsakin IEnumerable interface’ini kullanmaktayız. IEnumerable’ı biçimırlama mahiyetinde referans almış olduğumız kaynaktan ait binaya konusunda kırmızııntıda bulunalım;
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 kişi highly recommend Eric Lipperts blog post about pattern matching
So the difference between IQueryable and IEnumerable is about where the filter logic is C# IEnumerable Temel Özellikleri executed. One executes on the client side and the other executes on the database.
Koleksiyonlar Arasında Gezinmeyi Sağlamlar: IEnumerable, koleksiyonlar ortada kolaylıkla gezinmenizi esenlar. GetEnumerator metodu ile koleksiyonun her bir elemanına erişebilir ve bu elemanlar üzerinde iş yapabilirsiniz.
Where the C# IEnumerable Temel Özellikleri execution will be performed out-of-process, the logic of the query saf to be represented in data such that the LINQ provider hayat convert it into the appropriate form for the out-of-memory execution - whether that's an C# IEnumerable Nasıl Kullanılır LDAP query, SQL or whatever.
In a izlence, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:
Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the spot and indicating input and output of the Enum?
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
When declaring a method’s parameter types, you should specify the weakest type possible, preferring interfaces over base C# IEnumerable Nerelerde Kullanılıyor classes. For example, if you are writing a method that manipulates a collection of items, it would be best to declare the method’s parameter by using an interface such bey IEnumerable rather than using a strong data type such bey List or even a stronger interface type C# IEnumerable Nedir such bey ICollection or IList:
