Implements a part used to encapsulate Unicode characters.
This example demonstrates how to add parts to a message. First, a "multipartalternative" part
containing two alternative text parts is added. Second, a resource part containing an
image is added.
private MailMessage addCustomParts(MailMessage message)
{
//Add custom header field to message
message.Headers.Add("X-Alt-Message", new HeaderField("X-Alt-Message", "Message with Alternatives"));
//Create and add alternative parts to a multipart part
Textpart part1 = new Textpart("This is alternative 1.");
part1.Headers.Add("X-Alt", new HeaderField("X-Alt", "Alternative 1"));
Textpart part2 = new Textpart("This is alternative 2.");
part2.Headers.Add("X-Alt", new HeaderField("X-Alt", "Alternative 2"));
Multipart multipart = new Multipart(Multipart.Alternative);
multipart.Parts.Add(part1);
multipart.Parts.Add(part2);
//Add a MultiPart to the MailMessage
message.Parts.Add(multipart);
//Add a Resource part to the MailMessage
Resource resource = new Resource(new FileStream(Application.StartupPath + "\\myImage.jpg", FileMode.Open), "myImage.jpg");
resource.ContentType = new ContentType("image/jpeg");
resource.ContentId = "<myImage>";
message.Parts.Add(resource);
return message;
}
Private Function addCustomParts(ByVal message As MailMessage) As MailMessage

'Create and add alternative parts to a multipart part

Dim part2 As New Textpart("This is alternative 2.")
part2.Headers.Add("X-Alt", New HeaderField("X-Alt", "Alternative 2"))
