Assembly: mscorlib (in mscorlib.dll)
The following code example demonstrates several members of the ReadOnlyCollection(T) class. The code example creates a List(T) of strings and adds four dinosaur names to it. The code example then wraps the list in a ReadOnlyCollection(T).
After demonstrating the Count, Contains, Item, and IList.IndexOf members, the code example shows that the ReadOnlyCollection(T) is just a wrapper for the original List(T) by adding a new item to the List(T) and displaying the contents of the ReadOnlyCollection(T).
Finally, the code example creates an array larger than the collection and uses the CopyTo method to insert the elements of the collection into the middle of the array.
