签名中的匿名类型

我试图让下面的方法签名工作.因为这是一个匿名类型我有一些麻烦,任何帮助都会很棒.

当我在QuickWatch窗口中查看sortedGameList.ToList()时,我得到了签名

System.Collections.Generic.List<<>f__AnonymousType0>>

非常感谢

唐纳德

   public List> getGamesList(int leagueID)
{
    var sortedGameList =
        from g in Games
        group g by g.Date into s
        select new { Date = s.Key, Games = s };

    return sortedGameList.ToList();

}

选择新的{Date = s.Key,Games = s.ToList()};

编辑:那错了!我认为这样做.

public List> getGamesList(int leagueID)
{
    var sortedGameList =
        from g in Games
        group g by g.Date;

    return sortedGameList.ToList();
}

不,你不需要选择!

选择新的{Date = s.Key,Games = s.ToList()};

public List> getGamesList(int leagueID)
{
    var sortedGameList =
        from g in Games
        group g by g.Date;

    return sortedGameList.ToList();
}

您不应该返回匿名实例.

您无法返回匿名类型.

创建一个类型(命名)并返回:

public class GameGroup
{
  public DateTime TheDate {get;set;}
  public List TheGames {get;set;}
}

//

public List getGamesGroups(int leagueID)
{
  List sortedGameList =
    Games
    .GroupBy(game => game.Date)
    .OrderBy(g => g.Key)
    .Select(g => new GameGroup(){TheDate = g.Key, TheGames = g.ToList()})
    .ToList();

  return sortedGameList;
}
