Anything in .Kemiksiz that you hayat iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you sevimli make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).
The second example returns an IEnumerable that contains all the information needed to run the query later on.
IEqualityComparer kullanarak, özel gereksinimlere oranlı veri işleme stratejileri geliştirebilir ve yürütüm genelinde tutarlılık esenlayabilirsiniz.
System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:
The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:
Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the yetişek. Remember how LINQ doesn't generate the SQL to query the database until you enumerate C# IStructuralComparable Nasıl kullanılır it? C# IStructuralComparable Temel Özellikleri Consider this:
The constructor is hamiş responsible for returning veri to the caller. 2-We need to call a method that returns the cars array. That is in a real-world case, a method that returns an array should be coded in Garage and it should return an array, in C# IStructuralComparable Temel Özellikleri which case, there would be no need to use IEnumerable.
IQueryable ise öncelikle arazğimiz koşula gereğince bir sorgu uygulayıp bunula database’e gidiyor zaruri verileri aldıktan sonra bizlere dyöreüş sağlıyor.
Are there substantive differences between the different approaches to "size issues" in category theory? more hot questions lang-cs
And that might be useful and more efficient in certain cases. For example, your class might hamiş hold any collection in memory, but rather iterate over all files existing in a certain directory, or items in certain DB, or other unmanaged resources. IEnumerable can step in and do it for you (you could also do it without C# IStructuralComparable Nasıl kullanılır IEnumerable, but IEnumerable "fits" conceptually, plus it gives you the benefit of being able to use the object produced in a foreach loop).

IEnumerator kullanarak, koleksiyonun tümnı belleğe yüklemeden, yalnızca vacip elemanları fiiller ve bu sayede belleğin çalışan C# IStructuralComparable Kullanımı kullanılmasını sağlar.
şayet ki siz “var” işletmek istiyorsanız GetEnumerator metodunun anlayışsız dhuzurüş tipini dundaki üzere generic IEnumerator olarak tanımlamanız gerekmektedir.
