正如the documentation说，你必须配置所有自定义路由参数（包括ID）明确。您可以通过将关键字包含在PreservedRouteParameters中来创建与操作方法的1对1关系，或者可以通过为每个路由值组合创建一个单独的节点，从而与该操作创建一对多关系。
1对1的关系
使用XML：
<mvcSiteMapNode title="News" controller="News" action="News" preservedRouteParameters="id"/>
或使用.NET Attributes：
[MvcSiteMapNode(Title = "News", ParentKey = "News", PreservedRouteParameters = "id")]
public ActionResult News(int id)
{
ViewBag.id = id;
return View();
}
注：使用此方法时，网址只能解决正确地在SiteMapPath HTML助手中，并且您可能需要手动修复节点的标题和可见性，如explained here。
1一对多的关系
使用XML：
<mvcSiteMapNode title="Article 1" controller="News" action="News" id="1"/>
<mvcSiteMapNode title="Article 2" controller="News" action="News" id="2"/>
<mvcSiteMapNode title="Article 3" controller="News" action="News" id="3"/>
或使用.NET Attributes：
[MvcSiteMapNode(Title = "Article 1", ParentKey = "News", Attributes = @"{ ""id"": 1 }")]
[MvcSiteMapNode(Title = "Article 2", ParentKey = "News", Attributes = @"{ ""id"": 2 }")]
[MvcSiteMapNode(Title = "Article 3", ParentKey = "News", Attributes = @"{ ""id"": 3 }")]
public ActionResult News(int id)
{
ViewBag.id = id;
return View();
}
或使用Dynamic Node Provider：
随着XML定义节点：
<mvcSiteMapNode title="News" controller="News" action="Index" key="News">
// Setup definition node in XML (won't be in the SiteMap)
// Any attributes you put here will be the defaults in the dynamic node provider, but can be overridden there.
<mvcSiteMapNode dynamicNodeProvider="MyNamespace.NewsDynamicNodeProvider, MyAssembly" controller="News" action="News"/>
</mvcSiteMapNode>
，或者在.NET定义节点属性：
// Setup definition node as a .NET Attribute (won't be in the SiteMap)
// Any properties you put here will be the defaults in the dynamic node provider, but can be overridden there.
[MvcSiteMapNode(DynamicNodeProvider = "MyNamespace.NewsDynamicNodeProvider, MyAssembly")]
public ActionResult News(int id)
{
ViewBag.id = id;
return View();
}
动态节点提供程序实现（对于上述2个定义节点的所需）：
public class NewsDynamicNodeProvider
: DynamicNodeProviderBase
{
public override IEnumerable<DynamicNode> GetDynamicNodeCollection(ISiteMapNode node)
{
using (var db = new EnityContext())
{
// Create a node for each news article
foreach (var news in db.News)
{
var dynamicNode = new DynamicNode();
dynamicNode.Title = news.Title;
dynamicNode.ParentKey = "News";
dynamicNode.RouteValues.Add("id", news.Id);
yield return dynamicNode;
}
}
}
}
