我的应用程序中使用了以下类型的URL.
localhost/admin/userdetail/id
localhost/admin/userdetail/id/true
localhost/admin/userdetail/id/true/success
这是我的管理员控制器
bool inSaveAction,string status are optional
[Authorize]
public ActionResult UserDetail(string Id,bool inSaveAction,string status)
{
}
[HttpPost,Authorize,ValidateAntiForgeryToken]
public ActionResult SaveUserDetail(UserDetailviewmodel viewmodel)
{
User userToSave = new User();
AdminService.UpdateUser(userToSave);
//This is calling the above function as it sending all 3 params
return RedirectToAction("UserDetail",new { Id = viewmodel.Id,inSaveAction = true,status = "success" });
}
Below case is not working
@Html.ActionLink("DisplayName","UserDetail",new { id = Model.Id })
在Global.asax中
routes.MapRoute("UserDetail","UserDetail/{id}",new
{
controller = "Admin",action = "UserDetail",id = UrlParameter.Optional
}
);
我如何制作inSaveAction& status作为UserDetail操作的可选参数？
解决方法
您错过了路线配置中的参数.为了使这个工作具有可选的不同参数(如在Phil Haack的帖子中),您需要定义多个路径
routes.MapRoute("UserDetail-WithStatus","UserDetail/{id}/{inSaveAction}/{status}",new
{
controller = "Admin",// nothing optional
}
);
routes.MapRoute("UserDetail-WithoutStatus","UserDetail/{id}/{inSaveAction}",// nothing optional
}
);
routes.MapRoute("UserDetail-WithoutSaveAction",id = UrlParameter.Optional
}
);
然后创建链接：
@Html.ActionLink("Link","Index","Admin",new { id = 1,success = "success" },null)
您还需要将可选参数设置为可空,否则如果缺少id或inSaveAction,您将获得异常.
public ActionResult UserDetail(int? id,bool? inSaveAction,string status)
{
}
