ActionLink route values containing specific characters

Question

I am using this action-link to send a route value id to controller but my id value like this config.xml and here is my action-link

 @Html.ActionLink("Destroy", "DeleteFile", "Files", new { id = "config.xml"})

The question is when I want to click this link browser understand this as a url that ends with config.xml

like this

http://localhost:12380/Files/DeleteFile/config.xml

and doesn't go to the controller it returns 404 - not found. How to prevent this from happening and make this config.xml as a parameter not as a file?

here is my route also

routes.MapRoute(
              name: "delete files",
              url: "Files/DeleteFile/{id}",
              defaults: new
              {
                  controller = "Files",
                  action = "DeleteFile",
                  id= UrlParameter.Optional
              }
            );

also i tried instead id ,filename but nothing changed

and here is my controller

[HttpGet]
        public ActionResult DeleteFile(string id)
        {
          return view("DeleteFile");
         }

here is my action-result [HttpGet] public ActionResult DeleteFile(string id) { return view("DeleteFile"); } — Younis Qadir, Jan 08 '15 at 12:00
And how does your route look like? Maybe there is a "int"-contraint on it? — Christoph Fink, Jan 08 '15 at 12:04
here is my route routes.MapRoute( name: "delete files", url: "Files/DeleteFile/{id}", defaults: new { controller = "Files", action = "DeleteFile", id= UrlParameter.Optional } ); — Younis Qadir, Jan 08 '15 at 12:08

You can do it using this overload of Html.ActionLink() like this:

@Html.ActionLink("Destroy", 
                "DeleteFile", 
                "Files", 
                new RouteValueDictionary { {"file", Url.Encode("config.xml")} }, 
                null)

and Action:

public ActionResult DeleteFile(string file)
{
  // delete logic here
  return View();
}

From MSDN:

public static MvcHtmlString ActionLink(
    this HtmlHelper htmlHelper,
    string linkText,
    string actionName,
    string controllerName,
    RouteValueDictionary routeValues,
    IDictionary<string, Object> htmlAttributes
)

Here is a working DEMO Fiddle

@Younisbarznji don't use ``id`` as parameter use some other name like i used ``file``, id is changed by routing so it is considered file path – Ehsan Sajjad Jan 08 '15 at 12:19
the point is when i remove .xml from the parameter it is working fine but with .xml understands like a page – Younis Qadir Jan 08 '15 at 12:19
i also tried this i changed to strFileName but still the same – Younis Qadir Jan 08 '15 at 12:20
@Younisbarznji: What link is generated? It should be like `http://localhost:12380/Files/DeleteFile?file=config.xml` and that should work... – Christoph Fink Jan 08 '15 at 12:22
the link is http://localhost:12380/Files/DeleteFile/config.xml it is working like this ?file="config.xml" but i want to make it without using url like this ?file="config.xml" – Younis Qadir Jan 08 '15 at 12:26
also your demo i tried the link becomes like this //localhost:12380/Files/DeleteFile/config.xml – Younis Qadir Jan 08 '15 at 12:28
sure i putted in the question you can see it – Younis Qadir Jan 08 '15 at 12:38
@Younisbarznji remove ``DeleteFiles`` action route and then try – Ehsan Sajjad Jan 08 '15 at 13:10
@Ehsan Sajjad i removed but it got error to index file route – Younis Qadir Jan 08 '15 at 17:25
Do you have default route in it? – Ehsan Sajjad Jan 08 '15 at 17:28
Before making post I tested it on my machine also in fiddle, I think you are doing some other mistake – Ehsan Sajjad Jan 08 '15 at 17:54
what you think about ? when i remove .xml it is fine but with .xml gets error – Younis Qadir Jan 08 '15 at 17:57
It's related with routing I guess – Ehsan Sajjad Jan 08 '15 at 17:58
you see my route above is there any mistake , and why it works when remove .xml ? – Younis Qadir Jan 08 '15 at 18:02
Did you used file instead of id in view and action? – Ehsan Sajjad Jan 08 '15 at 18:03
Dear Ehsan i find a solution for this we can just put / after config.xml then it wokrs.. thank you for helping me also here is a link http://stackoverflow.com/questions/6534366/dot-character-in-asp-net-mvc-3-route-parameters – Younis Qadir Jan 12 '15 at 05:09
