But yeah, I would have to agree that there's definitely a "hole" in the BCL where a read-only indexed collection interface should go. IList is just too multi-purpose.
An instance of the ReadOnlyCollection generic class is always read-only. A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes. See Collection for a modifiable version of this class.
NET 4.5, you may want to try the new read-only collection interfaces. You'll still want to wrap the returned collection in a ReadOnlyCollection if you're paranoid, but now you're hamiş tied to a specific implementation.
Equals metodunda, Point3D dershaneının X, Y ve Z bileğerlerinin öteki nöbetçi ile aynı olup olmadığı denetleme edilir. GetHashCode metodunda ise nesnenin hash kodu oluşturularak yapısal muadele katlaştırmalarında kullanılır.
This base class is provided to make it easier for implementers to create a generic read-only custom collection. Implementers are encouraged to extend this base class instead of creating their own.
Average(IEnumerable, Func) Computes the average of a sequence of Int32 values that are obtained by C# ReadOnlyCollectionBase Nasıl Kullanılır invoking a transform function on each element of the input sequence.
Ancestors(IEnumerable) Returns a collection of elements that contains the ancestors of every node in the source collection.
HashTable hash kodlarına bakılırsa dizdiğinden sınırlı bir sıralaması yoktur.Algoritması bu kodların süresince gizlidr. Dictionary ise verilerin ekleniş sırasını hiç değmaslahattirmeden saklamıştır.
Any idea why IList doesn't inherit from ICollection? Since the latter is basically IEnumerable plus Count, and since IList already has a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would have allowed someone with an IList to know how many items to expect from an enumeration.
jasonjason 240k3535 gold badges431431 silver badges529529 bronze badges 2 Really, IEnumerable özgü the same issue bey IList in principle, but implementing a single extra method (and a single extra property on the enumerator) was not considered a burden, compared to the dozens you would need for C# ReadOnlyCollectionBase Nasıl Kullanılır IList (which List and indeed ReadOnlyCollection do implement, separately from their generic collection interfaces)
Implementers are encouraged to extend this base class instead of creating their own. Members of this base class are protected and are intended to be used through a derived class only.
Nodes(IEnumerable) Returns a collection of the child nodes C# ReadOnlyCollectionBase Nasıl Kullanılır of every document and element in the source collection.
ObservableCollection birey bind to ListViewCollection in such a way that changes to ListViewCollection do hamiş get pushed back into ObservableCollection. The original ReadOnlyObservableCollection, however, throws an exception if you try to modify the collection.
If C# ReadOnlyCollectionBase Nasıl Kullanılır however C# ReadOnlyCollectionBase Temel Özellikleri your intent is to prevent the calling code from observing updates from other threads you'll have to fall back to solutions already mentioned, to perform a deep or shallow copy depending on your need.
