You can pass the attribute ID as a parameter to one of the ReadValue (extension) methods.
' This example shows how to read a value of a specific attribute of a single node, and display it.
Imports OpcLabs.EasyOpc.UA
Namespace UADocExamples._EasyUAClient
    Partial Friend Class ReadValue
        Public Shared Sub Overload2()
            ' Define which server and node we will work with.
            Dim endpointDescriptor As UAEndpointDescriptor = _
                    ""  ' or "opc.tcp://"
            Dim nodeDescriptor As UANodeDescriptor = "nsu=;i=10853"
            ' Instantiate the client object.
            Dim easyUAClient = New EasyUAClient()
            ' Obtain value of a DataType attribute.
            Dim value As Object = easyUAClient.ReadValue(endpointDescriptor, nodeDescriptor, UAAttributeId.DataType)
            ' Display results
            Console.WriteLine("value type: {0}", value.GetType())
            Console.WriteLine("value: {0}", value)
        End Sub
    End Class
End Namespace
