c# - How to set different routes for the same Controller method with different parameters? -

i have reportcontroller llooks this:

public iactionresult reportdetails(int? reportid){     .... } 

and

public iactionresult reportdetails(int? reportid, bool ? approved) {     .... } 

and tried routing, bu failed. actual code written in startup.cs:

app.usemvc(routes =>             {                 routes.maproute(                     name: "reportdetailsvalidation",                     template: "descriptionvalidation",                     defaults: new { controller = "report", action = "reportdetails", reportid ="{reportid}", approved = "{approved}" }                     );                  routes.maproute(                     name: "reportdetails",                     template: "description",                     defaults: new { controller = "report", action = "reportdetails"}                      );                  routes.maproute(                     name: "default",                     template: "{controller=home}/{action=index}/{id?}");             }); 

as have seen need match following url's:
/report/reportdetails?reportid=7 first and
/report/reportdetails?reportid=7&approved=true second

you can't that, have 2 methods identical name different parameters, because should ambiguousactionexception.

asp core action selector not care action's parameters during select action. therefore can't have 2 actions correspond 1 route template. workaround play action constraints (like httpget , httppost). can check on github. (see selectbestcandidate method)

theoretically if parameters matters logic choose between actions based on parameters should in selectbestactions method, ignores parameters.

in case option seems to have 1 method:

public iactionresult reportdetails(int? reportid, bool? approved) {     .... } 

and check if approved null (/report/reportdetails?reportid=7), implement 1st logic, otherwise(/report/reportdetails?reportid=7&approved=true) implement 2nd logic. if logic contains many lines can extract them in new method , call it.

public iactionresult reportdetails(int? reportid, bool? approved) {      if (approved != null)      {         //implement logic 2nd case(approved=true)      }      //implement logic 1st case (just reportid=7) }
