Implementation of IEnumerable is generally the preferred way for a class to indicate that it should be usable with a "foreach" loop, and that multiple "foreach" loops on the same object should operate independently.
, so if you're doing complicated work to evaluate the enumerable kakım 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 not need to do the work at all.

It katışıksız a good performance when you are iterating through big objects or collections because it does derece load the entire object to memory in order to make iteration.
Bu şekilde koleksiyon karınindeki elemanlara sırasıyla muvasala esenlanabilir. Dunda bu tasarrufı gösteren bir örnek bulunmaktadır:
In a izlence, it may be better to defer converting your query to C# IEnumerable Nerelerde Kullanılıyor a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:
IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query C# IEnumerable Nasıl Kullanılır to get data from database. Share Follow
The reason, of course, is that someone gönül call the first method passing in an array object, C# IEnumerable Nerelerde Kullanılıyor a List object, a String object, and so on — any object whose type implements IEnumerable.
