Chilkat.MailMan mailman = new Chilkat.MailMan();

// ...

int numBodyLines = 3;
int fromIndex = 0;
int toIndex = 9;

// ------------------------------------------------------------------------
// The GetHeaders method is deprecated:

Chilkat.EmailBundle bundleObj = mailman.GetHeaders(numBodyLines,fromIndex,toIndex);
if (mailman.LastMethodSuccess == false) {
    Debug.WriteLine(mailman.LastErrorText);
    return;
}

// ------------------------------------------------------------------------
// Do the equivalent using FetchRange.
// Your application creates a new, empty EmailBundle object which is passed 
// in the last argument and filled upon success.
