在ASP.net MVC控制器中使用Url.Content

Question

I'm using Url.Content("~/something.jpg") to get an absolute path in a view without problem.

I would like to use it in a controller but it doesn't work. It returns "/something.jpg" instead of " http://www.mydomain.com/something.jpg ".

I tried several tricks found on google and stackoverflow without success.

Why Url.Content() doesn't work in a controller ?

Any idea will be helpful.

Thank you

Answer 1

I am not sure why this is not working in controller probably because Url.Content is an mvc helper but I now how you can do what you want.If you want to get absolute path to your file you can try something like this:

var url=Path.Combine(Server.MapPath("../uploads"), "something.jpg");

In conclusion I think that what you need is Server.MapPath()

Answer 2

I finally found what i'm looking for by using new Uri(Request.Url, Url.Content("~/something.jpg")); . It returns :

http://www.mydomain.com/something.jpg ;

Using only Url.Content() in a controller seems to be not enough. We have to use the Uri class to have the full URL.

Anyway, thank you everybody for your help

You could have a config entry that holds your URL, and append that to the front...

var sUrlPublication = ConfigHelper.SiteUrl + Url.Content("~/....");

Add the URL to AppSettings ...

<appSettings>
  <add key="SiteURL" value="...."/>
</appSettings>

You could add a ConfigHelper class...

using System.Configuration;

public static class ConfigHelper
{
  public static string SiteUrl
    {
      get { return ConfigurationManager.AppSettings["SiteURL"]; }
    }
}

EDIT : Or as mentioned by Robert

var sUrlPublication = Request.Url.Host  + Url.Content("~/....");
