Question

I had a look at this:

ASP.NET MVC – How to pass an Array to the view?

and am struggeling with deploying my DateTime[] as a dropdownlist in the view, herewith my line but it is not correct:

<p style="color:Red"><%: Html.DropDownList("Choose a Sunday: ", (IEnumerable<SelectListItem>)ViewData["Sundays"], "--Select--")%>
</p>

In the controller i have:

[HttpGet]
public ActionResult MyAction()
{
  DateTime[] allSundaysInMonth = GetDatesOfSundays(System.DateTime.Now);
  ViewData["Sundays"] = allSundaysInMonth;
  return View();
}

can someone help please?
thanks

Answer 1

Perhaps what you want to do is this:

[HttpGet]
public ActionResult MyAction()
{
  IEnumerable<SelectListItem> allSundaysInMonth = GetDatesOfSundays(System.DateTime.Now).Select(day => new SelectListItem() { Text = day.ToString(), Value = day.ToString() });
  ViewData["Sundays"] = allSundaysInMonth;
  return View();
}

That is depending on your display format. What I’m trying to point out is that DateTime and SelectListItem may not have an implicit cast, so you get a type mismatch at runtime.
