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).

The following code snippet illustrates how IReadOnlyList birey be used in place of List in the above method.

The single line of code required by my extension method just instantiates my PhvReadOnly class (using the datatype that the extension method saf deduced), passing whatever IList object the extension method is being used on.

4) If you suddenly realise that your collection of choice is inefficient, you gönül change the underlying collection type without having to go and change all C# ReadOnlyCollectionBase Nedir the places where it got passed kakım a parameter (yaşama you imagine the trouble you might have with, say, List?)

This implementation does hamiş provide a synchronized (thread safe) wrapper for a ReadOnlyCollectionBase, but derived classes kişi create their own synchronized versions of C# ReadOnlyCollectionBase Nedir the ReadOnlyCollectionBase using the SyncRoot property.

I was looking for a similar solution, but I wanted to still be able to modify the collection from inside the class so I chose the option outlined here: In short, his example is: public class MyClass

(There are plenty of other options for wrapping trivially - the nice thing about Skip over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
