Could not load nodes from resource (Opc.Ua.Sdk.ServiceResultException) #723

Closed NakWarsi closed 5 years ago

NakWarsi commented 5 years ago

I am trying to load NodeSets from a binary file, I tried a few formats of binary files (.uanodes, .ua, .tt2pro etc) to make sure that if there is not any issue with file format but every time I am getting the same exception at the time of uploading resource. Code:

          NodeStateCollection predefinedNodes = new NodeStateCollection();
                predefinedNodes.LoadFromBinaryResource(context,
                    "umati.tt2pro",
                    typeof(ServerNodeManager_Binary).GetTypeInfo().Assembly,
                    true);
                return predefinedNodes;

Exception:

Opc.Ua.Sdk.ServiceResultException
  HResult=0x80131500
  Message=Could not load nodes from resource: umati.tt2pro
  Source=Opc.Ua.Sdk.Core
  StackTrace:

   at abc.OPCUA.Server.ServerNodeManager_Binary.LoadPredefinedNodes(ISystemContext context) in C:\Users\Wars_Nau\source\repos\CycloidGearClosedLoop\src\UAServer\NodeManagers\ServerNodeManager_Binary.cs:line 66

   at Opc.Ua.Sdk.Server.MasterNodeManager.Startup()

I don't know where I am missing, any kind of assistance is highly appreciable.

Hello @NakWarsi,

.tt2pro is a UnifiedAutomation UAModeler project file. To load nodes into the stack you'll need a NodeSet2 XML file (you can generate it via the UAModeler) or a uanodes file.

Are you sure that you have tried it with a valid uanodes file? You could try to load a example file contained in this repo (e.g. Quickstarts.Boiler.PredefinedNodes.uanodes) to verify that your code is working and afterwards run the same code with your uanodes file.

Yes i tried .uanodes as well with the same project reference you have provided above but still i am getting the same issue.

According to the source code the file you want to load is not found in the embedded resources. (see here)

  1. Please check if you have marked the uanodes file as embedded resource
  2. Please check if the name of the embedded resource is correct. (Note that the format is [assembly name].[resource name])

Thank You @MD-V
