How to extract a list from appsettings.json in .net core

Question

I have an appsettings.json file which looks like this:

{
    \"someSetting\": {
        \"subSettings\": [
            \"one\",
            \"two\",
                 


        

Answer 1

In my case configuration

 services.Configure>(Configuration.GetSection("ApiKeysList"));

wasn't loaded because the properties were read-only and there were no default constructor

 **//not working** 
  public class ApiKey : IApiKey
    {
        public ApiKey(string key, string owner)
        {
            Key = key;
            OwnerName = owner;
        }
        public string Key { get;  }
        public string OwnerName { get;}
    } 

//Working

    public class ApiKey : IApiKey
    {
        public ApiKey(){}//Added default constructor
        public ApiKey(string key, string owner)
        {
            Key = key;
            OwnerName = owner;
        }
        public string Key { get; set; }        //Added set property
        public string OwnerName { get; set; }  //Added set property
    }
