怎么把数据进行分组

[buzhunmeiyouni]

protected override string CreatePrintContent(params object[] printObject)
{
Member member = printObject[0] as Member;
List<MemberPassticket> remainPasstickets = (List<MemberPassticket>)printObject[1];

StringBuilder content = new StringBuilder();
content.Append(PrintBase.StringNewLine);
content.Append(PrintBase.StringNewLine);
content.Append(R.Text(R.Info_DecutedToday));
content.Append(PrintBase.StringSplitAndNewLine);
content.Append(PrintBase.StringNewLine);

//remainPasstickets = EntityBase.Search<MemberPassticket>()
// .GroupBy(x => x.PassticketId)
// .Select(x => new { a = x.Count(y => y.Passticket.PassticketName) }).ToList();

foreach (MemberPassticket memberPassticket in remainPasstickets)
{
content.Append(string.Format(R.Text(R.Info_ContentLaveInfo), memberPassticket.Passticket.PassticketName, memberPassticket.RemainAmount));
content.Append(PrintBase.StringNewLine);
}
content.Append(PrintBase.StringNewLine);
content.Append(PrintBase.StringNewLine);
content.Append(PrintBase.StringNewLine);
content.Append(PrintBase.StringNewLine);
content.Append(PrintBase.StringNewLine);
return content.ToString();
}


remainPasstickets 有多条数据，怎么把多条数据进行分组，注释部分是我写的分组，但是报错，string不能转换为bool

你得把需求说清楚 只说分组没人会回答的

照顾照看 look after 分组group by

你需要了解一下linq

是这样子的吗：

static void Main(string[] args)
{
    var data = new List<EquipParams>();

    data.Add(new EquipParams()
    {
        EquipName = "八阵图",
        EquipType = 1,
        EquipAttr = "攻击力+420，所有属性+350",
        EquipPrice = 11000
    });
    data.Add(new EquipParams()
    {
        EquipName = "诸神黄昏",
        EquipType = 1,
        EquipAttr = "攻击力+450，护甲+100，所有属性+150",
        EquipPrice = 162
    });
    data.Add(new EquipParams()
    {
        EquipName = "末日浩劫",
        EquipType = 2,
        EquipAttr = "所有属性+150，移动240",
        EquipPrice = 162
    });

    //获取类别为1的武器总量和总价格
    var result = data.GroupBy(x => x.EquipType).Select(g => new
    {
        type = g.Key,
        count = g.Count(),
        price = g.Sum(x => x.EquipPrice)
    });

    Console.WriteLine(JsonConvert.SerializeObject(result));
    Console.Read();
}

执行结果：
