Question

我有做类似功能的动作链接。如何请求在控制器中单击哪个actionlink，以便我可以将它们全部放在相同的TopRated函数中，如下所示：

@Html.ActionLink("Today", "TopRated")
@Html.ActionLink("30 Days", "TopRated")
@Html.ActionLink("Weekly", "TopRated")
@Html.ActionLink("All Time", "TopRated")

而不是将它们放在4个不同的函数中：

@Html.ActionLink("Today", "Today")
@Html.ActionLink("30 Days", "TopRated30")
@Html.ActionLink("Weekly", "TopRatedWeekly")
@Html.ActionLink("All Time", "AllTimeTopRated")

控制器：

 public ActionResult TopRated()
        {
            using (var context = new EntityDBContext())
            {
                //Request which actionlink was just clicked by user
            }
        }

Answer 1

创建所有评分最高的时段的枚举器：

public enum PeriodEnum
{
   Today,
   ThirtyDays,
   Weekly,
   AllTime
}

您的TopRated应该会收到您之前创建的枚举类型的参数：

public ActionResult TopRated(PeriodEnum period)
{
    using (var context = new EntityDBContext())
    {
         //Request which actionlink was just clicked by user
    }
}

最后，您的操作链接将如下所示：

@Html.ActionLink("Today", "TopRated", new {period = PeriodEnum.Today})
@Html.ActionLink("30 Days", "TopRated", new {period = PeriodEnum.ThirtyDays})})
@Html.ActionLink("Weekly", "TopRated", new {period = PeriodEnum.Weekly})
@Html.ActionLink("All Time", "TopRated", new {period = PeriodEnum.AllTime})

在控制器中单击的MVC请求Actionlink
