The following is the correct overload  in your example you are missing a closing   to the routeValues anonymous object so your code will throw an exception     lt a href   lt    Url Action  GetByList    Listing   new   name    John   contact    calgary  vancouver       gt   gt       lt span gt People lt  span gt   lt  a gt    Assuming you are using the default routes this should generate the following markup    lt a href   Listing GetByList name John amp amp contact calgary 2C 20vancouver  gt       lt span gt People lt  span gt   lt  a gt    which will successfully invoke the GetByList controller action passing the two parameters   public ActionResult GetByList string name  string contact

you can returns a private collection named HttpValueCollection even the documentation says it s a NameValueCollection using the ParseQueryString utility   Then add the keys manually  HttpValueCollection do the encoding for you  And then just append the QueryString manually    var qs   HttpUtility ParseQueryString       qs Add  name    John   qs Add  contact    calgary    qs Add  contact    vancouver     lt a href   lt    Url Action  GetByList    Listing    gt   lt   qs  gt   gt       lt span gt People lt  span gt   lt  a gt
