ASP.NET MVC - Extract parameter of an URL

Question

I'm trying to extract the parameters of my URL, something like this.

/Administration/Customer/Edit/1

extract: 1

/Administration/Product/Edit/18?allowed=true

extract: 18?allowed=true

/Administration/Product/Create?allowed=true

extract: ?allowed=true

Someone can help? Thanks!

Answer 1

Update

RouteData.Values["id"] + Request.Url.Query

Will match all your examples

---

It is not entirely clear what you are trying to achieve. MVC passes URL parameters for you through model binding.

public class CustomerController : Controller {

  public ActionResult Edit(int id) {

    int customerId = id //the id in the URL

    return View();
  }

}


public class ProductController : Controller {

  public ActionResult Edit(int id, bool allowed) { 

    int productId = id; // the id in the URL
    bool isAllowed = allowed  // the ?allowed=true in the URL

    return View();
  }

}

Adding a route mapping to your global.asax.cs file before the default will handle the /administration/ part. Or you might want to look into MVC Areas.

routes.MapRoute(
  "Admin", // Route name
  "Administration/{controller}/{action}/{id}", // URL with parameters
  new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults

If it's the raw URL data you are after then you can use one of the various URL and Request properties available in your controller action

string url = Request.RawUrl;
string query= Request.Url.Query;
string isAllowed= Request.QueryString["allowed"];

It sounds like Request.Url.PathAndQuery could be what you want.

If you want access to the raw posted data you can use

string isAllowed = Request.Params["allowed"];
string id = RouteData.Values["id"];

Answer 2

public ActionResult Index(int id,string value)

This function get values form URL After that you can use below function

Request.RawUrl - Return complete URL of Current page

RouteData.Values - Return Collection of Values of URL

Request.Params - Return Name Value Collections

Answer 3

You can get these parameter list in ControllerContext.RoutValues object as key-value pair.

You can store it in some variable and you make use of that variable in your logic.

Answer 4

I wrote this method:

    private string GetUrlParameter(HttpRequestBase request, string parName)
    {
        string result = string.Empty;

        var urlParameters = HttpUtility.ParseQueryString(request.Url.Query);
        if (urlParameters.AllKeys.Contains(parName))
        {
            result = urlParameters.Get(parName);
        }

        return result;
    }

And I call it like this:

string fooBar = GetUrlParameter(Request, "FooBar");
if (!string.IsNullOrEmpty(fooBar))
{

}
