Implementation Guide

Let’s break down how to list all recipients of an email message.

Listing Direct Recipients

Overview

Listing direct recipients helps understand the communication flow effectively.

Step-by-Step Implementation

  1. Initialize Watermarker: Load your MSG file using Watermarker.
  2. Retrieve Email Content: Access the email content via GetContent<EmailContent>().
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Retrieve the email content.
    EmailContent content = watermarker.GetContent<EmailContent>();

    // Loop through direct recipients and output their addresses.
    foreach (EmailAddress address in content.To)
    {
        Console.WriteLine(address.Address);
    }
}
  • Parameters & Return Values: Watermarker takes a file path and load options. The method GetContent<EmailContent>() retrieves the message details.

Listing CC Recipients

Overview

Identifying CC recipients helps in tracking email threads effectively.

Step-by-Step Implementation

  1. Iterate Over CC Field: Use a loop to access each CC recipient’s address.
foreach (EmailAddress address in content.Cc)
{
    Console.WriteLine(address.Address);
}

Listing BCC Recipients

Overview

BCC recipients are often hidden from other email participants, making this step essential for full transparency.

Step-by-Step Implementation

  1. Iterate Over BCC Field: Similarly loop through the BCC field to reveal all hidden addresses.
foreach (EmailAddress address in content.Bcc)
{
    Console.WriteLine(address.Address);
}
