How can I define a structure type in an OPC-UA server?

I am using OPCFoundation.NetStandard.Opc.Ua.Server (version 1.5.377.22) and would like to:

1. Create a structure data type on the server.
2. Create a variable node of that data type on the server.
3. Set values for the variable on the server.

I want to do this programmatically in C#, without modelling node sets in another tool.

For demonstration purposes, the structure can be defined by a C# class Person, but I eventually want to create more complex classes containing enumerations and nested structures.

class Person  
{  
    string Name;  
    int Age;  
}

I'm basically looking for an answer like .net - How can I define an enum type in OPC-UA server? which perfectly did the job for enumerations.
