All of entities inherits BaseEntity class which has following properties:

• string Url
• DateTime Created
• DateTime Edited

So after you have an instance of one entity type, you can get his base properties:

Console.WriteLine(person.Created);

Examples

Using Repository<T> class:

IRepository<Starship> starshipRepo = new Repository<Starship>();
// The Starship class can be replaced with each other entity class: Person, Specie, Film, Vehicle or Planet.

The repository has two main methods for consume entities:

1. GetById(int id)

   If the entity with passed id doesn't exist, repository will return null.

   Starship starshipDetails = starshipRepo.GetById(3);
   
   // Allays check for null!!!
   if(starshipDetails != null)
   {
       Console.WriteLine(starship.Name);
   }
   
   // C# 6.0 syntax
   Console.WriteLine(starship?.Name);

   The Vehicle has collection of Films, but it's only URLs. So to access them you should manually done this:

   Vehicle vehicle = vehicleRepository.GetById(2);
   
   if (vehicle != null && vehicle.Films.Count > 0)
   {
       Console.WriteLine("Vehicle {0} has {1} films:", vehicle.Name, vehicle.Films.Count);
       foreach (var film in vehicle.Films)
       {
           // GetFilmId is a helper method just for extracting the id from the url. Example: https://swapi.dev/api/films/2/ - will return only 2.
           int filmId = this.GetFilmId(film);
       
           // getting related items should be done manual
           Film relatedFilm = filmRepository.GetById(filmId);
           Console.WriteLine(relatedFilm.Title);
       }
   }    

   Sometimes a property from entity can return unknown or n/a as a value. So be careful when parsing properties to other type. There are many ways to validate it:

   Specie specie = specieRepository.GetById(5);
   int SpecialSpan = 2;
   
   // Check for specie != null { ... }
   
   if (specie.AverageLifespan != "unknown")
   {
       int lifeSpan = int.Parse(specie.AverageLifespan);
       Console.WriteLine("Life span: " + (lifeSpan + SpecialSpan));
   }
   
   int lifeSpanAverage = 0;
   if (int.TryParse(specie.AverageLifespan, out lifeSpanAverage))
   {
       // If parse is success, lifeSpanAverage will have parsed value.
       Console.WriteLine("Life span: " + (lifeSpanAverage + SpecialSpan));
   }

2. GetEntities(int page = 1, int size = 10)

   By default size is from https://swapi.dev/api is 10. You can pass the page and size for getting entities, but you should know that if you want size 20 and page 3 it will start from 3-rd page and will collect entities from next pages until size is reached or next page is null. So all pages have 10 entities and with parameters above, the method will return entities on page 3 and 4.

   Example with first five entities from second page:

   var plnetsRepository = new Repository<Planet>();
   
   var planets = plnetsRepository.GetEntities(2, 5);
   
   if (planets == null)
   {
       Console.WriteLine("There are no planets on page {0}", page);
       return;
   }
   
   foreach (var planet in planets)
   {
       Console.WriteLine("Name: " + planet.Name);
       Console.WriteLine("Terrain: " + planet.Terrain);
   }

   If you call GetEntities without passing values, the method will return first ten entities from type in first page.

   To get all entities from type:

   var films = filmsRepo.GetEntities(size: int.MaxValue);    

3. Extending Entities:

   Make a class which inherits the entity type to extend for example person.

   public class MyPerson : Person
   {
       public override string ToString()
       {
           return this.Name + Environment.NewLine +
               "Birth year: " + this.BirthYear + Environment.NewLine +
               "Has " + this.Starships.Count + " starships"; 
       }
   }

   After that you can make a repository from MyPerson:

   IRepository<MyPerson> peopleRepo = new Repository<MyPerson>();
   MyPerson kenobi = peopleRepo.GetById(10);
   Console.WriteLine(kenobi.ToString());
   
   /***** Will print:
   
   Obi-Wan Kenobi
   Birth year: 57BBY
   Has 5 starships 
       */

All of the examples can be seen in the repository Example project.
