bool success;

// Start with an empty MIME object...
Chilkat.Mime mime = new Chilkat.Mime();

// Initialize it as multipart/alternative.
mime.NewMultipartAlternative();

// Create a text/plain part.
Chilkat.Mime ptMime = new Chilkat.Mime();
ptMime.SetBodyFromPlainText("This is the plain text body.");
Debug.WriteLine(ptMime.GetMime());
Debug.WriteLine("****");

// The text/plain part looks like this:

// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body.

// Create a text/HTML part.
Chilkat.Mime htmlMime = new Chilkat.Mime();
htmlMime.SetBodyFromHtml("<html><body><p>This is the <b>HTML body</b></p></body></html>");
Debug.WriteLine(htmlMime.GetMime());
Debug.WriteLine("****");

// The text/html part looks like this:

// 	Content-Type: text/html
// 	Content-Transfer-Encoding: 7bit
// 
// 	<html><body><p>This is the <b>HTML body</b></p></body></html>

// Add both parts as children of the multipart/alternative
mime.AppendPart(ptMime);
mime.AppendPart(htmlMime);
Debug.WriteLine(mime.GetMime());

// This the result.  The boundary string was automatically generaetd.

// 	Content-Type: multipart/alternative; boundary="------------080803090906030708030908"
// 
// 	--------------080803090906030708030908
// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body.
