如何在剃刀页面 C# 代码块中注入 appsettings.json 配置？

Question

我正在关注以下官方文档：https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-6.0#access-configuration-in-razor-pages

@Configuration["myKey"] 的这种实现非常适合不在 @{} 括号之间的代码，但是当我有一个代码块时它根本不起作用。

据我所知，文档没有提供任何代码示例...

我该如何解决这个问题？

代码当然在 Razor 页面 (.cshtml) 中。

我尝试删除 @ 并在没有 @ 的情况下输入相同的代码，但随后出现上下文错误...

P.S。如果重要的话，相关代码是 POCO。

P.P.S。我使用 @inject IConfiguration Configuration 在 Razor 页面顶部导入配置。

我的问题代码：

var website = new WebSite()
        {
    private string altName = Configuration["FrameworkData:PageTitle"] +" - " +Configuration["FrameworkData:Slogan"];
    AlternateName = altName,
....

我已经尝试在配置规范之前指定 IConfiguration 类型，但没有任何效果。

更新

我的起始代码中有问题的部分：

@using Microsoft.AspNetCore.Http;
@using Schema.NET;
@model projectname2.Areas.MyFeature.Pages.Shared._LayoutModel
@using Microsoft.Extensions.Configuration
@inject IConfiguration Configuration
@{  
}

    @{
        var website = new WebSite()
        {
            private string altName = "";
    string altName = $"{Configuration["FrameworkData:PageTitle"]} - {Configuration["FrameworkData:Slogan"]}";
    AlternateName = altName,
    Name = Configuration["FrameworkData:PageTitle"],
    Url = new Uri("https://example.com")
};
        var jsonLd = website.ToString();
        var address = new PostalAddress()
        {
        StreetAddress = "Example street 10",
        AddressLocality = "NY",
        PostalCode = "11111",
        AddressCountry = "US"
        };
        var geo = new GeoCoordinates()
        {
            Latitude = 0.3947623,
            Longitude = 0.8723408
        };
        var localbusiness = new LocalBusiness()
            {
                Name = "Project name",
                Image = new Uri("https://example.com/graphics/logo.svg"),
                Url = new Uri("https://example.com"),
                Telephone = "1234 1243567",
                Address = address,
                Geo = geo,
                SameAs = new Uri("https://example.com"),

            };
        
        var jsonLdlb = localbusiness.ToString();
        var organization = new Organization()
            {
                AreaServed = "US",
                ContactPoint = new ContactPoint()
                {
                    AvailableLanguage = "English",
                    ContactOption = ContactPointOption.TollFree,
                    ContactType = "customer service",
                    Telephone = "1234 1243567"
                },
                Url = new Uri("https://example.com"),

            };
            var jsonLdorg = organization.ToString();
    }

Answer 1

@using Microsoft.Extensions.Configuration
@inject IConfiguration Configuration
@{
   string myValue = Configuration["FrameworkData:PageTitle"];
   // Do your things
}

Refer Microsoft Docs

Answer 2

我不得不在另一个代码块中定义有问题的代码块之外的变量，如下所示：

@{
    var pageTitle = Configuration["FrameworkData:PageTitle"];
}

我必须在初始化 WebSite() 实例之前定义 altName：

var altName = $"{pageTitle} - {slogan}";
var website = new WebSite()

然后我就可以通过变量名引用变量了。

案件结案。
