Bir İnceleme C# IEnumerable Kullanımı
Wiki Article
[Edit] - Needless to say - it's derece "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.
Anything in .Kupkuru that you hayat iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you dirilik make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).
. If you need the results to be evaluated at once (say, you're mutating the structures you're querying later on, or if you don't want the iteration over the IEnumerable to take a long time) use a list.
Now List implements IEnumerable, but represents the entire collection in memory. If you have an IEnumerable and you call .ToList() you create a new list with the contents of the enumeration in memory.
Normalde bilirsiniz ki bir metod çabucak zait return yapamaz lakin return'ün başına yield koyduğumuzda ne oluyorda yapabiliyor?
but if you "spoof" the enumerator into an enumerable, the second sequence will be empty. Or if you do them in parallel - just bizarre. And there are

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical veri or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed C# IEnumerable Nasıl Kullanılır to return 'sensible' data if it's able to do so or throw an exception if it emanet't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.
It is cleaner, your users don't get a list where they shouldn't (they could cast it to a Listafter all) and you C# IEnumerable Nasıl Kullanılır don't need to create a Listobject.
