将 ViewBag 值从 ActionLink 传递到控制器
Passing ViewBag value from ActionLink to Controller
我正在尝试将 privApplicationId(从 ViewBag 检索)传递到控制器中的 ActionResult
布局 Cshtml 页面:
@Html.ActionLink("Comments", "ViewComments", "SubmittedApplications", new { @area = "Privileging" }, new { privApplicationId = @ViewBag.PrivApplicationId })
但是,每次进入 ActionResult 时,privApplicationId 值为 null。
控制器操作结果:
public ActionResult ViewComments(long? privApplicationId)
你能帮帮我吗?
您选择了错误的 ActionLink
助手重载。 new { privApplicationId = @ViewBag.PrivApplicationId }
作为 htmlAttribute
参数传递,但应该是 routeValue
。试试这个方法:
@Html.ActionLink("Comments", "ViewComments", "SubmittedApplications",
new { area = "Privileging", privApplicationId = @ViewBag.PrivApplicationId }, null)
从 ViewBag
中删除 @
并将 null 作为最后一个参数传递。
这应该有效
@Html.ActionLink("Comments",
"ViewComments",
"SubmittedApplications",
new
{
area = "Privileging",
privApplicationId = ViewBag.PrivApplicationId
},
null)
