c# 3.0 - Getting Error: return statement is missing in switch statement -

-

i thought switch case written correctly got error:

return statement missing in last bracket.

please find below code:

    public  string  geturl(string code )        {         switch (code)          {            case  "1":                return "#";           case "2":               return "#";           case "3":                return "#";           case "4":               return "#";           case "5":                return "#";           case "6":                return "#";           case "7":                return "#";           }      }

thanks in advance

what missing default case. string should function return if none of cases mentioned occur.

e.g. pass "unknown" method geturl.

so add default case , things should work fine.

the code should like

    public  string  geturl(string code )        {         switch (code)          {            case  "1":                return "#";           case "2":               return "#";           case "3":                return "#";           case "4":               return "#";           case "5":                return "#";           case "6":                return "#";           case "7":                return "#";           default:               return "unknown case occured!";          }      }

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
