将日期转换为ISO日期格式C＃

Question

我有一个日期值，例如：

string date = "02/14/2015" //(MM/DD/YYY)

我想将其转换为ISO日期格式。无论如何都要这样做..

Answer 1

使用DateTime.ParseExact(dateString, format, provider);功能。

https://msdn.microsoft.com/en-us/library/w2sa9yss%28v=vs.110%29.aspx

示例：

CultureInfo provider = CultureInfo.InvariantCulture;
string date = "02/14/2015";
string format = "dd/mm/yyyy";

// Result is now a DateTime and can be easily converted
DateTime result = DateTime.ParseExact(date, format, provider);

Answer 2

试试这个：

string date = "02/14/2015"

DateTime NewDate= DateTime.ParseExact(dateString, "MM/DD/YYYY", 
CultureInfo.InvariantCulture);

string NewFmt=NewDate.ToString("yyyy/MM/DD");

Answer 3

试试这个...

string date = "02/14/2015";
DateTime d2 = DateTime.Parse(date, null, DateTimeStyles.RoundtripKind);
