This post provides a class that converts an RFC 822 formatted text representation of a date time to a DateTime object in C#. Really Simple Syndication (RSS) documents, according to the RSS specification, require that all date-times in RSS conform to the Date and Time Specification as outlined in RFC 822. Therefore, when working with RSS documents in AspNetCore and C#, it is necessary to convert the date-time in the RSS Document to a datetime object in C#. With understanding that the DateTime.Parse and DateTime.ParseExact methods of the C# datetime object have been tested and do not handle the parsing of all forms of an RFC 822 compliant date, it was deemed necessary to develop a more robust solution.    Read More.
