Viewbag属性里面的动作链接助手

Question

我试图在actionlink帮助器中包含和viewbag对象。

@Html.ActionLink( "Date" + ViewBag.icon , "Index", new{ sortBy=ViewBag.DateSort})

我的Viewbag的逻辑。

ViewBag.icon = (ViewBag.DateSort ==  "Date desc") ? "▼" :"▲";

我在这里实施排序。

Answer 1

只需将DateSort添加到Controller中的ViewBag，然后在View中执行此操作：

@{
  var dateHeader = "Date " + (ViewBag.DateSort ==  "Date desc" ? "▼" : "▲");
}

@Html.ActionLink(dateHeader, "Index", new { sortBy = ViewBag.DateSort })
