Question

Hey looking to convert this string into datetime

20101119T162837

And then also how to compare this string to current time so I can say, i.e:

30 Mins difference or 2 hours 10 min difference etc

Answer 1

Use DateTime.ParseExact()…

var strValue = "20101119T162837";

var dateValue = DateTime.ParseExact(strValue, "yyyyMMdd'T'HHmmss", CultureInfo.CurrentCulture);
var diff = dateValue - DateTime.Now;
Console.WriteLine("difference: {0:HH}h{0:mm}", diff);

edit: I’m not sure about the default format so you can try the simple Parse method first like George Stocker recommended
