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 .Kemiksiz Framework 4.5 you kişi use the read-only collections that Eric Vogel covered in an earlier C# Corner column, "The New Read-Only Collections in .Kemiksiz 4.5," to define that property. My client, however, was working with the .Safi Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .Kemiksiz you güç 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 hayat add items to but hamiş remove items from), inheriting from the ReadOnlyCollectionBase class makes that very easy to do.

Objects everywhere), and it makes the construction wordier (can't use .ToList or collection initializers). And it doesn't really communicate intent either: such a list suggests you could add/remove values, or change them: but that's not typical usage at all.

As I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does hamiş allow the user to modify the collection. So if the C# ReadOnlyCollectionBase Kullanımı IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I C# ReadOnlyCollectionBase Temel Özellikleri missing something?

Thous leads that your consumer classes are just awaiting interfaces instead of concrete classes and so you birey change the concrete C# ReadOnlyCollectionBase Nasıl Kullanılır implementation at a later stage without breaking your public contract (due to performance reasons use an List instead of a LinkedList or vice versa).

Exposing a ReadOnlyCollection kakım anything other than itself isn't necessary: after all, exposing it kakım an IList just gets confusing (where'd I get this IList from - can I modify it?), and any IList is exposable kakım ReadOnlyCollection so there's no loss of generality.

Now the error makes sense, it's true I do derece have a default constructor. However I am able to Serialize a ReadOnlyCollection using the DataContractSerializer even though ReadOnlyCollection does derece have a parameterless default constructor.

Average(IEnumerable, Func) Computes the average of a sequence of nullable Int64 values that are obtained by invoking a transform function on each element of the input sequence.

Does this double well potential contradict the fact that there is C# ReadOnlyCollectionBase Kullanımı no degeneracy for one-dimensional bound states?

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?
