hi ，How can C # connect via OPC UA ？Imitating OPC DA to create connection is wrong，Are there any other ways or ideas?

    Are you able to explain what you are trying to do?
    e.g. do you want to implement an OPC UA client in C# that runs on a Windows PC?

    OK, that's not specific to PLCnext Technology, or to Phoenix Contact.

    You will probably want to use an SDK or Toolkit to develop the OPC UA client. There are some listed here, for .NET and for .NET Core:

    You probably don't want to implement a UA client from scratch, but that is another possibility if you have access to the specifications from the OPC Foundation.
