Question

我编写了一些代码来读取CSV文件中的数据，并将每行中的重要值保存到我想要转换为JSON的String中。虽然我仍然是C＃的新手并且没有使用任何与JSON相关的东西，但我不知道如何以最好的方式做到这一点。

这是我到目前为止的代码：

using System;
using System.IO;
using System.Collections.Generic;

namespace CSV_Importer
{
    class Program
    {
        static void Main(string[] args)
        {
            // Read the file and display it line by line.  
            String MedicalData;
            FileStream MedicalFile = new FileStream(@"C:\CSV Health-Care cs\CsvExport_01_03_2017.csv", FileMode.Open);
            StreamReader MedicalFileReader = new StreamReader(MedicalFile);

            List<Participant>List = new List<Participant>();

            MedicalData = MedicalFileReader.ReadLine();

            while ((MedicalData = MedicalFileReader.ReadLine()) != null)
            {
                //MedicalData = MedicalFileReader.ReadLine();
                //Console.WriteLine(MedicalData);

                String[] MedicalDataArray = MedicalData.Split(';');

                Participant ParticipantTemp = new Participant();
                ParticipantTemp.DateOfBirth = MedicalDataArray[0];
                ParticipantTemp.Gender = MedicalDataArray[1];
                ParticipantTemp.BmiValue = Convert.ToDouble(MedicalDataArray[9]);
                ParticipantTemp.RelativeFatMass = Convert.ToDouble(MedicalDataArray[12]);
                ParticipantTemp.AbsoluteFatMass = Convert.ToDouble(MedicalDataArray[13]);
                ParticipantTemp.FatFreeMassValue = Convert.ToDouble(MedicalDataArray[14]);
                ParticipantTemp.SkeletalMuscleMassValue = Convert.ToDouble(MedicalDataArray[15]);
                ParticipantTemp.SmmTorsoValue = Convert.ToDouble(MedicalDataArray[16]);
                ParticipantTemp.SmmRlValue = Convert.ToDouble(MedicalDataArray[17]);
                ParticipantTemp.SmmLlValue = Convert.ToDouble(MedicalDataArray[18]);
                ParticipantTemp.SmmLaValue = Convert.ToDouble(MedicalDataArray[19]);
                ParticipantTemp.SmmRaValue = Convert.ToDouble(MedicalDataArray[20]);
                ParticipantTemp.WaistCircumferenceValue = Convert.ToDouble(MedicalDataArray[291]);
                ParticipantTemp.WeightValue = Convert.ToDouble(MedicalDataArray[296]);
                ParticipantTemp.HeightValue = Convert.ToDouble(MedicalDataArray[299]);
                ParticipantTemp.TotalEnergyExpenditureValue = Convert.ToDouble(MedicalDataArray[301]);
                ParticipantTemp.RestingEnergyExpenditureValue = Convert.ToDouble(MedicalDataArray[302]);
                ParticipantTemp.FfmiValue = Convert.ToDouble(MedicalDataArray[307]);
                ParticipantTemp.FmiValue = Convert.ToDouble(MedicalDataArray[308]);
                ParticipantTemp.VisceralAdiposeTissueValue = Convert.ToDouble(MedicalDataArray[318]);

                List.Add(ParticipantTemp);

                //Console.WriteLine(MedicalDataArray[1]);
            }

            foreach (var participant in List)
            {
                Console.Write(participant.DateOfBirth);
                Console.Write(" " + participant.Gender);
                Console.Write(" " + participant.BmiValue);
                Console.Write(" " + participant.RelativeFatMass);
                Console.Write(" " + participant.AbsoluteFatMass);
                Console.Write(" " + participant.FatFreeMassValue);
                Console.Write(" " + participant.SkeletalMuscleMassValue);
                Console.Write(" " + participant.SmmTorsoValue);
                Console.Write(" " + participant.SmmRlValue);
                Console.Write(" " + participant.SmmLlValue);
                Console.Write(" " + participant.SmmLaValue);
                Console.Write(" " + participant.SmmRaValue);
                Console.Write(" " + participant.WaistCircumferenceValue);
                Console.Write(" " + participant.WeightValue);
                Console.Write(" " + participant.HeightValue);
                Console.Write(" " + participant.TotalEnergyExpenditureValue);
                Console.Write(" " + participant.RestingEnergyExpenditureValue);
                Console.Write(" " + participant.FfmiValue);
                Console.Write(" " + participant.FmiValue);
                Console.WriteLine(participant.VisceralAdiposeTissueValue);
            }
            Console.ReadLine();
        }
    }

    public class Participant
    {
        public string DateOfBirth;
        public string Gender;
        public double BmiValue;
        public double RelativeFatMass;
        public double AbsoluteFatMass;

Json.NET是将对象序列化为JSON的事实标准。它就像

一样简单

JsonConvert.SerializeObject(MedicalDataArray);

C＃将csv变量转换为JSON String
