Page 5: Iterate over the Local Database

Next, we'd like to write out all elements of the local database. This can be achieved with the following method ...

private static void WriteChildren(INode node, int depth)
{
    var indent = new string(' ', 2 * depth);

    foreach (var child in node.Children)
    {
        var childNode = child as INode;

        if (childNode != null)
        {
            Console.WriteLine("{0}Node {1}", indent, child.Identifier);
            WriteChildren(childNode, depth + 1);
        }
        else
        {
            var childParameter = child as IParameter;

            if (childParameter != null)
            {
                Console.WriteLine("{0}Parameter {1}: {2}", indent, child.Identifier, childParameter.Value);
            }
        }
    }
}

... which we call from Main() as follows ...

Copy

AsyncPump.Run(
    async () =>
    {
        using (var client = await ConnectAsync("localhost", 9000))
        using (var consumer = await Consumer<MyRoot>.CreateAsync(client))
        {
            WriteChildren(consumer.Root, 0);
        }
    });

... which produces the following output:
