What is the equivalent to Page.ResolveUrl in ASP.NET MVC?

What is the equivalent to Page.Re开发者_如何学运维solveUrl in ASP.NET MVC available in the Controller?

It is Url.Content:

ASPX:

<link rel="stylesheet" href="<%= Url.Content("~/Content/style.css") %>" type="text/css" />

Razor:

<link rel="stylesheet" href="@Url.Content("~/Content/style.css")" type="text/css" />

This should do what you're looking for...

System.Web.VirtualPathUtility.ToAbsolute("~/")

Here are a whole bunch of ways to resolve a path that uses that application root operator (~)

• UrlHelper.Content
• HttpServerUtility.MapPath
• WebPageExecutingBase.Href
• VirtualPathUtility.ToAbsolute
• Control.ResolveUrl

To call any method with inline code on an asp.net page, the method either needs to be exposed as an instance variable on the current object, or available as a static/shared method.

A typical MVC page gives us access to quite a few of these as properties via the WebViewPage. Ever wonder when you type @ViewData, you get magically wired up to the ViewData? That's because you have hit a property exposed by the MVC page you're on.

So to call these methods, we don't necessarily refer to the type they represent, but the instance property that exposes them.

We can call the above instance methods like this (respectively):

href="@Url.Content("~/index.html")" 
href="@Server.MapPath("~/index.html")" 
href="@Href("~/index.html")" 

We can do this to call a shared method that doesn't need an instance:

href="@VirtualPathUtility.ToAbsolute("~/index.html")"

AFAIK, an MVC page doesn't automatically create an instance of anything from the System.Web.UI namespace, from which ResolveUrl inherits. If, for some reason, you really wanted to use that particular method, you could just new up a control and use the methods it exposes, but I would highly recommend against it.

@Code
    Dim newControl As New System.Web.UI.Control
    Dim resolvedUrl = newControl.ResolveUrl("~/index.html")
End Code
href="@resolvedUrl" 

That all said, I would recommend using @Url.Content as it fits best with MVC paradigms

UrlHelper.Content() does the same thing as Control.ResolveUrl().

You don't need to do this anymore in Razor v2.0/ASP.NET MVC 4.

Just use the "~" in a razor page and it will resolve it for you.

<link rel="stylesheet" href="~/Content/style.css" type="text/css" />

In my case, I find @Href not being enough in the way it deals with query strings in a URL. I prefer to wrap it inside the Raw method:

<script>
var isKendoWindow = false;
var myTimeOut;
clearTimeout(myTimeOut);
var sessionTimeout = (@Session.Timeout * 60000) - 5;
function doRedirect() {
    if (!isKendoWindow)
        window.location.href = '@Html.Raw(Href("~/Logon.aspx?brandid=" + SessionController.LandingBrandId + "&errCode=5055"))';
}
myTimeOut = setTimeout('doRedirect()', sessionTimeout);
</script> 

Or you can create your own version like this:

 public static IHtmlString ResolveUrl(this HtmlHelper htmlHelper, string url)
 {    
     var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext);
     return htmlHelper.Raw(urlHelper.Content(url));
 }

Another way to solve this issue:

Resolve the url in a code block at the top of the page or in code behind.

@page
@model IndexModel
@{
    ViewData["Title"] = "Home page";
    Layout = "~/Pages/Shared/_IndexLayout.cshtml";
    String img1 = Url.Content("~/img/people11.jpg");
}

Then use the variable in the html.

<div class="col-12 col-lg-8" style="background-image: url('@img1');"> </div>

Server.MapPath() //returna full path

or

url.content()

try using Server.MapPath().
