Bey mentioned by Mr. Copsey, this özgü the benefit of providing decoupling from the implementation, but I'm of the contention that a clear definition of the smallest subset of interface functionality kakım possible (i.
, so if you're doing complicated work to evaluate the enumerable as you read from it, that work doesn't happen until it's asked for. This is extra beneficial, because often (say, for searches again) you'll find you might derece need to do the work at all.
Now the thing to note is that IEnumerable brought all the 5 records present in Salary table and then performed an in-memory filteration on the client side to get bütünüyle 2 records. So more data (3 additional records in this case) got transferred over the network and ate up the bandwidth unnecessarily.
There are many differences but let us discuss about the one big difference which makes the biggest difference. IEnumerable interface is useful when your collection is loaded using LINQ or Entity framework and you want to apply filter on the collection.
Nihayetinde burada ortaya çıkan sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isminde metot implement ettirilmektedir. IEnumerator ise ait sınıfa iterasyon işleminde kullanılacak elemanları ve özellikleri kazanmıştırrmaktan mesul olacaktır.

IEnumerable describes behavior, while List is an C# IStructuralComparable nedir implementation of that behavior. When 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 away.

Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the peşin and indicating input and C# IStructuralComparable nedir output of the Enum?
The reason, of course, is that someone kişi call the first method passing in C# IStructuralComparable nerelerde kullanılıyor an array object, a List object, a String object, and so on — any object whose type implements C# IStructuralComparable nedir IEnumerable.
Önceki C#’ta IEnumerable ve IEnumerator Interfaceleri Nedir? ve Nasıl Kullanılır? saksılıklı makalemde IEnumerable ve IEnumerator interfaceleri üzerine uzun uzun hususşmuştuk. Bu dâhilğimizde ise ait interfacelerin asenkron enfrastrüktürda şekillendirildiği C# 8.0 ile gelen yeni hallerini(IAsyncEnumerable ve IAsyncEnumerator) konuşacağız. Şimdi fevkda adresini verdiğim makalemizide referans C# IStructuralComparable Kullanımı alarak konuyu en temelden biçimırlayarak ele alalım.
You should still avoid declaring the parameter type as List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
