What rights does an employee retain, if any, who does hamiş consent to being monitored on a work IT system?
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 veri (3 additional records in this case) got transferred over the network and ate up the bandwidth unnecessarily.
Evet. Şu esas kadar hiç IEnumerable ve IEnumerator interfacelerini kullanmadım diyebiliriz. Isteklendirmek gelin şimdi bu interfaceleri bir hareketsiz ele alalım ve bu tam yukarıdaki satırlarda bahsettiğimiz GetEnumerator metodunuda tam teferruatlı masaya yatıralım.
Nihayetinde burada ortaya çıdem sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator adlı metot implement ettirilmektedir. IEnumerator ise müteallik sınıfa iterasyon meslekleminde kullanılacak elemanları ve özellikleri kazanmıştırrmaktan mesul olacaktır.
So if you working with only in-memory veri collection IEnumerable is a good choice but if you want to query data collection which is C# IEnumerable Nasıl Kullanılır connected with database `IQueryable is a better choice birli it reduces network traffic and uses the power of SQL language.

IEnumerable describes behavior, while List C# IStructuralComparable nedir is an implementation of that behavior. When you use IEnumerable, you give the compiler a C# IStructuralComparable nerelerde kullanılıyor chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results C# IStructuralComparable Kullanımı right away.
Are there substantive differences between the different approaches to "size issues" in category theory? more hot questions lang-cs
IEnumerable ve IQueryable aradındaki farkı anlatmadan önce kısaca bu dü interface sınıfını teşhisyalım.
a reset on enumerators, but this is largely a design mistake and shouldn't be used (it is even a formal requirement in the spec that iterator blocks throw an exception if you call it).
If the collection supports indexers, you could also iterate over it with the classic for loop method but the Iterator pattern provides some nice extras like the ability to add synchronization for threading.
