Stored procedures with ef 6 and code first - entity-framework

Question

I am quite new to EF and MVC. But I have managed to create scaffolded pages with MCV5 and views.
I understand there is difference in concept between webforms and EF. But is it possible for me to execute a stored procedure that is created in SSMS.
I want the ability of have a webpage with two text boxes that take in the two in parameters the stored procedure requires, both of the parameters being strings and then display the result in a webgrid.
Is this doable with EF code first and MVC?
The code for my stored procedure is:
CREATE PROCEDURE [dbo].[sp_FindRoutes]
#DepCity nvarchar(max),
#ArvCity nvarchar(max)
AS
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT dbo.Airlines.AirlineName, dbo.Routes.DepCity, dbo.Routes.ArvCity, dbo.Routes.FlightNr, dbo.AirlineRoutes.Fare, dbo.AirlineRoutes.AircraftAllocated
FROM dbo.Routes INNER JOIN
dbo.AirlineRoutes ON dbo.Routes.RouteId = dbo.AirlineRoutes.RouteId INNER JOIN
dbo.Airlines ON dbo.AirlineRoutes.AirlineId = dbo.Airlines.AirlineId
WHERE dbo.Routes.DepCity LIKE #DepCity AND dbo.Routes.ArvCity LIKE #ArvCity;
GO

Let's say your SP is like this (Just a simple version of your SP).
CREATE PROCEDURE [dbo].[sp_FindRoutes]
#DepCity string
AS
BEGIN
SET NOCOUNT ON;
SELECT dbo.Airlines.AirlineName, dbo.Routes.DepCity, dbo.Routes.ArvCity
FROM dbo.Routes
WHERE dbo.Routes.DepCity= #DepCity
END
You have to create an object that has the same property names as the results returned by the stored procedure.It's like this.
public class RouteForAirline
{
public string AirlineName { get; set; }
public string DepCity { get; set; }
public string ArvCity { get; set; }
}
Then call your SP as shown below.
Note : You can put this on the class file if you can access the DatabaseContext().
using(var context = new DatabaseContext())
{
var depCityParameter = new SqlParameter("#DepCity", "colombo");
var arvCityParameter = new SqlParameter("#ArvCity", "matara");
var results = context.Database.SqlQuery<RouteForAirline>("sp_FindRoutes #DepCity, #ArvCity",depCityParameter,arvCityParameter).ToList();
}
