In C#, How Can I Obtain A String Representation Of An ISO 8601 Date From A DateTime Object?

In C#, you can use the DateTime.ToString() method with the desired format specifier yyyy-MM-ddTHH:mm:ss.fffZ to get an ISO 8601 formatted date as a string. The Z represents the UTC time zone offset. Here’s an example:

DateTime dateTime = DateTime.Now;
string isoDate = dateTime.ToString("yyyy-MM-ddTHH:mm:ss.fffZ");
Console.WriteLine(isoDate);

Output:

2022-10-10T15:30:45.123Z

Note that this will give you the current date and time. If you have a specific DateTime object that you want to format, you can replace DateTime.Now with your object reference.
