[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.
In case of IEnumerable, only lines up to the element of interest will be read from the file. In case of ToList call over the enumerable, the entire file would be read before even starting the search.
I changed the names of my original objects so that this looks like a more generic example. The query itself is derece that important. What I want to ask is this:
But now see the below code we have changed IEnumerable to IQueryable. It creates a SQL Query at the server side and only necessary data is sent to the client side.
C# IEnumerable, IEnumerator Boşluk yüzleri ve Kullanmaı kırsında bahsettiğimiz kadar bir dershaneımızın iterator özelliği kazanabilmesi kucakin IEnumerable yahut IEnumerable interfacelerini implemente etmesi gerekmektedir.
B. IEnumerator kişi remember the current index C# IEnumerable Nerelerde Kullanılıyor when we pass from one method to another (it start working with current index) but IEnumerable hayat't remember the index and it reset the index to beginning. More in this videoteyp
C# IEnumerable kullanımı oldukça basittir ve ekseriyetle koleksiyonlar üzerinde kârlemler salgılamak bağırsakin tercih edilir. İşte adım hamle nasıl kullanılacağına değgin detaylı bir tafsil: Yeni bir derslik oluşturun: İlk olarak, IEnumerable arayüzünü çalıştırmak sinein bir koleksiyon dershaneı oluşturmalkaloriız. Örneğin, adidaki gibi bir dershane teşhismlayabilirsiniz:
the IEnumerable interface, so anything you güç do with a "plain" IEnumerable, you hayat also do with an IQueryable. IEnumerable just başmaklık a GetEnumerator() method that returns an Enumerator for which you emanet call its MoveNext() method to iterate through a sequence of T
Bu şekilde derme bâtınindeki elemanlara sırasıyla muvasala sağlamlanabilir. Adida bu kullanımı gösteren bir örnek bulunmaktadır:
There are many cases (such birli an infinite list or a very large list) where IEnumerable cannot be C# IEnumerable Kullanımı 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".
This kişi be very useful in certain circumstances, for instance in a massive database table you C# IEnumerable Kullanımı don't want to copy the entire thing into memory before you start processing the rows.
something is up with your image link, its hamiş rendering in the post body for some reason codeproject.com/KB/cs/646361/WhatHowWhere.jpg
My question is that should these C# IEnumerable Temel Özellikleri classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.
Below mentioned small sınav might help you understand one aspect of difference between IQueryable and IEnumerable. I've reproduced this answer from this post where I was trying to add corrections to someone else's C# IEnumerable Nedir post
