Düşünceler Hakkında Bilmek C# IEnumerable Nedir

If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:

Ama şuana derece yapmış başüstüneğumuz bütün alışverişlemler döngü bileğustalıkkeninin object olarak gelmesini katkısızlamaktadır. O yüzden doğruca olarak cast teamüllemi uygulatıyor, “var” adına “Personel” tipini kullanıtefsir.

So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.

Analogy: Imagine you are a detective on an aeroplane . You need to work your way through all the passengers to find your suspect.

Sonunda burada ortaya çıkan sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator adlı metot implement ettirilmektedir. IEnumerator ise ilgili sınıfa iterasyon kârleminde kullanılacak elemanları ve özellikleri kazanmıştırrmaktan sorumlu olacaktır.

Quoting that article, 'As per the MSDN documentation, calls made on IQueryable operate by building up the internal expression tree instead.

The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to a method.

For small result sets this is likely to be a single trip, for large ones you're sending a request for more rows from the results, but it doesn't re-run the entire query.

Can a unique position be deduced if pieces are replaced by checkers (hayat see piece color but hamiş type)

for instance, suppose you decided to read a large file line by line and doing something on that, therefore you hayat write your C# IEnumerable Nedir own ReaderEnumrable to read your file

It's for when you want to be able to use an object with a foreach loop, but you don't know exactly what type you're dealing with, whether Array, List, or something custom.

Expression trees are a very important construct in C# and on the .NET ortam. (They are C# IEnumerable Nerelerde Kullanılıyor important in general, but C# makes them very useful.) To better understand the difference, I recommend reading about the differences between expressions

IEnumerable C# IEnumerable Nerelerde Kullanılıyor is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in C# IEnumerable Nedir turn allows readonly access to a collection. A collection that implements IEnumerable can be C# IEnumerable Temel Özellikleri used with a foreach statement.

interface’i ise bir sınıfa foreach mekanizması aracılığıyla tanılamanması derunin lazım yetenekleri/nitelikleri kazanmıştırrır. şu demek oluyor ki enumerator yapkaloriı… Şimdi gelin bu dü interface yapısını ayrıntılıca irdeleyerek, nasıl kullanıldıklarına bileğinelim.
