IConfiguration - how to bind dynamic values from configuration to object-CodePudding

I am having configuration.ini file which contain following content ->

[Objects]
obj1={7CE7ECE0-B70D-4622-8F4B-D999E5F06AAD}
obj2={5964945B-C31B-4805-9408-D56A4A5457CF}
obj3={5964945B-C31B-4805-9408-D56A4A5457CF}

Those keys - objN can be dynamically added.

With help of ConfigurationBuilder I am creating the config ->

IConfigurationRoot configuration = new ConfigurationBuilder()
     .AddIniFile(Path.Combine(configFolderPath, @"Configuration.ini"))
     .Build();

Now when it come to the topic of Binding to object I get stuck and cant find any solution.


services.AddOptions<SomeObject>()
                .Bind(_configuration.GetSection("Object"))

P.S
As temporary solution I found is to get configuration section as enumerable which is dictionary<string,string> and then map it manually. This is just look quite dirty.

configuration.GetSection("Objects").AsEnumerable()

I would say Guru Stron gave you the answer.

services.Configure<Dictionary<string, Guid>>(_configuration.GetSection("Objects"));

Then, consume with DI:

public class SomeService
{
    private Dictionary<string, Guid> Objects { get; }
    public SomeService(IOptions<Dictionary<string,Guid>> objects)
    {
        Objects = objects.Value;
    }
}

If you feel that Dictionary<string,Guid> is not a specific-enough data type, simply create a derived class:

public class MyObjectDictionary : Dictionary<string, Guid>
{ }

Then use MyObjectDictionary as the type in the call to services.Configure<>().

You should look at using the INI configuration provider for this https://learn.microsoft.com/en-us/dotnet/core/extensions/configuration-providers#ini-configuration-provider

As for dynamic loading, You can use IOptionsSnapshot or IOptionsMonitor.

I think this would be working for you

    public class MyClass
    {
        private readonly Dictionary<string, string> _objects ;
        public MyClass(IConfiguration config)
        {
            _objects=config.GetSection("Objects").Get<Dictionary<string, string>>();
            Console.WriteLine(_objects["obj1"]);
        }
    }
