Question

我正在尝试重新编号列表中的值，该列表将动态地传递给我。我已经进入了第三类叫做＃34;混合＆＃34;而且我不确定如何做到这一点。

＆＃34;混合＆＃34; category将有一个可能相同的palletno。如果该值是相同的，我需要它做的是增加1，我正在做但我需要该类别的起始值为tempPN值（在此列表中将为7）。我尝试了不同的方法，但这是我能得到的最接近的方法。任何的意见都将会有帮助。

public class Program
{
    public class PalletNumberRepository
{
    public class PalletNumber
{
        public int palletno { get; set; }
        public decimal weight { get; set; }
        public decimal totalwieght {get; set;}
        public string palletstatus {get; set;}
        public string dropno {get; set;}

}

    public List<PalletNumber> GetPalletNumbers()
    {
        return new List<PalletNumber>
        {
        new PalletNumber(){ palletno = 3, weight = 2575m, totalwieght = 3667m, palletstatus = "Mixed", dropno = "1B"},

                    // This is were I I need the tempPN 
                    //(7 in this run) to replace all the 4's 
                    //then step up to 8 for the 5's. So on and so on.

                    //the list is going to always be different

                    i.palletno += 1;
                    Console.WriteLine(i.palletno + " Pallet Status: " + i.palletstatus);
                }
            }
        }
    }
}

这是你想要的吗？

        static void Main(string[] args)
        {
            List<string> order = new List<string>() { "Full", "Partial", "Mixed" };
            var pnlist = new PalletNumberRepository().GetPalletNumbers();
            var groups = pnlist.GroupBy(x => new { x.palletstatus, x.palletno }).OrderBy(x => order.IndexOf(x.Key.palletstatus)).ThenBy(x => x.Key.palletno).ToList();
            int index = pnlist.Min(x => x.palletno);
            foreach (var group in groups)
            {
                foreach (PalletNumberRepository.PalletNumber pallet in group)
                {
                    pallet.palletno = index;
                }
                index++;
            }

        }

Answer 2

如果旧号码不重要......（这将完全重新排序）

var pallets = GetPalletNumbers()
    .GroupBy(p => p.dropno)
    .Select(g => new
    {
        DropGroup = g.Key,
        Pallets = g.OrderBy(p => p.palletstatus == "Full" ? 1 
                               : p.palletstatus == "Partial" ? 2 
                               : 3) //weights
                   .Select((p, i) => { p.palletno = i + 1; return p; })
                   // would be better to create a new object versus mutate but this works
                   .ToList()
    })
    .ToList();

如果值相同，则将值重新编号为
