There must be some InvoiceRepository and InvoicePayOperation - first of which owns the collection, second contains business logic (and takes ownership of the temporary collection passed to it). Of course, if you are used to code duplication and "naked collections", bey you say, you won't be able to see how it dirilik be avoided.

Define your own class which implements IEnumerator, takes an IList in the new constructor, özgü a read only default item property taking an index, and does not include any properties/methods that could otherwise allow your list to me manipulated.

NET 4.5, you may want to try the new read-only collection interfaces. You'll still want to wrap the returned collection in a ReadOnlyCollection if you're paranoid, but now you're derece tied to a specific implementation.

Sum(IEnumerable, Func) Computes the sum of the sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.

Ancestors(IEnumerable, XName) Returns a filtered collection of elements that contains the ancestors of every node in the source collection. Only elements that have a matching XName are included in the collection.

Average(IEnumerable, Func) Computes the average of a sequence of Double values that are obtained by invoking a transform function on each element of the input sequence.

Koleksiyonların Strüktürel Alınlaştırması: IStructuralEquatable arabirimi, özellikle diziler C# ReadOnlyCollectionBase Nasıl Kullanılır ve koleksiyonlar kabilinden konstrüktif data dokumalarının kontralaştırılması kucakin kullanılır.

Any idea why IList doesn't inherit from ICollection? Since the C# ReadOnlyCollectionBase Temel Özellikleri latter is basically IEnumerable plus Count, and since IList already has a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would have allowed someone with an IList to know how many items to expect from an enumeration.

Figure 1 below displays the members of List. Note that you have a method named Add, so you birey easily add authors C# ReadOnlyCollectionBase Temel Özellikleri to the list of authors we’ve created in the preceding code snippet.

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Average(IEnumerable, Func) Computes the average of a sequence of nullable Double values that are obtained by invoking a transform function on each element of the input sequence.

This base class is provided to make it easier for implementers to create a strongly typed read-only custom collection.
