代码

这是实际涉及的代码

类变量

private DateTime datecalc;
private string _datecode;

类属性

public string DateCode
{
    get { return _datecode; }
    set 
    {
        int _CodeYear = 0;
        byte _CodeWeek = 0;
        byte _CodeDayOfWeek = 0;
        _datecode = value;
        if (_datecode.Length == 5)
        {
            //Get the number of weeks to add
            _CodeWeek = Convert.ToByte(_datecode.Substring(2, 2));
            //Get the day of the week in the final week
            _CodeDayOfWeek = Convert.ToByte(_datecode.Substring(4));
        }
        else if (_datecode.Length == 4)
        {
            //Get the number of weeks to add
            _CodeWeek = Convert.ToByte(_datecode.Substring(2, 1));
            //Get the day of the week in the final week
            _CodeDayOfWeek = Convert.ToByte(_datecode.Substring(3));
        }
        if (_datecode.Length == 4 || _datecode.Length == 5)
        {
            _CodeWeek--;
            _CodeDayOfWeek--;
            _CodeYear = (2000 + Convert.ToInt32(_datecode.Substring(0, 2)) - 1);
            datecalc = new DateTime(_CodeYear, 7, 1);
            datecalc.AddDays(-1);
            do { datecalc = datecalc.AddDays(1); } 
            while (datecalc.DayOfWeek != DayOfWeek.Saturday);
            datecalc = datecalc.AddDays((_CodeWeek * 7) + _CodeDayOfWeek);
        }
    }
}

public DateTime CalculatedDate
{
    get { return datecalc; }
}
