xUnit将字典转换为IEnumerable

我一直在网上搜索一种方法，通过将我的IDictionary的值转换为模拟的Setup来制作IEnumerable(直接或从'= List转换为IEnumerable)。然而，我只遇到了后者。

灵感来源:

1. IEnumerable
2. 将带列表的字典转换为IEnumerable
3. 将任意类型的字典转换为IEnumerable集合

4. 如何使用Moq返回数据或值的列表?

   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
   }
   

   }
