Hi @Trott, Dwayne

How do I access secrets.json from any class? I have a .NET Core API project. I can access the values in Program.cs, but I want to be able to read from other classes e.g. Respository class.

You can use JSON configuration provider to load the secrets.json file, then access the value via IConfiguration.

Refer to the following sample:

1.Add a secrets.json file:

2.Load the secrets.json file in the program.cs file:

//load the json file.
builder.Configuration.AddJsonFile("secrets.json",
        optional: true,
        reloadOnChange: true);
//register the service 
builder.Services.AddScoped<IDataRepository, DataRepository>();

//get the value from the secrets.json file
var name = builder.Configuration.GetSection("Employee:name").Value;

3.The DataRepository service like this:

    public interface IDataRepository
    {
        string GetEmployeeName();
    }
    public class DataRepository : IDataRepository
    {
        public IConfiguration _config;
        public DataRepository(IConfiguration configuration)
        {
            _config=configuration;
        }
         
        public string GetEmployeeName()
        {
            return _config.GetSection("Employee:name").Value;
        }
    }

After that, in the API controller, we can inject the service and then get the value.

    [Route("api/[controller]")]
    [ApiController]
    public class EmployeeController : ControllerBase
    {
        private readonly IDataRepository _datarepo;

        public EmployeeController(IDataRepository dataRepository)
        {
            _datarepo=dataRepository;
        }
        public string Get()
        {
            return _datarepo.GetEmployeeName();
        }
    }
