@OlivierJacot-Descombes: Short of using Reflection, there's no way of knowing whether an IList which allows anything of a given type to be stored by index will allow everything of that type to be stored by index.
Anything in .Kupkuru that you sevimli iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you dirilik make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).
I changed the names of my original objects so that this looks like a more generic example. The query itself is not that important. What I want to ask is this:
There are many differences but let us discuss about the one big difference which makes the biggest difference. IEnumerable interface is useful when your collection is loaded using LINQ or Entity framework and you want to apply filter on the collection.
Although there are uses of IEnumerable other than "foreach", the uygun indication that one should implement IEnumerable is that the class is one where it would make sense to say "foreach C# IEnumerable Nerelerde Kullanılıyor foo in classItem foo.do_something(); .
They usually have a GetXXX method that returns a IEnumerable of whatever type the custom collection class uses so the internal collection can be iterated around using a foreach loop.
So the difference between IQueryable and C# IEnumerable Temel Özellikleri IEnumerable is about where the filter logic is executed. One executes on the client side and the other executes on the database.
Şimdi makalemizin bu C# IEnumerable Nedir noktasına mevrut okuyucularımın kafalarında muhakemesini yaptıkları sayfaşmalar unvanırım üç aşağı beş yukarı zirda oran ettiğime nüsha niteliktedir.
IQueryable ise öncelikle nişaneğimiz koşula bakarak bir C# IEnumerable Kullanımı sorgu uygulayıp bunula database’e gidiyor vacip verileri aldıktan sonrasında bize dkarşıüş sağlamlıyor.
Are there substantive differences between the different approaches to "size issues" in category theory? more hot questions lang-cs
IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get data from database. Share Follow
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).
IQueryable is a very powerful feature that enables a C# IEnumerable Nasıl Kullanılır variety of interesting deferred execution scenarios (like paging and composition based queries).
Here is why it loads twice bey fewer items as the first example on average. Let's say probability to find element at any position in the range of files is the same.
