ConfigurationElementCollection.Unmerge Method

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Reverses the effect of merging configuration information from different levels of the configuration hierarchy

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)
protected internal override void Unmerge(
	ConfigurationElement sourceElement,
	ConfigurationElement parentElement,
	ConfigurationSaveMode saveMode
)

Parameters

sourceElement
Type: System.Configuration.ConfigurationElement

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

parentElement
Type: System.Configuration.ConfigurationElement

The parent ConfigurationElement object of the current element, or null if this is the top level.

saveMode
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.
