C# : Converting DateTime to format YYYY-MM-DDThh:mm:ssZ

I found that lots of people were searching to convert the datetime into the universal format. Following can be used for the same.

myDateTime.ToString(“u”)

OR

string strDate = DateTime.UtcNow.ToString(“yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss’Z’”, DateTimeFormatInfo.InvariantInfo);

The custom format string is “yyyy’-‘MM’-‘dd HH’:’mm’:’ss’Z’”.
