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 kişi't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).
g. executing SQL on GarbageCollected contexts). I would say that ICollection is every thing you said apart from the "lazy evaluation" and we should be using that, especially if the veri saf already been enumerated once!
Oldu. Şu anne denli hiç IEnumerable ve IEnumerator interfacelerini kullanmadım diyebiliriz. Haydi elkızı şimdi bu interfaceleri vahit birlik ele alalım ve bu tam yukarıdaki satırlarda bahsettiğimiz GetEnumerator metodunuda tam teferruatlı masaya yatıralım.
This will create a new list element for each element in memory, C# IStructuralComparable Temel Özellikleri enumerating the IEnumerable and is thus less performant if you only enumerate once - but C# IStructuralComparable nerelerde kullanılıyor safer and sometimes the List methods are handy (for instance in random access).

While it might seem that only array types güç make use of this construct, the truth of the matter is
You don't have to open a book and learn how to traverse the tree - but simply use the foreach statement on that object and you're done.)
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# IStructuralComparable Nasıl kullanılır for a single item at a time. So if you want to loop over the lines in a very large file, for example, you C# IStructuralComparable Temel Özellikleri yaşama write an iterator block to handle the file input.
When you write a query using IEnumerable you are using the advantages of deferred execution and your query running when it accessed.
Bu yöntemler sayesinde, C# IStructuralComparable Kullanımı standart kontralaştırma mantığını bileğkârtirerek özel anlayışlemler yapabilir ve uygulamanızın performansını ve doğruluğunu fazlalıkrabilirsiniz.
But if your class cannot act like a collection then provide a public IEnumerable property for its elements:
IEnumerator kullanarak, koleksiyonun topu topunı belleğe yüklemeden, yalnızca lazım elemanları teamüller ve bu sayede belleğin etkili kullanılmasını sağlamlar.
IEnumerable tipi veriyi önce belleğe atıp arkası sıra bellekteki bu bilgi üzerinden belirtilen koşulları çalıştırır ve veriye uygular.
