asp.net MVC routing rules and brief description __.net

All of the following custom routing rules must not be effective until the default routing rule

Direct method overload + anonymous Object

The most basic routing rule, and also the default routing rule
Routes. Maproute (
Name: "Default",
URL: ' {controller}/{action}/{id} ',
defaults:new {controller = "Home", action = "Index", id = urlparameter.optional}
);

Constructs a route and then adds
Route Myroute = new Route ("{controller}/{action}", New Mvcroutehandler ());
Routes. ADD ("MyRoute0", Myroute);

To add a route to a namespace

In the action, a parameter "catchall" is defined to receive all the parameter values in the URL except the ID

Catchall This will enable the transfer of multiple parameters

Routing across namespaces
Routes. Maproute (
"Addcontollerroute",
"Home/{action}/{id}/{*catchall}",
New {controller = "Home", action = "Index", id = urlparameter.optional},
New[] {"Urlsandroutes.additionalcontrollers"}
);
Routes. Maproute (
"MyRoute1",
' {Controller}/{action}/{id}/{*catchall} ',
New {controller = "Home", action = "Index", id = urlparameter.optional},
New[] {"Urlsandroutes.controllers"}
);

After adding {*catchall} to this configuration after {ID}, you need to increase the string catchall this parameter after the action's parameter ID to get all the parameters except the ID, as follows:

Public ActionResult abctest (string id,string catchall)
{
string temp = ID;
string tt = Catchall;

return Content (ID);
}

Variable-length routing + regular expression matching routing

//Regular expression, in routing configuration, we have made such a rule that only matches the controller name with H
             routes. Maproute (
               ) MyRoute2 ",
               " { Controller}/{action}/{id}/{*catchall} ",
                 New {controller = "Home", action = "Index", id = urlparameter.optional},
                 New {controller = "^h.*", action = "^index$| ^about$ "},
                new[] { "Urlsandroutes.controllers"}
           );

           //Specify Request methods
             routes. Maproute ("MyRoute3", "{Controller}/{action}/{id}/{*catchall}",
                 New {controller = "Home", action = "Index", id = urlparameter.optional} ,
                New {controller = "^h.*", action = "index| About ", HttpMethod = new Httpmethodconstraint (" Get ")},
                 new[] {"Urlsandroutes.controllers"}
            );
