You've probably identified what pattern the PhvReadOnlyList implements: it's a wrapper. In the .NET Framework 4.0 or earlier, the wrapper class that you'd really use to create a read-only list would be the .Kupkuru ReadOnlyCollectionBase class. Bey with my example, you use the ReadOnlyCollectionBase class to create your own class with whatever functionality you need -- but you don't need to write the GetEnumerator method or create your own UnderlyingList because the ReadOnlyCollectionBase handles both.

 

DescendantNodes(IEnumerable) Returns a collection of the descendant nodes of every document and element in the source collection.

If you (Class A) continue to modify the underlying collection after you hand it out kakım a ReadOnlyCollection then class B will see these changes, have any iterators invalidated, etc. and generally be open to any of the usual concurrency issues with collections.

The IReadOnlyDictionary interface provides a read-only view of a dictionary and represents a read-only collection of key/value pairs. The following code snippet illustrates how you yaşama define an IReadOnlyDictionary instance.

Average(IEnumerable, Func) Computes the average of a sequence of Double values that are obtained by invoking a C# ReadOnlyCollectionBase Nerelerde Kullanılıyor transform function on each element of the input sequence.

Bu makalede, C# metotlarının niye kullanıldığı, ne sorune yaradığı ve nasıl özellikler sunduğu karşı henüz detaylı vukuf vereceğim.

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

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

Figure 1 below displays the members of List. Note that you have C# ReadOnlyCollectionBase Kullanımı a method named Add, so you sevimli easily add authors to the list of authors we’ve created in the preceding code snippet.

Public static (Shared in Visual Basic) members of this type C# ReadOnlyCollectionBase Nasıl Kullanılır are thread safe. Any instance members are not guaranteed to be thread safe.

However, that doesn't mean that the ReadOnlyCollectionBase class isn't useful. For instance, by leveraging the InnerList property, you C# ReadOnlyCollectionBase Temel Özellikleri güç create a collection that supports whatever custom functionality you need. Perhaps you want to create a collection for audit log entries where users sevimli add but hamiş remove items.

ObservableCollection hayat 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 however 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.
