Url.Content in asp.net web-forms

问题:

I'm trying to do this:

<a href="~/Cases/SupRequestSearch.aspx">Search request</a>

so I need the ~ to be rendered as http://myserver/app/...

in mvc I would do

<a href="<%=Url.Content("~/Cases/SupRequestSearch.aspx")%>>Search request</a>

is there something similar in asp.net web forms ?

回答1:

Try adding runat="server" to your tag.

回答2:

As rapadai mentioned above, the equivalent of

Url.Content("~/path/to/file.ext") // MVC

in webforms is

Page.ResolveUrl("~/path/to/file.ext") // Webforms

回答3:

Try this:

<asp:hyperlink  id="Search" NavigateUrl="~/Cases/SupRequestSearch.aspx" runat="server" />

or just

<a href="~/Cases/SupRequestSearch.aspx" id="Search" runat="server">Search request</a>

回答4:

If you don't have either Url or Page you can still use

VirtualPathUtility.ToAppRelative(string) or VirtualPathUtility.ToAbsolute(string)

You still need to be within a web context of course - or this doesn't make sense.

<%= Page.ResolveUrl("~/Path/To/Page") %>
