true if an attempt to add a duplicate ConfigurationElement to this ConfigurationElementCollection will cause an exception to be thrown; otherwise, false.
Remarks
When you add a duplicate element, an exception is thrown if the CollectionType value of the element is either AddRemoveClearMap or AddRemoveClearMapAlternate.
Note that elements with identical keys and values are not considered duplicates, and are accepted silently. Only elements with identical keys but different values are considered duplicates. For more information, see the Remarks section for the BaseAdd method.
