c# - 如何用分钟解析日期包含值 60？

Question

当分钟包含值 60 时出现异常

var date = "30/10/14 08:60";
var result = DateTime.ParseExact(date, "dd/MM/yy HH:mm", CultureInfo.InvariantCulture, DateTimeStyles.None);

如何正确解析它？

Answer 1

要么传递一个正确的值(>=0 || <=59)要么使用这个:

var date = "30/10/14 08:60";
DateTime dateResult;
bool canParse = DateTime.TryParseExact(date, "dd/MM/yy HH:mm", CultureInfo.InvariantCulture, DateTimeStyles.None, out dateResult);
if (!canParse)
{
    string datePart = date.Split().First();
    DateTime dtOnly;
    if (DateTime.TryParseExact(datePart, "dd/MM/yy", CultureInfo.InvariantCulture, DateTimeStyles.None, out dtOnly))
    {
        string timePart = date.Split().Last();
        string hourPart = timePart.Split(':')[0];
        string minutePart = timePart.Split(':').Last();
        int hour, minute;
        if (int.TryParse(hourPart, out hour) && int.TryParse(minutePart, out minute))
        {
            TimeSpan timeOfDay = TimeSpan.FromHours(hour) + TimeSpan.FromMinutes(minute);
            dateResult = dtOnly + timeOfDay;  // 10/30/2014 09:00:00
        }
    }
}
