如何获取默认情况下要选择的值为0的SelectListItem之外的其他项?

我有一个 <select> 对于viewcomponent default.cshtml中的工作日,每天的关联值为0-6(星期日到星期六)。但是,我希望星期一列为第一天,因此在我的ViewModel中,我有:

public List<SelectListItem> SelectableWeekdays => new List<SelectListItem>
{
    new SelectListItem { Text = "Monday", Value = "1", Selected = true },
    new SelectListItem { Text = "Tuesday", Value = "2", Selected = false },
    new SelectListItem { Text = "Wednesday", Value = "3", Selected = false },
    new SelectListItem { Text = "Thursday", Value = "4", Selected = false },
    new SelectListItem { Text = "Friday", Value = "5", Selected = false },
    new SelectListItem { Text = "Saturday", Value = "6", Selected = false },
    new SelectListItem { Text = "Sunday", Value = "0", Selected = false }
};

在我的视图中,我呈现的下拉列表如下:

<select asp-for="Weekday" class="form-control" asp-items="@Model.SelectableWeekdays">
</select>

我还尝试手动添加选定的禁用选项:

<select asp-for="Weekday" class="form-control" asp-items="@Model.SelectableWeekdays">
    <option selected disabled>Please choose</option>
</select>

无论我尝试什么,所选选项始终是具有属性的“星期日” selected="selected" 为那天做准备。

我也试过增加

new SelectListItem { Text = "Please choose", Value = "99", Selected = true, Disabled = true },

在视图模型中,省略了视图中的手动选项,但这也不起作用。禁用的“请选择”-选项在列表的顶部,但星期日仍然是选定的选项。
