MapiAttachment

MapiAttachment class

Inherits: Aspose::Email::Mapi::MapiPropertyContainer

Represents a message attachment.

This class encapsulates an attachment, providing methods to access and manipulate its properties.

This code example loads a message from a file and iterates over each attachment. If an attachment is inline, it prints its display name. If not, it checks if the attachment is an embedded message. If so, it saves the attachment to a memory stream. If not, it saves to a specified path.

// Load the MAPI message from the specified file
var msg = MapiMessage.Load("source.msg");
 
// Iterate over each attachment in the MAPI message
foreach (var mapiAttachment in msg.Attachments)
{
 // Check if the attachment is inline
 if (mapiAttachment.IsInline)
    {
 // If inline, print its display name
        Console.WriteLine($"Inline: {mapiAttachment.DisplayName}");
    }
 else
    {
 // If not inline
 // Check if the attachment contains an embedded message
 if (mapiAttachment.ObjectData != null && mapiAttachment.ObjectData.IsOutlookMessage)
        {
 // If it's an embedded message
 // Save the attachment to a memory stream
 using (MemoryStream ms = new MemoryStream())
            {
                mapiAttachment.Save(ms);
                ms.Position = 0;
 // Load the embedded message from the memory stream
                var embeddedMessage = MapiMessage.Load(ms);
            }
        }
 else
        {
 // If it's not an embedded message
 // Save the attachment to the specified path
            mapiAttachment.Save(Path.Combine(path, mapiAttachment.LongFileName));
        }
    }
}
