You can use Queue like what i had done in my application :

List nodes = new List();
Queue queue = new Queue();

//
// first insert all the root nodes into the queue.
//
foreach(TreeNode root in tree.Nodes) {
    queue.Enqueue(root);
}

while(queue.Count > 0) {
    TreeNode node = queue.Dequeue();
    if(node != null) {
        //
        // Add the node to the list of nodes.
        //
        nodes.Add(node);

        if(node.Nodes != null && node.Nodes.Count > 0) {
            //
            // Enqueue the child nodes.
            //
            foreach(TreeNode child in node.Nodes) {
                queue.Enqueue(child);
            }
        }
    }
}
