Hello.

Please post here the URL where the documentation tells you about such escaping. Either the documentation is wrong, or you are misinterpreting it. There is no specific escaping needed for the identifier part of the node Id.

Assuming that what you want is a node Id with namespace index 2 and a string identifier "Data Type Examples.8 Bit Device.K Registers.Boole:an4", it can be constructed like

 

new UANodeId("ns=2; s=Data Type Examples.8 Bit Device.K Registers.Boole:an4")

 

If you have the namespace index and the identifier separately already, there is no need to bother with formatting the node Id as text. Simply use

 

new UANodeId(2, "Data Type Examples.8 Bit Device.K Registers.Boole:an4")

 


Have you seen this example?:
