Binding options inside other options services.Configure<>()

Imagine I have the following settings in appsettings.json :

  {
  "OtherSettings" : {
    "id" : 3
  },
  
  "Needed" : {
    "Database" : {
      "ConnectionString" : "abc123"
    },

    "Interval" : {
      "is_active" = true,
      "in_seconds" = "15" 
    }
  } 
}

For the Database section I’ve got an class which is DatabaseSettings with property ConnectionString.

And for the Interval section I’ve got the class IntervalSettings.

If I would like to bind all those settings inside Needed to an class NeededSettings, what property do I need and how would I bind the options for the Database class with Dependency Injection ? Currently I am doing this with:

services.Configure<DatabaseSettings>Configuration.GetSection("Needed:Database"));
services.Configure<IntervalSettings>(Configuration.GetSection("Needed:Interval"));

So I am doing this with 2 lines, but I want to do it in 1 line and bind all the settings to the new class NeededSettings

>Solution :

Simply remove these two lines and add:

services.Configure<NeededSettings>(Configuration.GetSection("Needed"));

and use NeededSettings in all places you used DatabaseSettings and IntervalSetttings.

Edit:

public class NeededSettings{
    public DatabaseSettings Database {get;set;}
    public IntervalSettings Interval {get;set;}
}
