How to Convert an ISO 8601 String to a .NET DateTime Object?

Convert ISO 8601 String to .NET DateTime

Introduction

Transforming a DateTime object to ISO 8601 format is a common task, but its conversion back to DateTime is less documented in C#. This article demonstrates how to efficiently parse an ISO 8601 string into a DateTime object.

Parsing ISO 8601 String

To create a DateTime object from an ISO 8601 string, utilize DateTime.Parse() with the following considerations:

• For timestamps without a time zone offset (e.g., "2010-08-20T15:00:00"), use the following code:

DateTime d1 = DateTime.Parse("2010-08-20T15:00:00");

• For timestamps with a 'Z' time zone offset (e.g., "2010-08-20T15:00:00Z"), use DateTimeStyles.RoundtripKind:

DateTime d2 = DateTime.Parse("2010-08-20T15:00:00Z", null, System.Globalization.DateTimeStyles.RoundtripKind);

Example

Consider the ISO 8601 string "2010-08-20T15:00:00Z". To convert it to a DateTime object using RoundtripKind:

DateTime d3 = DateTime.Parse("2010-08-20T15:00:00Z", null, System.Globalization.DateTimeStyles.RoundtripKind);

This approach correctly handles the time zone information and accurately represents the DateTime value.
