Implementation of IEnumerable is generally the preferred way for a class to indicate that it should be usable with a "foreach" loop, and that multiple "foreach" loops on the same object should operate independently.
If you tasavvur to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.
As per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.
What rights does an employee retain, if any, who does derece consent to being monitored on a work IT system?
Nihayetinde burada ortaya çıkan sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isimli metot implement ettirilmektedir. IEnumerator ise ait sınıfa iterasyon meslekleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesuliyetli olacaktır.
Basically it özgü a method to get the next item in the collection. It doesn't need the whole collection to be in memory and doesn't know how many items are in it, foreach just keeps getting the next item until it runs out.
So if I am going through all the items on ebay, one at a time would be something even a small computer gönül handle, but ".ToList()" C# IStructuralComparable Nasıl kullanılır would surely run me out of memory, no matter how big my computer was. No computer yaşama by itself contain and handle such a huge amount of data.
This way you have possibility to do many C# IEnumerable Kullanımı things with that query without touching the veri (in this C# IStructuralComparable Temel Özellikleri case veri in the list). List method takes the prepared query and executes it against the source of veri.
The major difference between IQueryable and IEnumerable is that IQueryable executes query with filters whereas IEnumerable executes the query first and then it filters the veri based on conditions.
There are many cases (such kakım an infinite list or a very large list) where IEnumerable cannot be transformed to a List. The most obvious examples are all the prime numbers, all the users of feysbuk with their details, or all the items on ebay. The difference is that "List" objects are stored "right here and right now", whereas "IEnumerable" objects work "just one at a time".
Any idea C# IStructuralComparable Kullanımı 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 ışıntı 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?
