ConfigurationElement.IsModified Method
Assembly: System.Configuration (in system.configuration.dll)
The IsModified method determines whether this ConfigurationElement object will be written to the configuration file when the Save method is called. If the return value is false, it is assumed that the configuration file represents the current state of the element.
By default, IsModified returns true after a property is set through the indexer to this ConfigurationElement object.
Override the IsModified method to provide custom indication of the state of this ConfigurationElement element.
