how can we show arraylist each value to dropdownlistfor?

Assuming that your Address class contains ID ,City ... attribute, the code below will explain to you how to bind DropDownList easily in Asp.NET MVC application.

1. In Model folder define the Address and Address Collection class,

public class Address{
    public int ID{get;set};
    public string City{get;set};
    // ...
}

public class Addresses:List<Address> {
    public Addresses() {
        this.Add(new Address() {ID=1, City="A"});
        this.Add(new Address() {ID=2, City="B"});
    }
}

2 In Contoller class that is going to consume the Address collection as follow.

public ActionResult Index()
{
    Addresses addresses = new Addresses();
    ViewBag.Addresses= new SelectList(addresses.AsEnumerable(), "ID","City");
    return View();
}

3. In the View page consume the ViewBag.Addresses values as follow.

@Html.DropDownList("address", (SelectList)ViewBag.Addresses, "All Addresses")
