xUnit converting IDictionary to IEnumerable

Question

I've been searching the web for a way to make an IEnumerable in the Setup of a Mock by converting the Values of my IDictionary to it (either directly or conversion from '=List to IEnumerable). However I have only come across the latter.

Inspiration Sources:

1. IEnumerable<object> a = new IEnumerable<object>(); Can i do this?
2. Convert dictionary with List to IEnumerable
3. Convert dictionary of any type to IEnumerable collection

4. How to use Moq to return a List of data or values?

   public class UserServiceTests
   {
       private Mock<IUserRepository> _userRep { get; set; }
   
       // fake app repository to get data from
       private IDictionary<int, User> _userRepData { get; set; }
   
       private UserService _sut { get; set; }
   
       public UserServiceTests()
   {
       _userRepData = new Dictionary<int, User>();
   
       _userRep = new Mock<IUserRepository>();
   
       // Been able to create the proper list using:
       // List<User> usersList = _userRepData.Values.ToList<User>(); 
       // IEnumerable<User> users = appsList.AsEnumerable();
       // So I am looking for away to replicate this in my setup method
       // Obviously know the below is not the correct syntax.
       _userRep.Setup(r => r.GetUsers()).Returns(() => new IEnumerable<User> {_userRepData.Values.ToList<User>} );
   
       _sut = new UserService(_userRep.Object);
   }
   
   [Fact]
   public void GetUsers_succeeds_at_getting_all_users_from_repository()
   {
       User user1 = new User();
       User user2 = new User();
   
       _userRepData.Add(1, user1);
       _userRepData.Add(2, user2);
   
       IEnumerable<User> users = new User[] { user1, user2 };
   
       _sut.GetUsers().Should().BeSameAs(users); // Note: fluentassertions
   }
   

   }

Answer 1

Values already implements IEnumerable<T>.
You can return it directly; you don't need to create anything.
