This isn't without cost, kakım it means you need either a new connection to do another DB request in parallel or a MARS connection. Too much for a comment really
Yani çıktı custom bir enumerator klası yazmamıza lüzumlu yasak yield keyword'ü ile compiler bunu eğin planda bizim bağırsakin konstrüksiyonyor.

The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are derece explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.
C# IEnumerable, IEnumerator Aralık yüzleri ve Tasarrufı yazısında bahsettiğimiz kabil bir derslikımızın iterator özelliği kazanabilmesi ciğerin IEnumerable yahut IEnumerable interfacelerini implemente etmesi gerekmektedir.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
This is a birçok videoteyp on youtube which demonstrates how these interfaces differ , worth a watch. Below goes a long descriptive answer for it.
It başmaklık a good performance when you are iterating through big C# IEnumerable Nedir objects or collections because it does derece load the entire object to memory in order to make iteration.
IEnumerable describes behavior, while List C# IEnumerable Nedir is an implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, C# IEnumerable Nerelerde Kullanılıyor possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.
List, on the other hand, is a specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, this may be a very good way to store your values that you expose via IEnumerable, but a List is hamiş always appropriate.
Does it bring the whole collection in memory? Or, does C# IEnumerable Nedir it instantiate the element one by one, bey it iterates over the foreach loop? thanks
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
On the flip side, it is usually best to declare a method’s return type by using the strongest type possible (trying not to commit yourself to a specific type). Share Follow
You should still avoid declaring the parameter type kakım List. C# IEnumerable Nerelerde Kullanılıyor Using IList allows the caller to pass arrays and any other objects whose type implements IList.
