I tried this code once without any exceptions. But now when i do it again in the same way i did it once i get this Exception saying,
The model item passed into the dictionary is of type 'System.Linq.Enumerable+WhereListIterator`1[myapp12.Models.Customer]', but this dictionary requires a model item of type 'myapp12.Models.Customer'.
This is my Code
CustomerController
**public class CustomerController : Controller
{
//
// GET: /Customer/
List<Customer> CustomerCollection = new List<Customer>();
public CustomerController()
{
Customer cus = new Customer();
cus.CustomerId = 1;
cus.Name = "Mags";
cus.Gender = "Male";
cus.City = "jerks";
CustomerCollection.Add(cus);
cus = new Customer();
cus.CustomerId = 2;
cus.Name = "Jacob";
cus.Gender = "Male";
cus.City = "Wagga";
CustomerCollection.Add(cus);
cus = new Customer();
cus.CustomerId = 3;
cus.Name = "Gags";
cus.Gender = "Male";
cus.City = "NewYork";
CustomerCollection.Add(cus);
}
public ActionResult GetCustomerList()
{
return View(CustomerCollection);
}
public ActionResult GetCustomer(int id)
{
var selectedCustomer = CustomerCollection.Where(p => p.CustomerId == id);
return View(selectedCustomer);
}**

this worked for me first time when i was doing first time. but now not working? wht should i do?
You have
var selectedCustomer =
CustomerCollection.Where(p => p.CustomerId == id);
where you should have
var selectedCustomer =
CustomerCollection.Where(p => p.CustomerId == id).FirstOrDefault();
Without getting the first element of the list you are actually passing an enumerable list instead of a single item.
