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 gönül be avoided.

 

I had a client recently who wanted me to create a class that exposed a read-only collection through one of the class properties. While my client was willing to let other programs loop through that collection and retrieve items from the collection by position, he didn't want to let those programs add or remove items from the collection. In the Microsoft .Safi Framework 4.5 you hayat use the read-only collections that Eric Vogel covered in an earlier C# Corner column, "The New Read-Only Collections in .NET 4.5," to define that property. My client, however, was working with the .Kemiksiz Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .Kupkuru you dirilik also create a read-only class from an existing List just by calling your List's AsReadOnly method. However, if you need something special (a List that users kişi add items to but not remove items from), inheriting from the ReadOnlyCollectionBase class makes that very easy to do.

Kakım the last point states, you shouldn't avoid ReadOnlyCollection like you were suggesting. It is a very useful type to use for public members to inform the consumer of the C# ReadOnlyCollectionBase Nedir limitations of the collection they are accessing.

; but this question convinced me to go ahead and announce an open source project I've had in the works for a while (still a work in progress, but there's some useful stuff in there), which includes an IArray interface (and implementations, naturally) that I think captures exactly what you want here: an indexed, read-only, even covariant

Sum(IEnumerable, Func) Computes the sum of the sequence of Int64 values that are obtained by invoking a transform function on each C# ReadOnlyCollectionBase Nedir element of the input sequence.

So when i have this piece of code what is the easiest or best way to make it a read only collection?

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). If the class does implement that interface, then the compiler calls the single method that the interface forces the class to have: the GetEnumerator method.

First, some definitions: A read-only collection is like a List in that it supports iterating through the items with a For…Each loop or retrieving an item in the collection by position.
