Getting error in reading complex data using OPCFoundation.NetStanderd.Opc.Ua.Client.ComplexTypes.dll

[mysterynirav]

Hi there,

We are using OPCFoundation.NetStanderd.Opc.Ua.Client and OPCFoundation.NetStanderd.Opc.Ua.Client.ComplexTypes to develop our own OPCUA Client which can connect to the server and get data.

Using the latest version of OPCFoundation.NetStanderd.Opc.Ua.Client.ComplexTypes version 1.4.370.12, the complex type data we are getting array data in extension object, but on first time execution on typeSystemLoader.Load() taking more than 1 minute.

I've attached a screenshot below for you to look over.

When we upgrade the same OPCFoundation.NetStanderd.Opc.Ua.Client.ComplexTypes.dll to version 1.4.372.106, we get the data in Byte[] format. We want to know how can we get the data in the extension object as the previous version of the library.

I've attached a screenshot below for you to look over.

Hi @mysterynirav, the complex type support has been vastly improved since 370 to properly support arrays also in complex types.
As a sidenote, the complex type system needs only to be loaded once after a session was established. Or to optimize you can load the type system only for a specific type by providing the type id.

Could you share the following information about your server:
i) Is it using the 1.03 dictionary type system or the newer 1.04 DataTypeDefinition?
ii) If it returns just the byte[] in the ExtensionObject there is a problem decoding. Could you share the log output?
iii) If possible, please share the DataTypeDefinition of the type to allow to repro.

Hi @mregen To answer your question,

1. We are using the newer 1.04.6 DataTypeDefination i.e "http://opcfoundation.org/UA/" Version="1.04.6" PublicationDate="2020-04-14T00:00:00Z"
2. We have enabled the log and shared the log file here. Opc.Ua.SampleClient.log.txt
3. I didn't get you, what do you mean by DataTypeDefinition of the type, Do you need any specific DataTypeDefinition?
   I have attached a function that uses ComplexTypeSystem.
