Episerver Commerce - Retrieving all parent catalog nodes

Update: Code sample updated to use GetCategories extension method, as suggested by Magnus Rahl in his comment. Let say you have a product "Puma Green Suede Athletic Sneakers Shoes" with the following categories:

Here is code that lists all nodes (of type NodeContent) that the product belongs to:

private List<string> GetNodes(ProductContent currentContent) { List<string> nodeList = new List<string>(); foreach (var nodeRelation in currentContent.GetCategories()) { var currentNode = _contentLoader.Get<NodeContent>(nodeRelation); if (currentNode != null) { AddParentNodes(currentNode, nodeList); } } return nodeList; } private void AddParentNodes(NodeContent currentNode, List<string> nodeList) { if (currentNode == null) { return; } if (!nodeList.Contains(currentNode.Code)) { nodeList.Add(currentNode.Code); } var nodeRelations = currentNode.GetCategories().ToList(); nodeRelations.Add(currentNode.ParentLink); foreach (var nodeRef in nodeRelations) { var node = _contentLoader.Get<CatalogContentBase>(nodeRef); AddParentNodes(node as NodeContent, nodeList); } }

Hopefully this will be a lot cleaner in the next major version of Episerver Commerce
