Routing issue in Asp.net MVC (404 Error)

Question

Hello People i have a list of Customers (with Name and Id) that i have hardcoded in my Customers Controller as: Click to view Customer Controller i am sending list to a view named Customer to display all the three customers with their names as links using following code :

@model IEnumerable<App.Models.Customer>
@{
    ViewBag.Title = "Customer";
}

@foreach (var customer in Model)
{
    <li>
        @Html.ActionLink(customer.Name, "Details", "Customers", new { id = customer.Id }, null)
    </li>
}

It displays list of customers but problem is when i click any customer name(Which is a link) it gives a HTTP 404 error as :Click to see Error details i have made a Details method in Costumers Controller as

[HttpPost]
public ActionResult Details(int id)
{
    var customer = GetCustomers().SingleOrDefault(x => x.Id == id);
    if (customer == null)
    {
        return HttpNotFound();
    }
    return View(customer);
}

that recieves id of the customer name being clicked and simply displays its name again but it doesnt works and gives 404 error i have debugged the code and what i have found that control never reached the details Method in Controller, is the issue in ActionLink or what ? Help is highly appreciated thank you

You cannot navigate to a POST method. Remove the [HttpPost] attribute from the Details() method — user3559349

The method should be HttpGet:

[HttpGet]
        public ActionResult Details(int id)
        {
            var customer = GetCustomers().SingleOrDefault(x => x.Id == id);
            if (customer == null)
            {
                return HttpNotFound();
            }
            return View(customer);
        }
