c# - Handle Multiple action with same name in MVC -

in project there action

public actionresult lead(int leadid) {     return view(); } 

and in view actionlink created this

@html.actionlink("old link", "lead", "home", new { leadid = 7 }, null) 

but after time, make clean url, have changed name of parameter of action

public actionresult lead(int id) {     return view(); } 

and actionlink change accordingly

@html.actionlink("new link", "lead", "home", new { id = 5 }, null) 

but old link shared in multiple social network sites. whenever clicks on old link, redirect page www.xyx.com/home/lead?leadid=7

but in application, no such url exists.

to handle problem, thinking of overloading, mvc action doesn't support overloading.

i have created action same name parameter, , redirect new action, doesn't work.

public actionresult lead(int leadid, int extra=0) {     return redirecttoaction("lead", "home", new { id = leadid }); } 

i have found 1 link handle such situation, not working in case.

asp.net mvc ambiguous action methods

one possibility handle write custom route:

public class myroute : route {     public myroute() : base(         "home/lead/{id}",         new routevaluedictionary(new         {             controller = "home",             action = "lead",             id = urlparameter.optional,         }),         new mvcroutehandler()     )     {     }      public override routedata getroutedata(httpcontextbase httpcontext)     {         var rd = base.getroutedata(httpcontext);         if (rd == null)         {             return null;         }          var leadid = httpcontext.request.querystring["leadid"];         if (!string.isnullorempty(leadid))         {             rd.values["id"] = leadid;         }          return rd;     } } 

that register before default one:

public static void registerroutes(routecollection routes) {     routes.ignoreroute("{resource}.axd/{*pathinfo}");      routes.add(new myroute());      routes.maproute(         name: "default",         url: "{controller}/{action}/{id}",         defaults: new { controller = "home", action = "index", id = urlparameter.optional }     ); } 

and have single action:

public actionresult lead(int id) {     return view(); } 

now both following urls work expected:

• www.xyx.com/home/lead/7
• www.xyx.com/home/lead?leadid=7
