Load an Email from a Chilkat XML String

Demonstrates the Chilkat Email.LoadXmlString method, which loads an email from a Chilkat XML representation held in a string, typically obtained from GetXml. On success, the loaded message replaces the entire current email. This example serializes one email to XML, then reconstructs it in a second object.

Background: This is the in-memory (string) counterpart to LoadXml, which reads from a file. Pairing GetXml with LoadXmlString lets you store an email's full state as text in a database column, cache, or message queue, then rebuild the Email object later — without touching the filesystem.
