MapRoute

MapRoute is an extension method to add a route to IRouteBuilder with a specified name and template. A DefaultHandler needs to be added for route handling.

The following code shows how to define defaultHandler to be used with MapRoute:

    var routeHandler = new RouteHandler(context =>  
    { 
      var data = context.GetRouteData().Values; 
      return context.Response.WriteAsync("Controller Name is " +        data["controller"].ToString()); 
    }); 
     var routes = new RouteBuilder(app, routeHandler) 
    .MapRoute("packt", "{controller}/{action}") 
    .Build(); 
    app.UseRouter(routes);
