Drop down list with select list

Question

This is my select list from model.

public IEnumerable<SelectListItem> ServiceCycleList
{
    get
    {
        var Item = new List<SelectListItem>
        {
            new SelectListItem { Text = "Yearly", Value = "12" },
            new SelectListItem { Text = "Quarterly", Value = "3" },
            new SelectListItem { Text = "Monthly", Value = "1" }
        };
        return Item;
    }
}

I want to Create one dropdown list for this select list. How Can I to that?

Answer 1

如果模型视图可以使用它，则可以这样创建DropDownList ：

@Html.DropDownListFor(model => model.YourModelProperty, new SelectList(Model.ServiceCycleList, "Value", "Text"), "Please Select...")

Answer 2

Based on your comment above, your action method is returning a view without a model, and thus the error you get is the model is null.

public ActionResult Index(..)
{
   .
   .

   return View(); // missing model reference
}
