How to compare the data in sqlServer using WCF with MVC ?!!

Question

 i can't read from database then compare this string with the parameter of certain function

i'm using ASP.net MVC4 

i tried that i create WCF as following :

 

public int login_service (string username, string password)

{

OnlineFoodOrderingEntities user1 = new OnlineFoodOrderingEntities();

var x = from n in user1.users select n;

List tst= x.ToList();

if (tst[0].username == username && tst[0].password == password )

{

return 1;

}

else{ 

return 0;

}

 }

then in MVC application 

 

public ActionResult Login(string username, string password)

{

ServiceReference1.ServiceClient sc = new ServiceReference1.ServiceClient();

int check = sc.login_service(username,password);

if ( check == 1)

{

return RedirectToAction("cuisine", "Home");

}

else

{

return View();

}

} 

 

the database is called OnlineFoodOrdering 

and the table is called user 

i want when the check variable is equle to "1" it redirect to Home/cuisine.

please any help
