With this type from System.Collections.ObjectModel, we provide a collection of elements that cannot be changed. But it may be possible to change some elements themselves.

C# IStructuralEquatable arabirimini uygulayan bir dershane ile yapısal muadele kontrolörü nasıl yapılır? Aşağıdaki örnekte bu mevzuyu detaylı olarak görebilirsiniz:
Sum(IEnumerable, Func) Computes the sum of the sequence of Single values that are obtained by invoking a transform function on each element of the input sequence.
Well, there is a way. It ain't pretty kakım it adds extra stuff on your domain biçim, but I just checked and it works.
Is there any reason to expose an internal collection bey a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection?
Use ObservableCollection/ListViewCollection and make your own custom ReadOnlyObservableCollection wrapper like in #1 that doesn't implement Add or modifying properties and methods.
protected virtual ICollection EmployeesInternal get; private kaş; = new List(); // this will expose collection contents to public, seemingly unneccessary `Skip` statement will prevent casting back to Collection

Exposing a ReadOnlyCollection birli anything other than itself isn't necessary: after all, exposing it as C# ReadOnlyCollectionBase Temel Özellikleri 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.
In Visual Basic, an extension method must be declared inside a Module and decorated with the Extension attribute. Its first parameter specifies the kind of object to which it will attach itself. C# ReadOnlyCollectionBase Temel Özellikleri I want my extension method to appear in the IntelliSense dropdown lists for any class that implements the IList interface, so I'll declare the method's first (and only) parameter kakım C# ReadOnlyCollectionBase Nerelerde Kullanılıyor IList(of T) -- the compiler will figure out the type that T represents based on the List passed to my method.
C# metotları, C# ReadOnlyCollectionBase Kullanımı kodun henüz birleştirme olmasını sağlar, henüz endamsız ve elan okunabilir bir şekilde alfabelmasına yardımcı evet ve projenize daha zait konulevsellik kazandırır.
So, what's the best-practice way to deal with the bog-standard task of making small collections to pass around values? Should array be preferred over List where C# ReadOnlyCollectionBase Nerelerde Kullanılıyor possible?

Initializes a new instance of the ReadOnlyCollection class that is a read-only wrapper around the specified list.
