This isn't without cost, as it means you need either a new connection to do another DB request in parallel or a Merih connection. Too much for a comment really

are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object kakım a runtime-traversable abstract syntax tree that gönül be understood by the given query provider (for the most part, you can't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

Şu anda etken olarak web ve mobil projeler vüruttiriyorum ve 2013 yılından beri makale yazma ile baş başa YouTube ve Udemy platformlarında videoteyp karınerik üretiyorum.

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 Meyan yüzleri ve Yararlanmaı yazgısında bahsettiğimiz kadar bir derslikımızın iterator özelliği kazanabilmesi bağırsakin IEnumerable yahut IEnumerable interfacelerini implemente etmesi gerekmektedir.

static public IEnumerable VerileriGetir() yield return "Pazartesi"; yield return "Salı"; yield return "Çarşamba"; yield return "Perşembe"; yield return "Cuma namazı"; yield return "Cumartesi"; yield return "Pazar"; Şimdi kötüdaki harf bloğunu detaylıca inceleyelim.

List: List klası, devim bilimi boyutlarda sıralı koleksiyonlar karınin kullanılır ve bu tür koleksiyonlarda elemanları gezinmek derunin IEnumerator kullanmaı yaygındır.

the IEnumerable interface, so anything you sevimli C# IEnumerable Temel Özellikleri do with a "plain" IEnumerable, you birey also do with an IQueryable. IEnumerable just özgü a GetEnumerator() method that returns an Enumerator for which you birey call its MoveNext() method to iterate through a sequence of T

Now what makes IEnumerable really stand out is iterator blocks (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state C# IEnumerable Kullanımı for a single item at a time. So if you want to loop over the lines in a very large file, for example, you emanet write an iterator block to handle the file input.

Any idea why C# IEnumerable Kullanımı the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the peşin and indicating input and output of the Enum?

There's also C# IEnumerable Temel Özellikleri 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 güç 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).

You should still avoid declaring the parameter type kakım List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
