The following tables list the members exposed by NodeDescriptor.

Public Fields

	Name	Description
	DefaultAsString	Default NodeDescriptor, expressed as string. This is a constant, and its value is `"" (String.Empty)`.
	DefaultBrowsePath	Default browse path (`null`, i.e. none). This is a constant, and its value is `null`.
	DefaultNodePath	Default node path. Effectively, node path is specified. This is a constant, and its value is `null`.

Protected Fields

	Name	Description
	DefaultNodeId	Default node id (none, i.e. `null`). This is a constant, and its value is `null`.
	RootNodeId	A node Id that represents a root of the address space. An empty string. This is a constant, and its value is `"" (String.Empty)`.

Public Properties

	Name	Description
	AliasName	When non-empty, specifies the name of the alias that will be used in place of this object.
	ArgumentString	The node descriptor in form of an argument string, i.e. a key=value pairs separated by semicolons.
	BrowsePath	Specifies the browse path for the OPC node.
	BrowsePathStartingNodeDescriptor	The starting node descriptor of the browse path.
	HasBrowsePath	Determines whether there is a non-null browse path in the descriptor.
	HasNodeId	Determines whether there is a non-null node ID in the descriptor.
	IsAliased	Determines whether this object is aliased.
	IsNull	Determines whether the node descriptor is null, i.e. specifies neither node ID nor a browse path.
	IsRoot	Determines whether this object describes a root of the address space.
	NodeId	Contains node identifier (empty string for the root, null reference if unknown).
	NodePath	Contains node path (empty string for the root, null reference if unknown). Only used with OPC XML.
