使用路由概念将值从页面传递到页面 [英] passing a value from page to page using routing concept

问题描述

我有一个global.asax类文件，我在这里放置seo url路由概念：

 私人 静态  void  RegisterRoutes（RouteCollection路由）
 {
  //  有关url routing的更多信息http://www.codeproject.com/Articles/77199/URL-Routing-with-ASP-NET  
 routes.MapPageRoute（  ， ， 〜/ Default.aspx）; 
 routes.MapPageRoute（ ，   {categorySEOName}， 〜/ Pages.aspx）; 
 routes.MapPageRoute（ ，   {categorySEOName} / {subcategorySEOName}， 〜/ Pages.aspx）; 
} 

以及我如何从数据库获取数据并重写我的网址：

 public void LoadMenu（）
 {
 CategoryInfo _CateogyInfo = new CategoryInfo（）; 
 SubCategoryInfo _SubcateoryInfo = new SubCategoryInfo（）; 
列表<   CategoryInfo  >  categoryList = _CateogyInfo.GetCategory（）。ToList <   CategoryInfo  > （）; 
 StringBuilder sb = new StringBuilder（）; 
 string appname = Request.ApplicationPath ==/？ ：Request.ApplicationPath.ToString（）; 
 sb.Append（<   ul     id   ='  nav' > ）; 
 foreach（categoryList中的CategoryInfo类别）
 {
 string seourl = string.Format（{0} / {1}，appname，category.CategorySEOName）; 
 sb.Append（<   li   >  <   a     class   ='  hsubs'    href   =  + seourl + > + category.CategoryName +<   / a  > ）; 
 _SubcateoryInfo.CategoryId = category.CategoryId！= null？ category.CategoryId：0; 
 _SubcateoryInfo.CategoryId = Convert.ToInt32（Request [categoryId]）; 
列表<   SubCategoryInfo  >  SubcategoryList = _SubcateoryInfo.GetSubCategoryByCategoryId（）。ToList <   SubCategoryInfo  > （）; 
 if（SubcategoryList.Count> 0）
 {
 sb.Append（<   ul     class   ='  subs' > ）; 
 foreach（SubcategoryList中的SubCategoryInfo子类别）
 {
 seourl = string.Format（{0} / {1} / {2}，appname，category.CategorySEOName，subCategory.SubCategorySEOName） ; 
 sb.Append（<   li   >  <   a     href   =  + seourl + > + subCategory.SubCategoryName +<   / a  >  <   / li  > ）; 
} 
 sb.Append（<   / ul  > ）; 
} 
 
} 
 sb.Append（<   / ul  > ）; 
 MenuSubMenu.Text = sb.ToString（）; 
} 

现在我的kestion是如何获得用户请求的categoryId将页面传递给页面。

就像用户点击类别一样，我想获得该类别，并将其作为请求[CategoryId]传递到我的下一页。



这是我用来获取请求ID的方式：

 app.Context.RewritePath （〜/ Category.aspx？Id =+ url [url.Length  -  2] +& name =+ url [url.Length  -  1] .Replace（。aspx，）+& ; type = category）; 

现在如果我想获得请求的Id，我会将它传递给这样的变量：< br $>

 _ SubCategoryInfo.CategoryId = Convert.ToInt32（请求[  Id]）; 

但是你知道这不是seo友好的。

现在我想使用相同的想法来使用路由概念获取所请求的Id。

解决方案

Hi,

I have a global.asax class file where I am placing the seo url routing concept like this:

private static void RegisterRoutes(RouteCollection routes)
    {
        //More info about url routing http://www.codeproject.com/Articles/77199/URL-Routing-with-ASP-NET
        routes.MapPageRoute("", "", "~/Default.aspx");
        routes.MapPageRoute("", "{categorySEOName}", "~/Pages.aspx");
        routes.MapPageRoute("", "{categorySEOName}/{subcategorySEOName}", "~/Pages.aspx");
    }

and this how I am getting the data from database and rewrite my url:

public void LoadMenu()
   {
       CategoryInfo _CateogyInfo = new CategoryInfo();
       SubCategoryInfo _SubcateoryInfo = new SubCategoryInfo();
       List<CategoryInfo> categoryList = _CateogyInfo.GetCategory().ToList<CategoryInfo>();
       StringBuilder sb = new StringBuilder();
       string appname = Request.ApplicationPath == "/" ? "" : Request.ApplicationPath.ToString();
       sb.Append("<ul id='nav'>");
       foreach (CategoryInfo category in categoryList)
       {
           string seourl = string.Format("{0}/{1}", appname, category.CategorySEOName);
           sb.Append("<li><a class='hsubs' href=" + seourl + ">" + category.CategoryName + "</a>");
           _SubcateoryInfo.CategoryId = category.CategoryId != null ? category.CategoryId : 0;
           _SubcateoryInfo.CategoryId = Convert.ToInt32(Request["categoryId"]);
           List<SubCategoryInfo> SubcategoryList = _SubcateoryInfo.GetSubCategoryByCategoryId().ToList<SubCategoryInfo>();
           if (SubcategoryList.Count > 0)
           {
               sb.Append("<ul class='subs'>");
               foreach (SubCategoryInfo subCategory in SubcategoryList)
               {
                   seourl = string.Format("{0}/{1}/{2}", appname, category.CategorySEOName, subCategory.SubCategorySEOName);
                   sb.Append("<li><a href=" + seourl + ">" + subCategory.SubCategoryName + "</a></li>");
               }
               sb.Append("</ul>");
           }

       }
       sb.Append("</ul>");
       MenuSubMenu.Text = sb.ToString();
  }

Now my kestion is how can I get a categoryId requested by the user to pass it from page to page.
Like once a user click on category I want to get that categoryId and pass it as the request["CategoryId"] to my next page.

This is the way I used to get the requested Id :

app.Context.RewritePath("~/Category.aspx?Id=" + url[url.Length - 2] + "&name=" + url[url.Length - 1].Replace(".aspx", "") + "&type=category");

Now If I want to get the Id requested I will pass it to a variable like this:

_SubCategoryInfo.CategoryId = Convert.ToInt32(Request["Id"]);

But as u know this is not seo friendly.
Now I want to use the same idea to get the requested Id using routing concept.
