从 RazorPage 继承时出错<TModel>

Question

我想在 AspCore Razor Page 中使用本地化。

但是，我遇到了以下错误：

CS0108: 'Pages_Index.ViewData' hides inherited member 'RazorPage<IndexModel>.ViewData'. Use the new keyword if hiding was intended.

CS0108: 'Pages_Index.Model' hides inherited member 'RazorPage<IndexModel>.Model'. Use the new keyword if hiding was intended.

CS0103: The name 'PageContext' does not exist in the current context.

The type 'Pages_Index' is not a valid page. A page must inherit from 'Microsoft.AspNetCore.Mvc.RazorPages.PageBase'

我的代码如下：

public abstract class BaseViewPage<TModel> : RazorPage<TModel>  
{  
    [RazorInject]  
    public ILanguageService LanguageService { get; set; }  
    [RazorInject]  
    public ILocalizationService LocalizationService { get; set; }  
    public delegate HtmlString Localizer(string resourceKey, params object[] args);  
    private Localizer _localizer;  
    public Localizer Localize  
    {  
        get  
        {  
            //logic  
            
            return _localizer;  
        }  
    }  
}  

public abstract class CustomBaseViewPage : BaseViewPage<dynamic>  
{ }

我在

@inherits CustomBaseViewPage<TModel>

中使用

_ViewImports.cshtml

。

查看代码为：

@{  
    ViewData["Title"] = Localize("customer.page.create.title");  
}  
   
<div>  
     <h3>@Localize("customer.page.create.title")</h3>  
</div> 

Answer 1

首先，如果除了本地化之外没有更多关于

CustomBaseViewPage

的内容，那么这应该不是必需的，而是您应该在要本地化的每个视图中注入

IStringLocalizer

。

尽管如此，您也可以使用自定义基类，但必须删除所有页面中的

@page

指令，以免存在多个包含相同成员的基类。另外，您还必须处理路由，请参阅 https://learn.microsoft.com/en-us/aspnet/core/razor-pages/razor-pages-conventions?view=aspnetcore-8.0
