如何在nodatime中获得基于周的第一个日历？

using NodaTime;
using NodaTime.Text;

public class Program
{
    public static void Main()
    {
        LocalDate date = new LocalDate(2022, 1, 1); // 要查询的日期
        int weekYear = date.GetIsoWeekYear(); // 获取ISO周年
        int week = 1; // 要查询的周数

        // 获取指定周年的总周数
        IsoWeekYearRule isoWeekYearRule = IsoWeekYearRules.IsoWeekYear;
        int totalWeeks = isoWeekYearRule.GetWeeksInWeekYear(weekYear);

        // 将周参数限制在1到总周数之间
        week = Math.Max(1, Math.Min(week, totalWeeks));

        // 调整日期为指定的周和周年
        LocalDate firstDateOfWeek = date.WithWeekOfWeekYear(weekYear, week);

        Console.WriteLine("第一个日历日期: " + firstDateOfWeek);
    }
}
