Detect Format

Detects the mail message format from a file extension.

Code

using DRIT.Mail;

// Load with an explicit format
IMailMessage mail = MailFile.Load("message.dat", MailMessageFormat.Eml);

// Inspect the source format of a loaded message
Console.WriteLine($"Source format: {mail.SourceFormat}");

// The MailMessageFormat enumeration values:
//   Msg   - Outlook Item (.msg)
//   Pst   - Outlook Personal Folders (.pst)
//   Eml   - Internet email message (.eml)
//   ICal  - iCalendar (.ics)
//   VCard - vCard (.vcf)
//   Mbox  - MBOX mailbox archive
//   Html  - HTML (.html)

Remarks

Use MailFile.Load(string fileName, MailMessageFormat format) when the file extension does not match the actual format, or when loading from a stream where the extension is not available.
