c# - How to get all route-values after {controller}/{method} -

i render buttons in order change language following:

                    <%: html.actionlink(                         "en",                          viewcontext.routedata.values["action"].tostring(),                          new { lang = "en" }, new { @class="tab" })%> 

this render me link follows: {...}\en\mycontroller\mymethod - problem left lose routing values, follow after method's name. how possible add them well?

thanks tips!

i use few handy extension methods:

    public static routevaluedictionary toroutevaluedictionary(this namevaluecollection collection)     {         routevaluedictionary dic = new routevaluedictionary();         foreach (string key in collection.keys)             dic.add(key, collection[key]);          return dic;     }      public static routevaluedictionary addorupdate(this routevaluedictionary dictionary, string key, object value)     {         dictionary[key] = value;         return dictionary;     }      public static routevaluedictionary removekeys(this routevaluedictionary dictionary, params string[] keys)     {         foreach (string key in keys)             dictionary.remove(key);          return dictionary;     } 

this allows me following:

//update current routevalues , pass values. @html.actionlink("en", viewcontext.routedata.values["action"], viewcontext.routedata.values.addorupdate("lang", "en"))  //grab querystring, update value, , set routevalues. @html.actionlink("en", viewcontext.routedata.values["action"], request.querystring.toroutevaluedictionary.addorupdate("lang", "en"))
