我需要读取 C# 中的 CSV 文件并将数据放入列表中，然后将数据转储到 SQL 数据库数据库中。

我感兴趣的类是使用 CsvHelper。

这是 CSV 文件中的两个示例数据：

1,2013-05-14,NISSAN,059 7013,1995,VAN,Deisel,NISSAN,0000,NISSAN,Red,MARADANA,op1,description,p1.jpg+p2.jpg+p3.jpg,r1+r2+r3

2,2013-05-14,NISSAN2,059-7013,1995,VAN,Deisel,NISSAN,0000,NISSAN,Red,MARADANA,op1,description,p1.jpg+p2.jpg+p3.jpg,r1+r2+r3

这是 CSV 文件的类

class Vehicle
    {
        public int ID { get; set; }
        public string ClosingDate { get; set; }
        public string Model { get; set; }
        public string Reg { get; set; }
        public string YearOfManufacture { get; set; }
        public string VehicleType { get; set; }
        public string Fuel { get; set; }
        public string Brand { get; set; }
        public string Mileage { get; set; }
        public string Make { get; set; }
        public string Colour { get; set; }
        public string VehicleYard { get; set; }
        public string BasicOptions { get; set; }
        public string Description { get; set; }
        public List<string> Photos { get; set; }
        public List<string> Regions { get; set; }
    }

我尝试使用以下代码读取 CSV 文件：

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            CsvHelperRead();

            Console.Read();
        }

        private static void CsvHelperRead()
        {

            CsvConfiguration config = new CsvConfiguration();
            config.HasHeaderRecord = false;

            using (var reader = new CsvReader(new StreamReader(@"C:\Users\afshandc\Desktop\0729\vTest.csv"), config))
            {
                while (reader.Read())
                {
                    Console.WriteLine(reader.GetField(1));
                }
            }
        }
    }
}

我需要阅读 CSV 文件并将其放到此列表中。

 class CSV
    {
        public List<Vehicle> ReadVechileCSV()
        {







        }
    }

在你的CsvHelperRead你可以做：

using (var reader = new CsvReader(new StreamReader(@"C:\Users\afshandc\Desktop\0729\vTest.csv"), config))
     {
        while (reader.Read())
        {
           string line = reader.GetField(1);
           string[] classParams = line.Split(',');
           Vehicle v = new Vehicle()
          {
           ID = int.Parse(classParams[0]),
           ClosingDate = classParams[1],
           Model = classParams[2],
           Reg = classParams[3],
           YearOfManufacture = classParams[4],
           VehicleType = classParams[5],
           Fuel = classParams[6],
           Brand = classParams[7],
           Mileage = classParams[8],
           Make = classParams[9],
           Colour = classParams[10],
           VehicleYard = classParams[11],
           BasicOptions = classParams[12],
           Description = classParams[13],
           Photos = GetJoinedByPlus(classParams[14]),
           Regions = GetJoinedByPlus(classParams[15])
          };
        }
     }

  private List<string> GetJoinedByPlus(string p)
  {
     List<string> rtVal = new List<string>();
     rtVal.AddRange(p.Split('+'));
     return rtVal;
  }

假设你有一个车辆的构造函数接收它的参数..
