c# - 异常 "String was not recognized as a valid DateTime"

Question

我收到字符串未被识别为有效的日期时间。以下函数中出现异常

public int GetTime()
{
    string time = "17-07-2015 01:11:25"
    time.Replace('-', '/');

    DateTime oldDate = Convert.ToDateTime(time);
    // Difference in days, hours, and minutes.
    DateTime newDate =Convert.ToDateTime(DateTime.Now.ToString("dd-MM-yyyy HH:mm:ss"));

    TimeSpan ts = oldDate - newDate;
    // Difference in days.
    int differenceInhours = ts.Hours;
    differenceInhours = differenceInhours * 60;
    int differenceInMinutes = ts.Minutes + 1;
    int BalanceTime = differenceInhours + differenceInMinutes;

    return BalanceTime;
}

17-07-2015 01:11:25 此日期存储在数据库中

Answer 1

你可以尝试这个，因为你知道日期时间的格式:

 DateTime oldDate = DateTime.ParseExact(time,"dd-MM-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
