IEnumerable bütün verileri aldatmaıp memory de sara, sorgulama maslahatlemlerini memory üzerinden yaparken IQueryable ise şartlara rabıtalı query oluşturarak vasıtasız veritabanı üzerinden sorgulama aksiyonlemi yapar.
What this code is saying is that if userId was specified, then add a filter on the veri so that only items where the userId matches that variable will be included. That same thing is done for email and lastFourdigits.
So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.

Sonunda burada ortaya çısoy sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isimli metot implement ettirilmektedir. IEnumerator ise dayalı sınıfa iterasyon davranışleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesuliyetli olacaktır.
Why do many philosophers consider a past-eternal universe to be self-explanatory but not a universe that began with no cause?

IEnumerable describes behavior, while List is an implementation of that behavior. When C# IEnumerable Nasıl Kullanılır you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right C# IEnumerable Nerelerde Kullanılıyor away.

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, C# IEnumerable Nasıl Kullanılır which would support Reset and guarantee that multiple passes will either return identical data or throw C# IEnumerable Kullanımı 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.
Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the C# IEnumerable Temel Özellikleri 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?
Bir sonraki elementin varlığını sınayan MoveNext ve makbul elementi veren GetCurrent metodlarına sahiptir.
In simple words other major difference is that IEnumerable execute select query on server side, load veri in-memory on client side and then filter data while IQueryable execute select query on server side with all filters.
