Html.DropDownFor和所选项目的问题

Question

当SelectListItem Text与Value不同时，我无法使Html.DropDownFor正常工作。此问题是将特定项目标记为selected =“true”且一切都失败了！ （没有标记为selected =“true”）

public IEnumerable<SelectListItem> HaveFail {
        get {
            return
                IoC.Container.Resolve<Something>().GetAll().Select(
                    x =>
                    new SelectListItem {
                                           Text = x.Key,
                                           Value = x.Value.ToString(),
                                           Selected = (string.Compare(x.Key, myValue) == 0)
                                       });
        }
    }

public IEnumerable<SelectListItem> WorksFine {
        get {
            return
                IoC.Container.Resolve<Something>().GetAll().Select(
                    x =>
                    new SelectListItem {
                                           Text = x.Key,
                                           Value = x.Key,
                                           Selected = (string.Compare(x.Key, myValue) == 0)
                                       });
        }
    }

你已经倒退了。

new SelectListItem 
{
    Text = x.Value.ToString(),
    Value = x.Key,
    Selected = (string.Compare(x.Key, myValue) == 0)
}
