ConfigurationAllowDefinition Enumeration

.NET Framework 4.5

Specifies the locations within the configuration-file hierarchy that can set or override the properties contained within a ConfigurationSection object.

Namespace: System.Configuration
Assembly: System.Configuration (in System.Configuration.dll)

public enum ConfigurationAllowDefinition

	Member name	Description
	MachineOnly	The ConfigurationSection can be defined only in the Machine.config file.
	MachineToWebRoot	The ConfigurationSection can be defined in either the Machine.config file or the machine-level Web.config file found in the same directory as Machine.config, but not in application Web.config files.
	MachineToApplication	The ConfigurationSection can be defined in either the Machine.config file, the machine-level Web.config file found in the same directory as Machine.config, or the top-level application Web.config file found in the virtual-directory root, but not in subdirectories of a virtual root.
	Everywhere	The ConfigurationSection can be defined anywhere.

The values in this enumeration are optionally used when creating a new instance of the ConfigurationSection class.
