生成URL路由的Web表单的URL [英] Generate a URL with URL Routing in Webforms

问题描述

我知道在MVC框架，你的HTML类来创建网址：

I know in the MVC Framework, you have the Html Class to create URLs:

Html.ActionLink("About us", "about", "home");

但是，如果你想在Web表单生成URL是什么？

But what if you want to generate Urls in Webforms?

我还没有找到上生成与Web表单的URL的细节一个很好的资源

I haven't found a really good resource on the details on generating URLs with Webforms.

例如，如果我产生像这样的路线：

For example, if I'm generating routes like so:

Route r = new Route("{country}/{lang}/articles/{id}/{title}",
                  new ArticleRouteHandler("~/Forms/Article.aspx"));
Route r2 = new Route("{country}/{lang}/articles/",
                  new ArticleRouteHandler("~/Forms/ArticlesList.aspx"));

Routes.Add(r);
Routes.Add(r2);

我将如何产生使用路由表中的数据的URL。

How would i generate URLs using the Routing table data.

如。 / CA / EN /用品/ 123 /无

eg. /ca/en/articles/123/Article-Title without

推荐答案

至于你说的文章，标题，ASP.NET MVC为您提供了一组的辅助方法来反向查找的RouteTable，并为你生成一个URL。我没有这个出场不多但但据我可以看到你需要调用一个RouteCollection（最有可能RouteTable.Routes）的GetVirtualPath方法。因此，像：

As you say, ASP.NET MVC offers you a set of helper methods to "reverse lookup" the RouteTable and generate a URL for you. I've not played with this much yet but as far as I can see you need to call the GetVirtualPath method on a RouteCollection (most likely RouteTable.Routes). So something like:

Dim routedurl = RouteTable.Routes.GetVirtualPath(context, rvd).VirtualPath

您需要传递的RequestContext和RouteValueDictionary。该RouteValueDictionary包含路由参数（所以你的情况类似县=英国，LANG =EN-GB等最棘手的部分是RequestContext的，因为这是不正常的的HttpContext的一部分。你可以将其推入HttpContext的在你的IRouteHandler：

You need to pass the RequestContext and a RouteValueDictionary. The RouteValueDictionary contains the route parameters (so in your case something like county="UK", lang="EN-GB" etc. The tricky part is the RequestContext as this is not part of the normal HttpContext. You can push it into the HttpContext in your IRouteHandler:

requestContext.HttpContext.Items("RequestContext") = requestContext

，然后在你的IHttpHandler（aspx页面）重新恢复它在必要时：

and then restore it again in your IHttpHandler (aspx page) when required:

Dim rvd = 
  New RouteValueDictionary(New With {.country = "UK", .lang = "EN-GB"})
Dim routedurl = 
  RouteTable.Routes.GetVirtualPath(context.Items("RequestContext"), rvd).VirtualPath

道歉应对VB中的一个C＃的问题，它只是使ASP.NET路由网站我只好用手在VB.NET。

Apologies for responding to a C# question in VB, it was just that the ASP.NET routing site I had to hand was in VB.NET.
