Recursive adding XML into TreeView

Question

I\'m trying to import an XML file of nodes into the same node structure in a TreeView using C#. I have found a lot of example that use a single node structure, but have had a lo

Answer 1

I suggest recursion

void AddNodes(XElement parentElement, TreeNode parent = null)
{
    Queue queue = new Queue(parentElement.Elements());
    while (queue.Count > 0)
    {
        TreeNode child = parent;
        XElement element = queue.Dequeue();
        if (!element.HasElements)
        {
            string value = element.Value;
            element = (XElement)element.NextNode;
            if (null != element && !element.HasElements)
                value = element.Value;

            if (null == parent)
                treeView1.Nodes.Add(child = new TreeNode(value));
            else
                parent.Nodes.Add(child = new TreeNode(value));
            child.Expand();
            element = queue.Dequeue();
        }
        AddNodes(element, child);
    }
}

AddNodes(XElement.Load("ProductDocument.xml"));

Note: dbc's answer is probably better if your XML structure is likely to change, but if you are given it as it currently stands, and it won't change - then this will slurp it right into the tree quickly, without a lot of overhead.
