解决C#中Linq GroupBy 和OrderBy失效的方法

CultureInfo culture = CultureInfo.GetCultureInfo("zh-cn");      List<TeamDto> teamDtos = teams          .GroupBy(x => new          {            x.TestId,            x.TestName          })          .Select(g => new TeamDto()          {            TestID = g.Key.TestId,            Test = g.Key.TestName,            Teams = g.ToList()          })          .OrderBy(t=>t.Test,StringComparer.Create(culture,true))          .ToList();
