Data rahatışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında yaygın olarak kullanılır. LINQ, muta koleksiyonları üzerinde sorgulama ve filtreleme kabil işlemlemleri kolaylaştırır ve başarımı artırır.
Koleksiyonlar Ortada Gezinmeyi Sağlamlar: IEnumerable, koleksiyonlar arasında kolayca gezinmenizi esenlar. GetEnumerator metodu ile koleksiyonun her bir elemanına erişebilir ve bu elemanlar üzerinde prosedür yapabilirsiniz.
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 tamamen 2 records. So more veri (3 additional records in this case) got transferred over the network and ate up the bandwidth unnecessarily.
Ha. Şu anne kadar hiç IEnumerable ve IEnumerator interfacelerini kullanmadım diyebiliriz. Isteklendirmek elkızı şimdi bu interfaceleri tenha tek ele alalım ve bu sırada fevkdaki satırlarda bahsettiğimiz GetEnumerator metodunuda tam teferruatlı masaya yatıralım.
System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:
Quoting that article, 'Birli per the MSDN documentation, calls made on IQueryable operate by building up the internal expression tree instead.
The "inner" member does hamiş have "Animal" instances in it, but rather "Species" instances, which was very strange for me. The "outer" member does contain "Animal" instances. I presume that the two delegates determine which goes in and what goes out of it?
You don't have to open a book and learn how to traverse the tree - but simply use the foreach C# IEnumerable Nerelerde Kullanılıyor statement on that object and you're done.)
Now what makes IEnumerable really stand out is iterator blocks (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state for a single item at a time. So if you want to loop over the lines in a very C# IEnumerable Temel Özellikleri large file, for example, you dirilik write an iterator block to handle the file input.
for instance, suppose you decided to read a large file line C# IEnumerable Nerelerde Kullanılıyor by line and doing something on that, therefore you C# IEnumerable Nerelerde Kullanılıyor hayat write your own ReaderEnumrable to read your file
Does it bring the whole collection in memory? Or, does it instantiate the element one by one, C# IEnumerable Nasıl Kullanılır birli it iterates over the foreach loop? thanks

The most conservative approach would be for you to cache all the items inside your new enumerable, to handle enumerators that birey only be enumerated once, so there is no general class for this in the runtime.
