❔ Method call based on config file

Based on a value in a config file, I want my program to call one of 3 methods who have different parameters but overall do the same thing. What's the best way to handle this? Overloading the method and adding an additional parameter?

Honestly, probably just a switch or if-else

So I would just rewrite this method for the other config values regularly and call them depending on which value is used?

Based on some value in the config file, you said?

Yes

switch (cfg.Whatever) {
    case "one":
        MethodOne(1, 2, "false");
        break;
    case "two":
        MethodTwo("hello", true, 9.19);
        break;
    case "three":
        MethodThree(new Person(), 67, 'a');
        break;
    default:
        throw new OutOfRangeException();
}

switch (cfg.Whatever) {
    case "one":
        MethodOne(1, 2, "false");
        break;
    case "two":
        MethodTwo("hello", true, 9.19);
        break;
    case "three":
        MethodThree(new Person(), 67, 'a');
        break;
    default:
        throw new OutOfRangeException();
}

Seems like a good approach I suppose, thanks

And you can use IOptionsMonitor to manage changes in config file during runtime

In case you need that, I was excited when first see this and use in my app https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/options?view=aspnetcore-7.0
