    How to read settings from appsettings.json in a view?

    Hi forum,

    I have Googled and tried (with only errors), so now I ask here. :)

    In a view I want to read some values from appsettings.json. I have found some code that seems to be part of the solution:

    MrAppsettings.cs:

    using Microsoft.Extensions.Options;
using Umbraco.Cms.Core.Configuration.Models;

namespace MrAppsettings
{
    public class SomeClass
    {
        private GlobalSettings _globalSettings;

        public SomeClass(IOptions<GlobalSettings> globalSettings)
        {
            _globalSettings = globalSettings.Value;

            var smtpHost = _globalSettings.Smtp.Host;
        }
    }
}

    1) As I can read this must be registered in Startup.cs, but how?

    2) And how do I "call" the class in my cshtml views?

    What you're doing here is DI. This is (a small) part of the solution.

    Example:

    Your appsettings.json:

    "EmailSettings": {
  "MailServer": "",
  "MailPort": ,
  "Email": "",
  "Password": "",
  "SenderName": "",
  "Sender": "",
  "SysAdminEmail": ""
},

    Register the service (so you can do DI) in startup.cs:

    services.Configure<EmailSettings>(configuration.GetSection("EmailSettings"));

    Settings Class:

    public class EmailSettings
{
  public string MailServer { get; set; }
  public int MailPort { get; set; }
  public string SenderName { get; set; }
  public string Sender { get; set; }
  public string Email { get; set; }
  public string Password { get; set; }
  public string SysAdminEmail { get; set; }
}

    Class, constructor and usage:

    private readonly IOptions<EmailSettings> _emailSettings;

public EmailSender(IOptions<EmailSettings> emailSettings)
{
  _emailSettings = emailSettings;
}

email.From.Add(new MailboxAddress(_emailSettings.Value.SenderName, _emailSetting.Value.Sender));

    Just to update this, personally I would inject a service. Look at @inject directive, creating a helper class that reads from the appSettings. This is referred to as "using dependency injection in a view" and you can read more about it in the Microsoft's Learn documentation.
