如何在C#中使用csvHelper将两个单独列中的日期和时间合并为一个新的datetime列

using CsvHelper;
using System.Globalization;
using System.IO;

date,time
2022-01-01,10:30:00
2022-01-02,14:45:00
2022-01-03,18:15:00

public class DateTimeData
{
    public string Date { get; set; }
    public string Time { get; set; }
    public DateTime DateTime { get; set; }
}

string filePath = "path/to/dates.csv";
List<DateTimeData> data = new List<DateTimeData>();

using (var reader = new StreamReader(filePath))
using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
{
    csv.Configuration.HasHeaderRecord = true;
    csv.Configuration.MissingFieldFound = null;
    
    while (csv.Read())
    {
        DateTimeData record = new DateTimeData();
        record.Date = csv.GetField<string>("date");
        record.Time = csv.GetField<string>("time");

        // Merge date and time into a new DateTime column
        record.DateTime = DateTime.ParseExact($"{record.Date} {record.Time}", "yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture);

        data.Add(record);
    }
}
