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 dirilik be avoided.
A note. Read-only status is hamiş transferred to other references. You cannot replace the references with other StringBuilder references or the null literal.
Example. In this izlence, a list of ints is created, and then the ReadOnlyCollection constructor is used with that List as an argument. Inside the ReadOnlyCollection constructor, a reference to the argument is stored birli an IList reference field.
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.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
When you write a For…Each loop to use with a collection, the compiler checks the collection class to see if it implements the IEnumerable interface (or the generic version of that interface, IEnumerable).

A method like PayUnpaidInvoices being present may lead to second guessings about what "regular" collection methods like Remove and Clear might do. Will it just remove invoices from the in-memory collection, or will it delete them from the database?
