Question

This is the method in my Model :

 public IList<Customer> GetProfileCustomer(int id)
    {
        var list_customer = from c in DataContext.Customers
                            where c.ID == id
                            select c;
        return list_customer.ToList();
    }

And this is what I did in my controller :

   public ActionResult ShowProfile()
    {
        List<CustomerModels> cus = new List<CustomerModels>();

        return View();
    }

I created the object cus to call the method GetProfileCustomer() in the model, but I cannot do that. When I write : cus.GetProfileCustomer, It is error.

Your major issue is the line:

List<CustomerModels> cus = new List<CustomerModels>();

That is not creating an instance of CustomerModels, so you can’t call that method on it. You would have to do something like:

public ActionResult ShowProfile()
{
    cus = new CustomerModels();
    var data = cus.GetProfileCustomer(123);
    return View(data);
}

However, in the MVC sense, I don’t think loading data from your Model is really the right approach. Typically the Controller has some reference to something else that loads and saves data. The Model is usually just a class with properties to hold the data.

I would look at the “NerdDinner” sample project. For example, in these files:

• DinnersController.cs (controller)
• Dinner.cs (model)

Note that DinnersController holds a reference to a dinner repository, which is the thing that queries the database.
