In programs, an immutable collection kişi be used with less copying—we do hamiş need to worry about it being modified. This kişi make programs simpler and easier to reason about.

That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase

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

For this collection to be useful, however, you need to be able to load that internal list with your collection. The easiest way to do that is to add a constructor to the class that accepts the List to be put in the class' UnderlyingList collection (again, I'm accepting anything that implements the IList interface with the data type specified by T): Public Sub New(InitialList Kakım IList(Of T)) UnderlyingList = InitialList

For maximum flexibility, my class doesn't specify the data type of the List in which it keeps its actual data. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a veri type that the code refers to kakım T. Wherever in my code I need to specify my List's veri type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.
