create method node in code

[jxu2016]

hello:

Can you give an example of creating method node with input and output argument grammatically in C# code? I have a need to dynamically create the method nodes.

Thanks.

Hello,

The following method adds a UA Method node with InpurtArguments and OutputArguments properties to the Method folder in .NET DemoServer:

Code: Select all

private void CreateMethodInCode()
{
    CreateMethodSettings settings = new CreateMethodSettings()
    {
        ParentNodeId = new NodeId(Demo.Model.Objects.Demo_Method, DefaultNamespaceIndex),
        ReferenceTypeId = ReferenceTypeIds.HasComponent,
        RequestedNodeId = new NodeId("MethodInCode", DefaultNamespaceIndex),
        BrowseName = new QualifiedName("MethodInCode", DefaultNamespaceIndex),
        Executable = true,
        InputArguments = new List<Argument>(),
        OutputArguments = new List<Argument>()
    };

    settings.InputArguments.Add(new Argument()
    {
        DataType = DataTypeIds.Double,
        Name = "InputArgument1",
        Description = "The first input argument",
        ValueRank = ValueRanks.Scalar,
    });
    settings.InputArguments.Add(new Argument()
    {
        DataType = DataTypeIds.Double,
        Name = "InputArgument2",
        Description = "The second input argument",
        ValueRank = ValueRanks.Scalar,
    });

    settings.OutputArguments.Add(new Argument()
    {
        DataType = DataTypeIds.Double,
        Name = "Result",
        Description = "The output argument",
        ValueRank = ValueRanks.Scalar,
    });
    CreateMethod(Server.DefaultRequestContext, settings);
}
