我正在尝试在netcore中实现干净的架构，但遇到运行时错误InvalidCastException：无法将"系统.集合.泛型.列表"类型的对象强制转换为"系统.集合.泛型. IEnumerable
在WebUI中，我有Match控制器和ViewAllMatch动作，如下所示

public async Task<IActionResult> ViewAllMatch()
        {
            var matches = await _mediator.Send(new GetMatchesDetail());
            return View(matches);
        }

在应用层，我有一个如下的查询：

public class GetMatchesDetail : IRequest<IEnumerable<MatchesDetail>>
    {
    }
    public class MatchesDetail
    {
        public string MatchId { get; set; }
        public int MatchNumer { get; set; }
        public DateTime DateMatch { get; set; }
        public TimeSpan TimeMatch { get; set; }
        public int MatchYear { get; set; }
        public string SeasonId { get; set; }
        public string Round { get; set; }
        /// <summary>
        /// Set value to Qualified for Qualified and Final for Final Round
        /// </summary>
        public string Stage { get; set; }
        public string SubStage { get; set; }
        public string HTeam { get; set; }
        public string HTeamCode { get; set; } //For Flag get from Table Team from Foreign Key TeamName
        public int HGoal { get; set; }
        public int GGoal { get; set; }
        public string GTeam { get; set; }
        public string GTeamCode { get; set; }
        public string WinNote { get; set; }
        public string Stadium { get; set; }
        public string Referee { get; set; }
        public long Visistors { get; set; }
        public string Status { get; set; }
    }

    public class GetMatchesHandler : IRequestHandler<GetMatchesDetail, IEnumerable<MatchesDetail>>
    {
        private readonly IMatchRepository _matchRepository;
       
        public GetMatchesHandler(IMatchRepository matchRepository)
        {
            _matchRepository = matchRepository;
        }

        public async Task<IEnumerable<MatchesDetail>> Handle(GetMatchesDetail request, CancellationToken cancellationToken)
        {
            var matchlistview = await _matchRepository.GetMatchDetailAsync();

            return matchlistview;
        }
    }

matchRepository获取基础设施中所有匹配项的代码，如下所示。

public async Task<IEnumerable<MatchesDetail>> GetMatchDetailAsync()
        {
            var matchDetailList = (from match in _context.Matches
                                   join team1 in _context.Teams on match.HTeam equals team1.TeamName
                                   join team2 in _context.Teams on match.GTeam equals team2.TeamName
                                   join season in _context.Seasons on match.SeasonId equals season.SeasonId
                                   select new
                                   {
                                       match.MatchId,
                                       match.MatchNumber,
                                       match.DateMatch,
                                       match.TimeMatch,
                                       match.MatchYear,
                                       match.SeasonId,
                                       season.SeasonName,
                                       match.Round,
                                       match.Stage,
                                       match.SubStage,
                                       match.HTeam,
                                       HTeamCode = team1.TeamCode,
                                       match.HGoal,
                                       match.GGoal,
                                       match.GTeam,
                                       GTeamCode = team2.TeamCode,
                                       match.WinNote,
                                       match.Stadium,
                                       match.Referee,
                                       match.Visistors

                                   });

            return (IEnumerable<MatchesDetail>)await matchDetailList.ToListAsync();
        }

谢谢你的帮助。当我有更多的实体和我想在WebUI中查看的模型包含域中的许多实体时，我对清洁建筑技术中的模型感到困惑。
