我只是在做这在今天，类似下面的code应该（用一把umbraco。presentation.nodeFactory）工作，用它打电话-1节点ID来获得该网站的根节点，让它工作，它是一路下滑：

I was just doing this today, something like the below code should work (using umbraco.presentation.nodeFactory), call it with a nodeId of -1 to get the root node of the site and let it work it's way down:

private void DoSomethingWithAllNodesByType(int NodeId, string typeName)
{
    var node = new Node(nodeId);
    foreach (Node childNode in node.Children)
    {
        var child = childNode;
        if (child.NodeTypeAlias == typeName)
        {
            //Do something
        }

        if (child.Children.Count > 0)
            GetAllNodesByType(child, typeName);
    }
}
