Question

New to MVC3 Razor – linq to sql having spent some time trying to find how to:

Match the loged on UsersName to Customer.UserName and then select the Customer.CustomerID for the user.

public ViewResult Index()
    {
        var CustomerID = from c in Customer
            where c.UserName = "User.Identity.Name"
            select c.CustomerID;

        return View();
    }

Answer 1

Just use the actual variable:

public ActionResult Index()
    {
        var CustomerID = from c in Customer
            where c.UserName == User.Identity.Name  //use double equals for comparison
            select c.CustomerID;

        return View(CustomerID);  //or whatever your view is -- some typed object?
    }
