CSV至C＃中的JSON

Question

I've used the online converters but they don't do exactly what I need them to do so I was hoping to write a small program to get it to convert the csv to json in the exact format I need. So lets start with the csv file:

Id,Sea,First,Last,Team,Coll,Num,Age,Hgt,Wgt,Pos,Attr/Str,Attr/Agi,Attr/Arm,Attr/Spe,Attr/Han,Attr/Intel,Attr/Acc,Attr/PBl,Attr/RBl,Attr/Tck,Attr/KDi,Attr/KAc,Attr/End,Per/Lea,Per/Wor,Per/Com,Per/TmPl,Per/Spor,Per/Soc,Per/Mny,Per/Sec,Per/Loy,Per/Win,Per/PT,Per/Home,Per/Mkt,Per/Mor,Skills/QB,Flg,Trait,Skills/RB,Skills/FB,Skills/G,Skills/T,Skills/C,Skills/WR,Skills/TE,Skills/CB,Skills/SS,Skills/FS,Skills/DE,Skills/LB,Skills/DT,Skills/K,Skills/P
,2018,David,Bush,,Stanford,19,21,76,212,QB,68,55,89,70,31,96,99,1,5,24,1,1,74,34,71,62,33,76,88,15,15,40,14,31,33,9,94,,,,,,,,,,,,,,,,,,

Now this is the output in json:

{
"Players": [{
    "Id": 2938,
    "Sea": 2018,
    "First": "Harold",
    "Last": "Dalton",
    "Team": "0",
    "Coll": "Western Kentucky",
    "Num": 87,
    "Age": 20,
    "Hgt": 76,
    "Wgt": 224,
    "Pos": "WR",
    "Attr": {
        "Str": 59,
        "Agi": 79,
        "Arm": 1,
        "Spe": 87,
        "Han": 77,
        "Intel": 38,
        "Acc": 1,
        "PBl": 1,
        "RBl": 11,
        "Tck": 21,
        "KDi": 1,
        "KAc": 1,
        "End": 58
    },
    "Per": {
        "Lea": 62,
        "Wor": 76,
        "Com": 61,
        "TmPl": 58,
        "Spor": 62,
        "Soc": 94,
        "Mny": 92,
        "Sec": 32,
        "Loy": 31,
        "Win": 68,
        "PT": 90,
        "Home": 36,
        "Mkt": 45,
        "Mor": 70
    },
    "Skills": {
        "WR": 53,
        "TE": 31
    },
    "Flg": "None",
    "Trait": "None"
},

Yes its a different player, that's not the point here :)

And here's the code I have so far, without the conversion process...

    SaveFileDialog sfd = new SaveFileDialog();
    OpenFileDialog ofd = new OpenFileDialog();
    public static string fileName;

    private void open_btn_Click(object sender, EventArgs e)
    {
        ofd.Filter = "CSV Files (.csv)|*.csv";
        ofd.Title = "Open CSV File";

        if (ofd.ShowDialog() == DialogResult.OK)
        {
            richTextBox1.LoadFile(ofd.FileName, RichTextBoxStreamType.PlainText);

            fileName = ofd.FileName;
            open_label.Text = System.IO.Path.GetFileName(fileName);
        }
    }

    private void save_btn_Click(object sender, EventArgs e)
    {
        sfd.Filter = "JSON Files (.json)|*.json";
        sfd.Title = "Save JSON File";

        if (sfd.ShowDialog() == DialogResult.OK)
        {
            //how do I convert the loaded .csv file into the json format below???
        }
    }

Here is another simple way to convert CSV to JSON object structure using Cinchoo ETL

First load the CSV file using ChoCSVReader, it gives you list of dynamic objects represents each CSV row. Then transform them to Player by exposing constructor taking CSV dynamic object and load them to its members as below

public class Player
{
    public Player(dynamic obj)
    {
        Id = ChoUtility.CastTo<int>(obj.Id);
        Sea = ChoUtility.CastTo<int>(obj.Sea);
        First = obj.First;
        Last = obj.Last;
        Team = obj.Team;
        Coll = obj.Coll;
        Num = ChoUtility.CastTo<int>(obj.Num);
        Age = ChoUtility.CastTo<int>(obj.Age);
        Hgt = ChoUtility.CastTo<int>(obj.Hgt);
        Wgt = ChoUtility.CastTo<int>(obj.Wgt);
        Pos = obj.Pos;
        Flg = String.IsNullOrEmpty(obj.Flg) ? "None" : obj.Flg;
        Trait = String.IsNullOrEmpty(obj.Trait) ? "None" : obj.Trait;

        Attr = new PlayerAttr();
        Attr.Str = ChoUtility.CastTo<int>(obj.Attr_Str);
        Attr.Agi = ChoUtility.CastTo<int>(obj.Attr_Agi);

        Per = new PlayerPer();
        Per.Lea = ChoUtility.CastTo<int>(obj.Per_Lea);
        Per.Wor = ChoUtility.CastTo<int>(obj.Per_Wor);


        Skills = new PlayerSkills();
        Skills.WR = ChoUtility.CastTo<int>(obj.Skills_WR);
        Skills.TE = ChoUtility.CastTo<int>(obj.Skills_TE);
    }

    public int Id { get; set; }
    public int Sea { get; set; }
    public string First { get; set; }
    public string Last { get; set; }
    public string Team { get; set; }
    public string Coll { get; set; }
    public int Num { get; set; }
    public int Age { get; set; }
    public int Hgt { get; set; }
    public int Wgt { get; set; }
    public string Pos { get; set; }

    public PlayerAttr Attr { get; set; }
    public PlayerPer Per { get; set; }

    public PlayerSkills Skills { get; set; }
    public string Flg { get; set; }
    public string Trait { get; set; }
}  

UPDATE:

public class Players
{
    public Player[] players { get; set; }
}
public class PlayerAttr
{
    public int Str { get; set; }
    public int Agi { get; set; }

}
public class PlayerPer
{
    public int Lea { get; set; }
    public int Wor { get; set; }

}
public class PlayerSkills
{
    public int WR { get; set; }
    public int TE { get; set; }

}

Finally use the ChoJSONWriter object to write the final object.

using (var p = new ChoCSVReader("Players.csv").WithFirstLineHeader())
{
    using (var w = new ChoJSONWriter<Players>("Players.json").Configure( c=> c.UseJSONSerialization = true).Configure(c => c.SupportMultipleContent = true))
    {
        w.Write(new RootObject { players = p.Select(e => new Player(e)).ToArray() });
    }
}

Hope this helps.
