升级到 VS 2010 后,我得到了这个 FormatException。没什么特别的。代码:
private void ManageDateEditControls()
{
apoDateEdit.DateTime = DateTime.Parse(string.Format("01/{0}/{1}", DateTime.Now.Month-1, DateTime.Now.Year));
eosDateEdit.DateTime = DateTime.Parse(string.Format("{0}/{1}/{2}", GetLastDayOfMonth(DateTime.Now.Month + 1),
DateTime.Now.Month - 1, DateTime.Now.Year)); <-- FormatException occurs in this line.
}
private static int GetLastDayOfMonth(int month)
{
// set return value to the last day of the month
// for any date passed in to the method
// create a datetime variable set to the passed in date
DateTime dtTo = new DateTime(DateTime.Now.Year, month, 1);
// overshoot the date by a month
dtTo = dtTo.AddMonths(1);
// remove all of the days in the next month
// to get bumped down to the last day of the
// previous month
dtTo = dtTo.AddDays(-(dtTo.Day));
// return the last day of the month
return dtTo.Day;
}
如果您在 2010 年 6 月 31 日运行,假设您现在得到。我认为这是一个有效的日期。我已经测试了生成的日期并且没问题......这个项目在 VS 2008 中工作时从未遇到过这个问题。
有任何想法吗?
