FindStandardName(UAQualifiedName,String) Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAUtilities Class > FindStandardName Method : FindStandardName(UAQualifiedName,String) Method
The qualified name for which the standard name should be found.

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).

The standard name that corresponds to the given qualified name.

The value of this parameter can be null (Nothing in Visual Basic).

Finds a standard name for a given OPC-UA qualified name.
