Hi, I am working on writing a web api in asp.net core and trying read values from appsettings.json "AppSettings" and get error "an object reference is required for the non-static field, method or property".

appsettings.json

{
    "AppSettings": {
        "User": "test",
        "Password": "0123abcd"
    }
}

Startup.cs

public IConfiguration Configuration { get; }

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
    services.AddSingleton<IConfiguration>(Configuration);
    services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));
}

What I have tried:

When I am trying to read the Username & Password appsettings.json in security class like below. I run into "an object reference is required for the non-static field, method or property".

public class security
{
    private AppSettings AppSettings { get; set; }

    public security(IOptions<AppSettings> settings)
    {
        AppSettings = settings.Value;
    }
    public static bool Login(string username, string password)
    {
        if (username == AppSettings.User && password == AppSettings.Password)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}
