ConfigurationElementCollectionType

Specifies the type of a ConfigurationElementCollectionType object.

The default type of ConfigurationElementCollection. Collections of this type contain elements that can be merged across a hierarchy of configuration files. At any particular level within such a hierarchy, add, remove, and clear directives are used to modify any inherited properties and specify new ones.

Same as AddRemoveClearMap, except that this type causes the ConfigurationElementCollection object to sort its contents such that inherited elements are listed last.

Collections of this type contain elements that apply to the level at which they are specified, and to all child levels. A child level cannot modify the properties specified by a parent element of this type.

Same as BasicMap, except that this type causes the ConfigurationElementCollection object to sort its contents such that inherited elements are listed last.
