Populating drop down list with hours of the day razor

Question

I am trying to populate the dropdown list with hours of the day using razor (mvc 5). I used one of the examples I found:

@Html.DropDownListFor(Model => Model.StartTime,
    Enumerable.Range(00, 24).Select(i => new SelectListItem { Value = i.ToString(), Text = i.ToString() }), "-- Hour --")

It shows the list, but as far as I understand since I used .ToString() it converted hours of the day (that I defined start time as integer in my model) to string and suppressed all leading zeros. What method I can use to display hours in 24 hour format, and let's say I want my default to show instead of literal Hour some hour of the day, For example 06.

It is new language for me, and learning as I go.

Answer 1

You can pad the string with leading zeros.

6.ToString("D2");
// Output: 06

For a default value: (Not have been tested)

@{ string defaultValue = string.IsNullOrEmpty(Model.StartTime) ? "06" : null; }
@Html.DropDownListFor
(
    Model =>
        Model.StartTime,
        Enumerable.Range(00, 24).Select(i => new SelectListItem { Value = i.ToString(), Text = i.ToString() }),
        "-- Hour --",
        defaultValue
)
