So when you have to simply iterate through the in-memory collection, use IEnumerable, if you need to do any manipulation with the collection like Dataset and other data sources, use IQueryable

. 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.

A. We iterate the list in different way, foreach birey be used for IEnumerable and while loop for IEnumerator.

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

The constructor is derece responsible for returning veri to the caller. 2-We need to call a method that returns the cars array. That is in a C# IEnumerable Nedir real-world case, a method that returns an array should be coded in Garage and it should return an array, in which case, there would be no need to use IEnumerable.

Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on an IC?

List, on the other hand, is a specific implementation of IEnumerable that stores the objects in a specific, known C# IEnumerable Nerelerde Kullanılıyor manner.

Oh sure, you gönül use it to create your own C# IEnumerable Nerelerde Kullanılıyor custom collection types. But for everyday stuff, it probably isn't birli useful as the collections derived from it.

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).

Unfortunately IEnumarable seems to be blindly used birli the lowest interface which now causes problems with asynchronous data manipulation (e.

IEnumerable tipi veriyi önce belleğe atıp ardından bellekteki bu bilgi üzerinden tamlanan koşulları çalıştırır ve veriye uygular.
