DANodeElement Constructor(DANodeDescriptor)



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess.AddressSpace Namespace > DANodeElement Class > DANodeElement Constructor : DANodeElement Constructor(DANodeDescriptor)
The node descriptor to use the information from.

Because the OpcLabs.EasyOpc.DataAccess.DANodeDescriptor has an implicit conversion from System.String and DANodeElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the qualified name of the node), or a DANodeElement object (result from OPC browsing), in place of this parameter, and the corresponding OPC DA node descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromString or FromDANodeElement static method instead.

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

Initializes a new instance of the node element, with information from given node descriptor.
