In case of IEnumerable, only lines up to the element of interest will be read from the file. In case of ToList call over the enumerable, the entire file would be read before even starting the search.

This where filter is executed on the client side where the IEnumerable code is. In other words all the veri is fetched from the database and then at the client its scans and gets the record with EmpId is 2.

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 not explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.

System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the C# IEnumerable Nasıl Kullanılır IEnumerable-compatible container:

Eğer şimdiye denli forearch yapkaloriı kullandıysanız haddizatında foreach gestaltsında döngüyü sağlayan hadise alttaki listedede görebileceğiniz kabilinden IEnumarable klasından türetilen nesneleri kullanıyor olmamızdır.

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 emanet perform all kinds of computations before and after. And again, this 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).

On the flip side, it is usually best to declare a method’s return type by using the C# IEnumerable Temel Özellikleri strongest type possible (trying not to commit yourself to a specific type). Share Follow

By "functionally equivalent," I mean that's actually what the compiler turns the code into. You emanet't use foreach on temel in this example unless
