如何通过组合重复数据显示为单个对象来显示列表对象中的所有数据？

Question

这是我在文件中的输入存储：

   50|Carbon|Mercury|M:4;C:40;A:1
    90|Oxygen|Mars|M:10;C:20;A:00
    90|Serium|Jupiter|M:3;C:16;A:45
    85|Hydrogen|Saturn|M:33;C:00;A:3

这里50,90,90,85表示权重，M,C,A表示每个元素中的比例。 p>

现在我想显示每个元素（即碳、氧等）从最高到最低，如果有多个具有相同权重的元素，将它们分组到一个单个权重并按按行星的字母顺序（火星、木星）然后元素（碳、氧等）对它们进行排序

预期输出：

1)90 
  Serium;Jupiter (sorted alphabetically by planet name).
  compounds:M:3;C:16;A:45
  Oxygen;Mars
  compounds:M:10;C:20;A:00

2)85
  Hydrogen;Saturn
  M:33;C:00;A:3

3)50
  Carbon;Mercury
  M:4;C:40;A:1

这就是我的做法：

public class Planets
    {
        public int Number { get; set; }  //This field points to first cell of every row.output 50,90,90,85
        public string name { get; set; } //This field points to Second cell of every row.output Hallogen,Oxygen,Hydrogen
        public string object { get; set; } ////This field points to third cell of every row.output Mercury,Mars,Saturn
        public List<proportion> proportion { get; set; } //This will store all proportions with respect to planet object.
         //for Hallogen it will store 4,40,1.Just store number.ignore M,C,A initials.
         //for oxygen it will store 10,20,00.Just store number.ignore M,C,A initials.
    }

    public class proportion
    {
        public int Number { get; set; } 
    }

List<Planets> Planets = new List<Planets>();
                        using (StreamReader sr = new StreamReader(args[0]))
                        {
                            String line;
                            while ((line = sr.ReadLine()) != null)
                            {
                                Planets planet = new Planets();
                                String[] parts = line.Split('|');
                                planet.Number = Convert.ToInt32(parts[0]);
                                planet.name = parts[1];
                                planet.obj = parts[2];

                                String[] smallerParts = parts[3].Split(';');
                                planet.proportion = new List<proportion>();
                                foreach (var item in smallerParts)
                                {
                                    proportion prop = new proportion();
                                    prop.Number =                                    
                                    Convert.ToInt32(item.Split(':')[1]);
                                    planet.proportion.Add(prop);
                                }
                                Planets.Add(planet);
                            }
                        }
                     var data = Planets.OrderByDescending(t => t.Number).ToList();//Highest to lowest.
                      foreach (var item in data)
                        {
                            //What to do for same elements
                        }

我可以成功地在我的行星列表对象中添加所有 4 行，如下所示：

 Planets[0]:
    {
       Number:50
       name: Carbon
       object:Mercury
       proportion[0]:
                 {
                     Number:4
                 },
        proportion[1]:
                 {
                     Number:40
                 },
    proportion[2]:
                 {
                     Number:1
                 }
    }
Etc.......

我遇到的唯一问题是 显示相同数字的重量（预期输出 1）并按字母顺序按行星（火星，木星）排序，然后按元素（碳、氧等）

我在 LinqPad 上创建了以下代码来实现您期望的结果，如果您仍需要更改，请告诉我，一个简单的 Linq 查询将有助于实现结果：

void Main()
{   
    List<Input> customList = Input.Create();

    var result = customList.GroupBy(x=>x.Weight,x=>new {x.Element1,x.Element2,x.Detail})
                       .Select(y=>new {
                                       key = y.Key,
                                       collection = y.OrderBy(z=>z.Element2)
                                      }
                               ).OrderByDescending(h=>h.key);     


    foreach(var n in result)
    {
       Console.WriteLine("Weight :: " + n.key);

       foreach(var g in n.collection)
       {
           Console.WriteLine(g.Element1 + ";" + g.Element2);
           Console.WriteLine("Compounds:" + g.Detail);
       }
    }
}

public class Input
{
  public int Weight {get; set;}
  public string Element1 {get; set;}
  public string Element2 {get; set;}
  public string Detail {get; set;}

  public Input(int w, string e1, string e2, string d)
  {
    Weight = w;
    Element1 = e1;
    Element2 = e2;
    Detail = d; 
  }

  public static List<Input> Create()
  {
    List<Input> returnList = new List<Input>();

    returnList.Add(new Input(50,"Carbon","Mercury","M:4;C:40;A:1"));
    returnList.Add(new Input(90,"Oxygen","Mars","M:10;C:20;A:00"));
    returnList.Add(new Input(90,"Serium","Jupiter","M:3;C:16;A:45"));
    returnList.Add(new Input(85,"Hydrogen","Saturn","M:33;C:00;A:3"));

    return (returnList);    
  }
}
