如何将属性从剃刀页面模型传递给 asp-route-id 标签助手

Question

所以我正在使用 asp.net razor 页面，我想从我的一个页面模型中传递一个属性以用于 asp-route-id 标签助手_layout 页面。我尝试将特定页面模型注入 _layout 页面并通过 @Model 标记访问它，当我使用它并将鼠标悬停在导航栏上时，我想显示的路线 ID 出现了，但是当我点击它时我得到了这个错误:

如果我使用 viewdata，它会在单击导航项后消失并变为空。

_layout.cshtml（共享）

@model VescovererWebApp.Pages.AccountModel

Answer 1

尝试使用 AccountModel 作为基础 class

public class VescoveredModel : AccountModel

或者您可以创建接口 IAccountModel

public class AccountModel:IAccountModel

和

public class VescoveredModel : IAccountModel

并更改布局模型

@model VescovererWebApp.Pages.IAccountModel
