How to make WCF for Login function using ASP.NET MVC4

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();

foreach (var u in tst)

{

if (u.username == username && u.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

Hello Hadeer

Follow the steps.

loginclass.cs property in App_Code folder

public int userlogin(string username, string password)
{
var login =
(from tblreg in ME.USER_ADMIN_SIGNUP where tblreg.EMAIL_ID == username && tblreg.USER_PASSWORD == password
select tblreg).Count() > 0;
if(login)
{
return 1;
}
else
return 0;
}

in IService.cs interface

[OperationContract]
public class userlogin(string username,string password)

in Service.svc file:

public int userlogin(string username,string password)
{
loginclass lc = new loginclass();
lc.userlogin(username,password)
}

in MVC

[HttpGet]
public ActionResult Login()
{
return View();
}
[HttpPost]
public ActionResult Login(string username, string password)
{
servicereference.client ser = new servicereference.client;
int check = ser.userlogin(username,password);
if(check ==1)
{
return RedirectToAction("cuisine","Home")
}
else
return View()
}

ViewBag.Title = "Login";

}

@using (Html.BeginForm("Login", "Login", FormMethod.Post))

{

Mvc Simple Login Application Demo

@Html.AntiForgeryToken()

@Html.ValidationSummary(true)

@if (@ViewBag.Message != null)

{

@ViewBag.Message

}

@Html.Label("username")	@Html.TextBox("username")	@Html.ValidationMessage("username")
@Html.Label("password")	@Html.Password("password")	@Html.ValidationMessage("password")

}

Hope this will work for you.

Happy coding
