Asp.Net System.Web.Routing Find actual .aspx Page

问题

I'm using System.Web.Routing to have some better URL's and have come across a problem. I need to know the actual page that's handling the request.

for example a request comes in as:

/basketball/home

I need to find the page that handles that request, like:

/management/default.aspx

I'm only using the System.Web.Routing and not MVC. I have a handle to the RequestContext that contains some of the route information, but i don't see what i need.

Thanks in advance.

******* UPDATE *******

I was able to use Context.CurrentHandler which give me "ASP.management_default_aspx", not exactly the page but enough to get the page name.

回答1:

There is actually another simple way to get the actual page:

String vPath = ((System.Web.Routing.PageRouteHandler)Page.RouteData.RouteHandler).VirtualPath
Do not forget to check Page.RouteData.RouteHandler is not null - while you are getting the page w/o ASP.Net routing but directly.

回答2:

Can you not retrieve this from the current HttpContext object?

Perhaps something like this:

public string GetCurrentPageName() 
{ 
    string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath; 
    System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath); 
    string sRet = oInfo.Name; 
    return sRet; 
}

UPDATE:
Have you tried this article?

You should be able to retrieve it back from the Routing table you have constructed.

vhinn terrible's answer worked...

Page.AppRelativeVirtualPath

You just have to remove the initial tilde ("~"), and you're ready to go.

var path = Page.AppRelativeVirtualPath.Replace("~", String.Empty);

I don't know why it was downvoted. Worked for me like a charm.

Try using this code:

Page.AppRelativeVirtualPath
