// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

bool success;

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

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

// Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
topLevelMime.NewMultipartMixed();

// Append the ptMime as a child.
topLevelMime.AppendPart(ptMime);
Debug.WriteLine(topLevelMime.GetMime());
Debug.WriteLine("****");

// The topLevelMime contains:
// --------------------------
// 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
// 
// 	--------------010907090104040508040404
// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body
// 	--------------010907090104040508040404--
// 

// IMPORTANT: A copy of the MIME passed in AppendPart is appended.
// Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
// For example:
ptMime.SetBody("this is the new plain text body.");
// topLevelMime is unchanged.
Debug.WriteLine(topLevelMime.GetMime());
Debug.WriteLine("****");

// To change the content in topLevelMime, we must get the text/plain part.
// For example:
Chilkat.Mime ptMime2 = topLevelMime.GetPart(0);
ptMime2.SetBody("this is the new plain text body.");

// Now topLevelMime is changed.
Debug.WriteLine(topLevelMime.GetMime());
