如何将日期从yyyyMMdd格式转换为mm-dd-yyyy格式

我想将包含yyyyMMdd格式的日期的字符串转换为mm-dd-yyyy DateTime格式。 我怎么得到它？

Answer 1

 var dateString = "20050802"; var date = myDate = DateTime.ParseExact(dateString, "yyyyMMdd", System.Globalization.CultureInfo.InvariantCulture); 

善良。

Answer 2

 public static DateTime ConvertDate(string date, string pattern) { DateTime retval = DateTime.MinValue; if (System.DateTime.TryParseExact(date, pattern, System.Globalization.CultureInfo.InvariantCulture, DateTimeStyles.None, out retval)) return retval; // Could not convert date.. return DateTime.MinValue; } DateTime myDate = ConvertDate("20101230", "yyyyMMdd"); 

Answer 3

 CultureInfo provider = CultureInfo.CreateSpecificCulture("en-UK"); string dateString = "19850121"; //in yyyyMMdd format string oldFormat = "yyyyMMdd"; DateTime result = DateTime.ParseExact(dateString, oldFormat, provider); //MM/dd/yyyyformat
