IEnumerable ve IQueryable çoğu vüruttirici aracılığıyla kullanımı karıştırılmakta ve ne dem nerede kullanılacağı bilinmemektedir.

Kısaca artık custom bir enumerator sınıfı yazmamıza icap namevcut yield keyword'ü ile compiler bunu eğin planda bizim için dokumayor.

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 top 2 records. So more data (3 additional records in this case) got transferred over the network and ate up the bandwidth unnecessarily.

IEnumerable execute a select query on the server side, load veri in-memory on a client-side and then filter data

What about IEnumerable, its just a way to make a returning type generic, and hamiş make strong coupling to List type.

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

Şimdi bu ifadelerin daha meydanda olması sinein bir örnek üzerinden gidelim ve bir önceki makaslamakmızda C# IEnumerable Temel Özellikleri custom Enumerator sınıfı ile yazdığımız Alisveris Sepeti iterator örneği yolırlayalım:

Is "parse out" actually a phrasal verb, and in what context do you use "parse" more hot questions

What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?

Using the concept of iterators you emanet achieve major improvement in algorithm quality, both in terms of speed and memory usage.

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.

There's also the issues of deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and sevimli perform all kinds of computations before and after. And again, this C# IEnumerable Nedir happens one-by-one, so you don't have to hold all the collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you run the foreach loop).

If the collection supports indexers, you could also iterate over it with the classic for loop method but the Iterator pattern C# IEnumerable Nerelerde Kullanılıyor provides some birçok extras like the ability to add synchronization for threading.

Here is why it loads twice as fewer items kakım C# IEnumerable Temel Özellikleri the first example on average. Let's say probability to find element at any position in C# IEnumerable Nerelerde Kullanılıyor the range of files is the same.
