NotSupportedException

Always thrown if the property is set.

Because the collection is read-only, you can only get this item at the specified index. An exception will occur if you try to set the item. This member is an explicit interface member implementation. It can be used only when the ReadOnlyCollection<T> instance is cast to an IList<T> interface.
