If your parameter happens to be a complex object  this solves the problem  The key is the RouteValueDictionary constructor   return RedirectToAction  Action   new RouteValueDictionary Model     If you happen to have collections  it makes it a bit trickier  but this other answer covers this very nicely

MVC 4 example     Note that you do not always have to pass parameter named ID  var message   model UserName     - thanks for taking yourtime to register on our glorious site     return RedirectToAction  ThankYou    Account   new   whatever   message       And   public ActionResult ThankYou string whatever            ViewBag message   whatever          return View         Of course you can assign string to model fields instead of using ViewBag if that is your preference

This might be years ago but anyways  this also depends on your Global asax map route since you may add or edit parameters to fit what you want   eg   Global asax       public static void RegisterRoutes RouteCollection routes                routes IgnoreRoute   resource  axd   pathInfo              routes MapRoute               Default      Route name               controller   action   id       URL with parameters               new   controller    Home   action    Index   id   UrlParameter Optional              new   controller    Home   action    Index   id   UrlParameter Optional                    extraParam   UrlParameter Optional    extra parameter you might need                     then the parameters you ll need to pass will change to   return RedirectToAction   Main   new RouteValueDictionary       new   controller   controllerName  action    Main   Id   Id  extraParam   someVariable

It is also worth noting that you can pass through more than 1 parameter   id will be used to make up part of the URL and any others will be passed through as parameters after a   in the url and will be UrlEncoded as default   e g   return RedirectToAction  ACTION    CONTROLLER   new              id   99  otherParam    Something   anotherParam    OtherStuff                So the url would be        CONTROLLER ACTION 99 otherParam Something amp anotherParam OtherStuff   These can then be referenced by your controller   public ActionResult ACTION string id  string otherParam  string anotherParam          Your code

The following succeeded with asp net core 2 1   It may apply elsewhere   The dictionary ControllerBase ControllerContext RouteData Values is directly accessible and writable from within the action method   Perhaps this is the ultimate destination of the data in the other solutions   It also shows where the default routing data comes from      Route   to  email      public IActionResult ToAction string email        return View  To   email      Route   from    public IActionResult FromAction         ControllerContext RouteData Values Add  email    mike myemail com        return RedirectToAction nameof ToAction                will redirect to  to mike myemail com    Route   FromAnother  email       public IActionResult FromAnotherAction string email        return RedirectToAction nameof ToAction                will redirect to  to  lt whatever the email param says gt              no need to specify the route part explicitly

Kurt s answer should be right  from my research  but when I tried it I had to do this to get it to actually work for me   return RedirectToAction   Main   new RouteValueDictionary       new   controller   controllerName  action    Main   Id   Id          If I didn t specify the controller and the action in the RouteValueDictionary it didn t work   Also when coded like this  the first parameter  Action  seems to be ignored  So if you just specify the controller in the Dict  and expect the first parameter to specify the Action  it does not work either   If you are coming along later  try Kurt s answer first  and if you still have issues try this one

If one want to Show error message for  httppost  then he she can try by passing an ID using  return RedirectToAction  LogIn    Security   new    errorId   1       for Details like this   public ActionResult LogIn int  errorId                        if  errorId  gt  0                                ViewBag Error    UserName Or Password Invalid                               return View                Httppost  public ActionResult LogIn FormCollection form                        string user  form  UserId                string password   form  Password                if  user     admin   amp  amp  password     123                                return RedirectToAction  Index    Admin                              else                               return RedirectToAction  LogIn    Security   new    errorId   1                       Hope it works fine

I had this issue as well  and quite a nice way to do it if you are within the same controller is to use named parameters   return RedirectToAction actionName   Action   routeValues  new   id   99
