ASP.NET MVC - Extract parameter of an URL

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

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"];

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.
