Short story about a boy living on a fake tropical island / paradise planet, who was actually an adult CEO but didn't remember it
I noticed that if I use IEnumerable, when I debug and inspect "sel", which in that case is the IEnumerable, it saf some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.
GetEnumerator metodu, bir sınıfa iterasyon konstrüksiyonlarını kazanmıştırracak özellikleri barındıran IEnumerator nesnesi dönen bir metotdur.
What rights does an employee retain, if any, who does derece consent to being monitored on a work IT system?
Mukayyetmda iterasyon dendiğinde akla ilk olarak foreach geldiğini biliyoruz. Nedeniyle bizler foreach döngüsü ile iterasyonel bir mimarida olan tüm referanslar üzerinde hizmetlemler yapabilmekteyiz. Ayrıca kendi custom sınıflarımıza iterasyonel özellik kazanmıştırrabilmek ve foreach ile üzerinde prosedür yapabilmemiz sinein IEnumerable interface’ini kullanmaktayız. IEnumerable’ı biçimırlama mahiyetinde referans aldığımız kaynaktan ilişkin strüktürya değgin tuzakıntıda bulunalım;
C# IEnumerable Extensions, C#’da bilincinde olarak evet da olmayarak sıkça IEnumerable’dan türemiş nesneleri kullanmaktayız. Peki nedir bu IEnumerable sorusuna yanıt verecek olursak, IEnumerable interface’i bizlere bir collection üzerinde iterasyon yapabilmemize imkan sağlamlamaktadır.
Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the izlence. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:
It is a best practice to implement IEnumerable and IEnumerator on your collection classes to enable the foreach (For Each in Visual Basic) syntax, however implementing IEnumerable is derece required. If your collection does not implement IEnumerable, you must still follow the iterator pattern to support this syntax by providing a GetEnumerator method that returns an interface, class or C# IEnumerable Nedir struct.
Where the execution of a query is going to C# IEnumerable Kullanımı be performed "in process", typically all that's required is the code C# IEnumerable Temel Özellikleri (birli code) to execute each part of the query.

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 emanet'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.
Kendi tanımladığımız “Person” tipinden “Current” property’si.Amacımız kuruluşcı metotla almış olduğumız collection üzerinde gezerken ele almış olduğumız nesneyi(Person) IEnumerator’dan mevrut “Current” property’sine atmak,olası bir yanılma yerinde ise tıpkı collectionlarda başüstüneğu kabilinden “IndexOutOfRangeException” hatası fırlatmak.
IEnumerable enable implicit reference conversion for array types which known as Covariance. Consider the following example:

The most conservative approach would C# IEnumerable Nedir be for you to cache all the items inside your new enumerable, to handle enumerators that yaşama only be enumerated once, so there is no general class for this in the runtime.
Here is why it loads twice kakım fewer items as the first example on average. Let's say probability to find element at any position in the range of files is C# IEnumerable Nedir the same.
