How do you inject your appsettings.json configuration in a razor page C# code block?
Question
I was following the following official documentation: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-6.0#access-configuration-in-razor-pages
This implementation of @Configuration["myKey"] works perfectly for code that is not in between @{} brackets, but when I have a code block it simply does not work.
The documentation provides no code examples as far as I can see...
How do I solve this problem?
The code is of course in a Razor page (.cshtml).
I tried removing the @ and putting in the same code without the @ , but then it gives a context error...
PS the code in question is a POCO if it matters.
PPS I use @inject IConfiguration Configuration for importing the configuration at the top of the Razor page.
My problematic code:
var website = new WebSite()
{
private string altName = Configuration["FrameworkData:PageTitle"] +" - " +Configuration["FrameworkData:Slogan"];
AlternateName = altName,
....
I've already tried specifying the IConfiguration Type before the Configuration specification without any avail.
UPDATE
My starting code with the problematic parts in it:
@using Microsoft.AspNetCore.Http;
@using Schema.NET;
@model projectname2.Areas.MyFeature.Pages.Shared._LayoutModel
@using Microsoft.Extensions.Configuration
@inject IConfiguration Configuration
@{
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta name='description' content='@ViewData["Description"]'>
<title>@ViewData["Title"] - @Configuration["FrameworkData:PageTitle"]</title>
@{
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"),
OpeningHours = "Mo-Fr 08:00-17:00",
};
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"),
Logo = new Uri("https://example.com/graphics/logo.svg"),
};
var jsonLdorg = organization.ToString();
}
<script type="application/ld+json">
@Html.Raw(jsonLd)
</script>
<script type="application/ld+json">
@Html.Raw(jsonLdlb)
</script>
<script type="application/ld+json">
@Html.Raw(jsonLdorg)
</script>

I had to define the variables outside of the problematic code block in an another code block like this:
@{
var pageTitle = Configuration["FrameworkData:PageTitle"];
}
I had to define the altName before initializing the WebSite() instance:
var altName = $"{pageTitle} - {slogan}";
var website = new WebSite()
And then I can just reference the variable by variable name.
