HasProperty Method (UABrowsePathElement)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Navigation Namespace > UABrowsePathElement Class : HasProperty Method
The name of the target node.

Because the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the qualified name) in place of this parameter, and the corresponding OPC UA qualified name will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName.UAQualifiedName Constructor(String) constructor instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

Creates a new OPC-UA browse path element with given target name, specifying OpcLabs.EasyOpc.UA.AddressSpace.Standard.UAReferenceTypeIds.HasProperty reference, for following in forward direction, and including subtypes.
