Whats the best way to return values in my Youtube Downloader .dll?

Question

So I'm basically making a youtube downloader .dll. What I need is to return two different types of values with their own values. I have tried writing these to a temporary file but this is resource consuming.

I need to return a collection of values called the youtube links I need to return a collection of values called the youtube link qualities I need to return a collection of values called the youtube link types

How should I do this? Dictionary?

Answer 1

How about just defining a custom class which describes the returned data?

public class YouTubeLink
{
   int Quality{get;private set;}
   string Type{get;private set;};
   string Url{get;private set;};
   public YouTubeLink(...){...}
}

public class YouTubeVideoInfo
{
   public ReadOnlyCollection<YouTubeLink> Links{get;}
   ...
}
