c# - c#中的日期格式转换

Question

如何将 04/09/2013 8:09:10 PM 转换为 09/04/2013 (MM-dd-yyyy)。我尝试转换，但它以 09 作为日期，以 04 作为月份。

请帮忙

[HttpPost]
public string getdailynote(DateTime selectedDate)
//selectedDate gets date as 04/09/2013 8:09:10 PM
{
    string x = selectedDate.ToString("MM-dd-yyy", CultureInfo.InvariantCulture);
    string daily;
    DateTime dt = Convert.ToDateTime(x);
    //dt gets value as {09/04/2013 12:00:00 AM} but 09 as date and 04 as month
    Dnote.RealDate =dt;
    daily = _scheduler.GetDailyNote(Dnote);
    return daily;
}

Answer 1

it is taking 09 as date and 04 as month

是的，因为你说过，改

"MM-dd-yyy"

到

"dd/MM/yyyy h:mm:ss tt"

DateTime.ParseExact("04/09/2013 8:09:10 PM","dd/MM/yyyy h:mm:ss tt", CultureInfo.InvariantCulture);

Demo

现在，如果你想把它转换成这种格式的字符串MM-dd-yyyy:

string result = dt.ToString("MM-dd-yyyy", CultureInfo.InvariantCulture);
