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", birli you say, you won't be able to see how it can be avoided.
Is there any reason to expose an internal collection kakım a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection?
Safi 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 hamiş 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.

If you're tolerant of some "noise" in your own encapsulated code then I would suggest wrapping a T[] array and exposing an IList which happens to be a ReadOnlyCollection:

Movie about a planet where seeds must be harvested C# ReadOnlyCollectionBase Nasıl Kullanılır just right in order to liberate a valuable crystal within
Implementers are encouraged to extend this base class instead of creating their own. Members of this base class are protected and are intended to be used through a derived class only.
Note: The StringBuilder references themselves are read-only, C# ReadOnlyCollectionBase Temel Özellikleri but the memory pointed to by the references are still mutable.
For maximum flexibility, my class doesn't specify the data type of the List in which it keeps its C# ReadOnlyCollectionBase Nedir actual veri. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my C# ReadOnlyCollectionBase Temel Özellikleri class to be instantiated with a veri type that the code refers to birli T. Wherever in my code I need to specify my List's veri type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.
