Question

我有两门小组和运动员小组。

public class PlayerTeams
{
    public int ID { get; set; }
    public string PlayerName { get; set; }
    public string PlayerCountry { get; set; }
    public bool IsActive { get; set; }

    public string PlayerTeam { get; set; }
}

public class Players
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string Country { get; set; }
    public bool? Status { get; set; }
}

页: 1 运动员名称/编码,按<代码>PlayerTeam加以分类。

var groupedPlayers = teams
            .OrderBy(x => x.PlayerName)
            .GroupBy( x => x.PlayerTeam)
            .ToList();

其类型如下:<代码>List<IGrouping<string,sexualTeams>>,但我希望该代码为List<Igrouping<string, Hawaiis>>,因为我不想在每一行中提供多余的关键信息。

我如何能够做到这一点? 我只能想像<条码>。我也未能做到这一点。

是否有这样做的可信方法?

Answer 1

如果你能够改变分类,我只想:

var groupedPlayers = teams
            .OrderBy(x => x.PlayerName)
            .GroupBy(x => x.PlayerTeam, Players.FromPlayerTeam)
            .ToList();

<代码>Players.FromPlayerTeam为上的固定方法。运动员,采用<代码>PlayerTeam,并填写<编码>。

Additionally, I d suggest using ToLookup instead of GroupBy - a Lookup is exactly what you want here, without bothering with the ToList call.

Answer 2

www.un.org/Depts/DGACM/index_spanish.htm 这并不是说,只是一个想法。

如果你在转换你的林克声明方面遇到困难,预计这一发言将<代码>。 Igrouping, to a string list, it may have to select/strong>.

var groupedPlayers = new List<string>(); groupedPlayers = teams .OrderBy(x => x.PlayerName) .GroupBy(x => x.PlayerTeam, Players.FromPlayerTeam) .Select(x => x.Key) // << added select .ToList();
