OptionsExtensions

OptionsExtensions.GetOptionsTypes(services) searches for all IConfigureOptions<>, IOptions<>, IOptionsMonitor<>, IOptionsSnapshot<>, IOptionsChangeTokenSource<> option types.

// Key-Values
Dictionary<string, string?> map = new Dictionary<string, string?>
{
    { "Car:License", "XYZ-123" }
};
// Create configuration
IConfigurationRoot configuration = new ConfigurationBuilder()
    .AddInMemoryCollection(map)
    .Build();
// Create dependency injection
IServiceCollection serviceCollection = new ServiceCollection();
serviceCollection.AddSingleton<IServiceCollection>(serviceCollection);
serviceCollection
    .AddSingleton<IConfiguration>(configuration)
    .AddOptions<Car>().BindConfiguration("Car");
IServiceProvider services = serviceCollection.BuildServiceProvider();
// Acquire car
IOptions<Car> carInfo = services.GetService<IOptions<Car>>()!;
WriteLine(carInfo.Value.License); // "XYZ-123"
// Get IConfigureOptions<>, IOptions<>, IOptionsMonitor<>, IOptionsSnapshot<>, IOptionsChangeTokenSource<>
foreach (Type optionsType in OptionsExtensions.GetOptionsTypes(services))
    WriteLine(optionsType); // Car

public record Car
{
    public string License { get; set; } = null!;
}
