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", kakım you say, you won't be able to see how it can be avoided.
IEnumerable saf been used to represent a read-only collection of veri since the earliest versions of .Kemiksiz. The read-only collection interfaces available in .NET Core and .Kemiksiz 5 enable you to design classes that prevent the collections from being modified.
Kemiksiz 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.
List's are a very common datastructure, but creating them in this fashion involves quite a bit of syntactic noise - and it dirilik easily get even worse (e.g.
GitHub'da bizimle ortaklık strüktürn Bu hapishaneğin kaynağı GitHub'da bulunabilir; burada hatta sorunları ve çekme isteklerini oluşturup gözden geçirebilirsiniz. Henüz bir tomar vukuf için ulamada bulunan kılavuzumuzu inceleyin.
Anyway, I believe that a domain object should be read-write, because at the end of the day, a domain object describes an entity within the domain and you should be able to access and modify it.

Average(IEnumerable, Func) Computes the average of a sequence of nullable Decimal values that are obtained by invoking a transform function on each element of the input sequence.
To guarantee thread safety during enumeration, you birey lock the collection during the entire enumeration. To allow the collection to C# ReadOnlyCollectionBase Kullanımı be accessed by multiple threads for reading and writing, you must implement your own synchronization.

Descendants(IEnumerable) Returns a collection of elements C# ReadOnlyCollectionBase Kullanımı that contains the descendant elements of every element and document in the source collection.

End Sub And that's all you need to write. The class that's using your new read-only collection would be identical to the class that used my custom PhvReadOnlyList. In fact, if that's all you want, then you don't even need to create your own version of the ReadOnlyCollectionBase class -- the .
If however your intent is to prevent the calling code from observing updates from other threads you'll have to fall back to solutions already mentioned, to perform a deep or shallow copy depending on your need.
