可以就如何转换时间跨度或INT到ISO8601时长串任何人提醒如 HTTP解释：？//en.wikipedia.org/wiki/ISO_8601#Durations

1小时30分钟会导致PT1H30M，例如：

  INT持续时间= 90;
字符串isoString = duration.ToIsoDuration（）;
 

解决方案

找到了解决办法我自己，所以我想我会分享：

 时间跨度时间跨度=新的时间跨度（0，值，0）;
   返回XmlConvert.ToString（时间跨度）;
 

Can anyone advise on how to convert a timespan or int to an ISO8601 duration string as explained in http://en.wikipedia.org/wiki/ISO_8601#Durations?

"1 hour and 30 minutes" would result in "PT1H30M", for example:

int duration = 90;
string isoString = duration.ToIsoDuration();

found the solution myself, so I thought I'd share:

   TimeSpan timeSpan = new TimeSpan(0, value, 0);
   return XmlConvert.ToString(timeSpan);
