c# - Pass array to a view using query string MVC -

i have multiple roles , need pass roles view via return redirectto action method,

my code

string[] roles = new string[] { "admin", "supervisor", "interviewer" }; if (roles.count() > 1) {     return redirecttoaction("loginas","admin",new{@roles = roles}); } 

when pass in loginas view shows me url this,

http://localhost:33883/admin/loginas?roles=system.string[] 

but there's no passed values.

option 1 :

    public actionresult index()     {         string[] roles = new string[] { "admin", "supervisor", "interviewer" };         var routeparameters = new routevaluedictionary();         (int = 0; < roles.length; i++)         {             routeparameters["roles[" + + "]"] = roles[i];         }         return redirecttoaction("test", "student", routeparameters);     }      public actionresult test(string[] roles)     {         return view("index");     } 

output -

option 2: use tempdata
