Convert dateTime to ISO format yyyy-mm-dd hh:mm:ss in C# [duplicate]

Question

Is there a standard way in .NET/C# to convert a datetime object to ISO 8601 format yyyy-mm-dd hh:mm:ss?

Or do I need to do some string manipulation to get the date string?

Answer 1

To use the strict ISO8601, you can use the s (Sortable) format string:

 myDate.ToString("s"); // example 2009-06-15T13:45:30 

It's a short-hand to this custom format string:

myDate.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss"); 

And of course, you can build your own custom format strings.
