推荐答案

有效！

ViewModel

ViewModel

public IEnumerable<SelectListItem> Sites {get; set;}
public string SiteSelected {get; set;}

控制器

private IEnumerable<SelectListItem> GetAllSites()
{
    return context.SITE.Select(x => new SelectListItem
    {
        Text = x.NAME,
        Value = SqlFunctions.StringConvert((double)x.ID).Trim()
    }).ToList();
}

siteViewModel.Sites = GetAllSites();

查看

@Html.DropDownListFor(model => model.SiteSelected , Model.Sites)
