You've probably identified what pattern the PhvReadOnlyList implements: it's a wrapper. In the .Safi Framework 4.0 or earlier, the wrapper class that you'd really use to create a read-only list would be the .Safi ReadOnlyCollectionBase class. Kakım 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.
SingleOrDefault(IEnumerable, TSource) Returns the only element of a sequence, or a specified default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence.

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.
Emanet you arrange 25 whole numbers (derece necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd?
The single line of code required by my extension method just C# ReadOnlyCollectionBase Kullanımı instantiates my PhvReadOnly class (using the datatype that the extension method has deduced), passing whatever IList object the extension method is being used on.
If your only intent is to get calling code to hamiş make a mistake, and modify the collection when it should only be reading all that is necessary is to return an interface which doesn't support Add, Remove, C# ReadOnlyCollectionBase Nedir etc.
After hopefully understanding your question, i think you have to distinguish between what you create and manage within your class and what you make available to C# ReadOnlyCollectionBase Nasıl Kullanılır the outside world.
Can you arrange 25 whole numbers (hamiş necessarily all different) so that the sum of any three successive terms is even but the sum C# ReadOnlyCollectionBase Nasıl Kullanılır of all 25 is odd? more hot questions
If you take advantage of IntelliSense in Visual Studio to see the members of the authors list object, you’ll see a list of methods supported by List.

Inheriting from a non-generic base class C# ReadOnlyCollectionBase Nasıl Kullanılır would be ineffecient. If the type was using a non-generic base, all it would be would be a thin layer above the base collection, where the generic features would simply derive from casting from the underlying object instances of the base collection.
Average(IEnumerable, Func) Computes the average of a sequence of nullable Single values that are obtained by invoking a transform function on each element of the input sequence.
