Type: System.Configuration.ConfigurationElement

A ConfigurationElement object at the current level containing a merged view of the properties.

Type: System.Configuration.ConfigurationElement

The parent ConfigurationElement object of the current element, or Nothing if this is the top level.

Type: System.Configuration.ConfigurationSaveMode

A ConfigurationSaveMode enumerated value that determines which property values to include.

The Unmerge method reverses the effect of merging configuration information from different levels of the configuration hierarchy. This allows configuration set at the current hierarchy level to be differentiated from that set at parent levels, before serialization.

Unmerge is called by the system on a new temporary element to compare the parent object and the source object. Based on the ConfigurationSaveMode value, it then sets the temporary object to contain the data that needs to be serialized. For details about save modes, see Minimal.
