MVC route Query, what is the role of routing??

The Query method in model

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingsystem.web;namespacemvcapplication Routing contact. models{ Public classCARBF {PrivateMastercardatacontext _context =NewMastercardatacontext ();  PublicList<car>Select () {return_context.car.tolist (); }             PublicList<car> Selectbybrand (stringBrandcode) {                varQuery=_context.car.where (p=>p.brand==Brandcode); returnquery.            ToList (); }             PublicList<car> Selecbyprice (decimalLowdecimalupp) {                varquery = _context.car.where (P=>p.price>=low &&p.price<=upp); returnquery.            ToList (); }    }}

The code in the controller

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingsystem.web;usingSYSTEM.WEB.MVC;usingmvcapplication routing contact. Models;namespacemvcapplication Routing contact. controllers{ Public classHomecontroller:controller {//        //GET:/home/         PublicActionResult Index () {returnView (); }         PublicActionResult Findbyprice (decimalLowdecimalupp) {List<Car> list =NewCARBF ().            Selecbyprice (Low,upp); returnView (list); }    }}

Two views of the code

@{Layout=NULL;}<! DOCTYPE html>"Viewport"Content="Width=device-width"/> <title>Index</title>@using (Html.BeginForm ("Findbyprice","Home", FormMethod.Post)) {            <div>highest Price: @Html. TextBox (" Low"); Lowest Price: @Html. TextBox ("upp"); </div> <input id="Submit1"Type="Submit"Value="Enquiry"/>        }    </div></body>@using mvcapplication routing contact. Controllers; @using mvcapplication routing contact. Models; @model List<Car>@{Layout=NULL;}<! DOCTYPE html>"Viewport"Content="Width=device-width"/> <title>Findbyprice</title>@foreach (Car datainchModel) {            <li>@[email protected]</li>             }        </ol> </div></body>
