示例1: GetCurrentNode
/// <summary>
/// This determines the deepest node matching the current HTTP context, so if the current URL describes a location
/// deeper than the site map designates, it will determine the closest parent to the current URL and return that
/// as the current node. This allows menu relevence when navigating deeper than the sitemap structure designates, such
/// as when navigating to MVC actions, which are not shown in the menus
/// </summary>
/// <param name="selectedSiteMapProvider">the current MVC Site Map Provider</param>
/// <returns></returns>
public static ISiteMapNode GetCurrentNode(ISiteMap selectedSiteMap)
{
// get the node matching the current URL location
var currentNode = selectedSiteMap.CurrentNode;
// if there is no node matching the current URL path,
// remove parts until we get a hit
if (currentNode == null)
{
var url = HttpContext.Current.Request.Url.LocalPath;
while (url.Length > 0)
{
// see if we can find a matching node
currentNode = selectedSiteMap.FindSiteMapNode(url);
// if we get a hit, stop
if (currentNode != null) break;
// if not, remove the last path item
var lastSlashlocation = url.LastIndexOf("/");
if (lastSlashlocation < 0) break; // protects us from malformed URLs
url = url.Remove(lastSlashlocation);
}

/// <returns></returns>
