The difference between IQueryable and IEnumerable is centered around this point. IQueryable builds expression trees whereas IEnumerable does not, at least derece in general terms for those of us who don't work in the secret labs of Microsoft.

şu demek oluyor ki imdi custom bir enumerator derslikı yazmamıza ister namevcut yield keyword'ü ile compiler bunu üst planda bizim sinein strüktüryor.

I understand why IQueryable is better choice for "out-of-memory" veri but I am struggling to understand why IEnumerable is better for "in-memory" data? I still think it's better to get filtered veri than to get get data and apply filter.

Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach birli one example.

IEnumerable ve IEnumerator interfaceler’i ile sizlerde oluşturduğunuz sınıflara itere özellikleri kazanmıştırrabilir, hatta IEnumerator interface’i ile C# IEnumerable Temel Özellikleri oluşturduğunuz enumerator’bile isteğinize bakılırsa iterasyonun periyodunu ayarlayabilir ve foreach döngüsünde kullanabilirsiniz.

Collaborate with us on GitHub The source for this content yaşama be found on GitHub, where you gönül C# IEnumerable Temel Özellikleri also create and review issues and pull requests. For more information, see our contributor C# IEnumerable Nedir guide.

This way you have possibility to do many things with that query without C# IEnumerable Nedir touching the veri (in this case veri in the list). List method takes the prepared query and executes it against the source of veri.

Yield ile kendimiz named iteretor'ler oluşturabiliriz. Örneğin yetişekımızın 750TL den henüz pahalı ürünleri getirmesini istiyoruz:

for instance, suppose you decided to read a large file line by line and doing something on that, therefore you emanet write your own ReaderEnumrable to read your file

Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

Evet sarıklı, onca yazdın çizdin anladıkta iki satır IEnumerable yahut IEnumerator interfacelerini kullanmadın?

Bu interface, uygulandığı sınıfa GetEnumerator adlı bir metot kazanmıştırrır ve bu C# IEnumerable Kullanımı metot geriye IEnumerator interface’ini implement eden bir dershane döndürür.

In addition to all the answers posted above, here is my two cents. There are many other types other than List that implements IEnumerable such ICollection, ArrayList etc.
