I had a requirement to consume .PDFs and attach all of them that arrived within 30 minutes to an email with the PDFs as attachments. I created a multi part message that I named msg_Email of type System.Xml.XmlDocument. I created the message using a Construct Message shape. I then loaded the body of the message using the .LoadXML() method. I then used a helper class named EmailAttacher to attach the new messages needing to be attachments to the existing multi part email message. Here is the helper class code.
namespace EmailAttacher
{
public class MessageHelper
{
public static void AddAttachment(XLANGMessage destination, XLANGMessage attachment, string filename)
{
try
{
int count = destination.Count;
destination.AddPart(attachment[0], string.Format(“Attachment_{0}”, count));
destination[count].SetPartProperty(typeof(MIME.FileName), filename);
}
finally
{
//decrement reference count
destination.Dispose();
attachment.Dispose();
}
}
}
The message assignment shape has the following code to add the newest message to the existing message.
EmailAttacher.MessageHelper.AddAttachment(msg_Email, msg_ToAddAsAttachment,”NameOfAttachedFile”);
Don’t forget to add this, to ensure all message parts that aren’t the body are attachments.
msg_Email(SMTP.MessagePartsAttachments) = 2;
