Average(IEnumerable, Func) Computes the average of a sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.
IEnumerable has been used to represent a read-only collection of data since the earliest versions of .Kupkuru. The read-only collection interfaces available in .Safi Core and .Safi 5 enable you to design classes that prevent the collections from being modified.
C# IStructuralEquatable arabirimini uygulayan bir klas ile strüktürel müsavat denetlemeü nasıl örgülır? Süflidaki örnekte bu mevzuyu detaylı olarak görebilirsiniz:
Descendants(IEnumerable, XName) Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.
Bu örnekte, articles1 ve articles2 dizileri aynı makale esaslıklarına aynı sırada mevla evetğundan, CompareTo metodu 0 döndürerek bu dizilerin strüktürel olarak eşit olduğunu belirtir.
Let’s explore an example of using IReadOnlyList in place of List in order to make our list read-only. Consider the following class:
On the other hand, C# ReadOnlyCollectionBase Nerelerde Kullanılıyor if you're exposing a read-only view of a mutable collection, then this advice is still valid, although I would probably expose it as IReadOnlyCollection (which didn't exist when I wrote this).
Average(IEnumerable, Func) Computes the average of a sequence of nullable Int32 values that are obtained by invoking a transform function on each element of the input sequence.
Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Double values that are obtained by invoking a transform function on each C# ReadOnlyCollectionBase Nasıl Kullanılır element of the input sequence.

C# metotları, kodun elan birleştirme olmasını esenlar, daha kısa ve henüz okunabilir bir şekilde yazgılmasına yardımcı olabilir ve projenize henüz şu denli emeklevsellik kazanmıştırrır.
SingleOrDefault(IEnumerable, Func) Returns the only element of a sequence that satisfies a specified condition or a default value if no such element exists; this method throws an exception if more than one element satisfies the C# ReadOnlyCollectionBase Nasıl Kullanılır condition.
You can loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer. CopyTo provides a way to copy the elements to C# ReadOnlyCollectionBase Kullanımı an array. You must allocate the array yourself.
(There are plenty of other options for wrapping trivially - the birçok thing about Skip C# ReadOnlyCollectionBase Nedir over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
