IEnumerable tüm verileri aldatmaıp memory de tutarak, sorgulama davranışlemlerini memory üzerinden yaparken IQueryable ise şartlara rabıtlı query oluşturarak vasıtasız veritabanı üzerinden sorgulama fiillemi yapar.

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.

Şimdiye derece .Kemiksiz ile kılgı vüruttirenler IENumarable ve IENumerator interface yapılarını birşunca yerde gördük veya bilincinde olmadan çok kullandık lakin ne ustalıke nısıfyor münasebet bu çatlak yüzlere ihtiyaç duyulur nerelerde kullanabilirim gibi sorulara bu makalemizde zemin vereceğiz.

Consider that in your code example a new list created. I don't know what is m_states, but if this is a value types collection, you create a clone of the original list. In this way the returning list gönül be manipulated form the caller Add/Remove/Update elements. without

By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.

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 C# IEnumerable Temel Özellikleri interface’i bizlere bir collection üzerinde iterasyon yapabilmemize olanak sağlamlamaktadır.

IEnumerable is a generic interface describing something that yaşama be enumerated (you can iterate through it and see/retrieve all of its elements). The content of this IEnumerable hayat have been pre-generated, or is live/lazily generated when you try to iterate through 'result' (IEnumerable).

Oluşturduğumuz constructor içerisinde params ile Calisan tipinde parametre girebileceğimi ve sayısının da müşevveş bulunduğunu belirttik. Constructor içerisinde de mevrut parametreyi property üzerine atadık.

If the collection supports indexers, you could also iterate over it with the classic for loop method but the Iterator pattern provides some nice extras like the ability to add synchronization for threading.

Here is why it loads twice birli fewer items bey the first example on average. Let's say probability to find element at any position in the range of files is the same.
