如果在數據庫中這些網址,你可以在應用程序啓動時的路線圖:
var pages = siteDB.Pages.ToList();
string pagePath = "";
foreach (var page in pages)
{
routeVals = new RouteValueDictionary();
constraints = new RouteValueDictionary();
routeVals.Add("controller", "page");
routeVals.Add("action", "details");
constraints.Add("path", "[a-zA-Z0-9\\-]*");
// any child pages? must add these routes before their parent pages.
var childPages = siteDB.Pages.Where(p => p.ParentPageId == page.PageId).ToList();
foreach (var childPage in childPages)
{
pagePath = BuildPath(childPage);
RouteTable.Routes.Add(new Route(pagePath, new MvcRouteHandler())
{
Defaults = routeVals,
Constraints = constraints,
DataTokens =
new RouteValueDictionary {
{ "pageid", childPage.PageId },
{ "path", pagePath }
}
});
// Any further child pages? (Only 3 levels supported)
var childSubPages = siteDB.Pages.Where(p => p.ParentPageId == childPage.PageId).ToList();
foreach (var childSubPage in childSubPages)
{
pagePath = BuildPath(childSubPage);
RouteTable.Routes.Add(new Route(pagePath, new MvcRouteHandler())
{
Defaults = routeVals,
Constraints = constraints,
DataTokens =
new RouteValueDictionary {
{ "pageid", childSubPage.PageId },
{ "path", pagePath }
}
});
}
}
此代碼需要從那裏它們被父ID連接數據庫的頁面。
這裏的構建路徑功能,產生用於每一頁的完整路徑:
public static string BuildPath(Page page)
{
if (page.ParentPageId == 1)
{
return page.PageKey;
}
else
{
SiteDataEntities siteDB = new SiteDataEntities();
string path = page.PageKey;
Page parent = siteDB.Pages.Find(page.ParentPageId);
while (parent != null)
{
path = parent.PageKey + "/" + path;
parent = siteDB.Pages.Find(parent.ParentPageId);
if (parent.PageKey == "home") break;
}
return path;
}
}
謝謝山姆,這是我正在尋找。非常感謝你=) – Zayar
嗨,山姆,BuildPath函數會做什麼? – Zayar
剛剛添加了BuildPath函數和解釋。 –
