I have a simple Sitemap like this from asp:SiteMapDataSource:

Page 1 > Page 2 > Page 3

I would like to create foreach loop in C# that generates it instead for using asp:SiteMapPath because I need to add some exceptions to it. Now I cannot figure out how do I loop backwards from SiteMap.CurrentNode to SiteMap.RootNode?

+3  A: 

The property you are looking for is SiteMapNode.ParentNode

SiteMapNode currentNode = SiteMap.CurrentNode;
SiteMapNode rootNode = SiteMap.RootNode;
Stack<SiteMapNode> nodeStack = new Stack<SiteMapNode>();

while (currentNode != rootNode)

    currentNode = currentNode.ParentNode;

// If you want to include RootNode in your list

SiteMapNode[] breadCrumbs = nodeStack.ToArray();

Thanks almost working. But how do I reverse this loop as the output starts from current node and not from root?
Use a Stack<SiteMapNode>, and Push() each node onto the Stack. Stack<>.ToArray() will then return an array in the order you are looking for.

I've updated the example to include the Stack
