Fetch Single Email by UID or Sequence Number

Assuming the UID is known, download a single email by UID from an IMAP mail server. C#

bool success = false;

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

Chilkat.Imap imap = new Chilkat.Imap();

// Connect to an IMAP server.
// Use TLS
imap.Ssl = true;
imap.Port = 993;
success = imap.Connect("imap.example.com");
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Login
success = imap.Login("***","***");
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Select an IMAP mailbox
success = imap.SelectMailbox("Inbox");
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

Chilkat.Email email = new Chilkat.Email();

int uid = 2014;
bool isUid = true;

success = imap.FetchEmail(false,uid,isUid,email);
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Display the From and Subject
Debug.WriteLine(email.FromAddress);
Debug.WriteLine(email.Subject);

// Display the Body property, which is the default body.
// If an email has an HTML body, the Body property contains
// the HTML source.  Otherwise it contains the plain-text
// body.
Debug.WriteLine("---- EMAIL BODY ----");
Debug.WriteLine(email.Body);
Debug.WriteLine("--------------------");

// Display the recipients:
int j;
for (j = 0; j <= email.NumTo - 1; j++) {
    Debug.WriteLine(email.GetToName(j) + ", " + email.GetToAddr(j));
}

for (j = 0; j <= email.NumCC - 1; j++) {
    Debug.WriteLine(email.GetCcName(j) + ", " + email.GetCcAddr(j));
}

// Show the total size of the email, including body and attachments:
Debug.WriteLine(Convert.ToString(email.Size));

// When a full email is downloaded, we would use the
// email.NumAttachments property in conjunction with the
// email.GetMailAttach* methods.
// However, when an email object contains only the header,
// we need to access the attachment info differently:
int numAttach = imap.GetMailNumAttach(email);
Debug.WriteLine(Convert.ToString(numAttach));

for (j = 0; j <= numAttach - 1; j++) {
    Debug.WriteLine(imap.GetMailAttachFilename(email,j));
    int attachSize = imap.GetMailAttachSize(email,j);
    Debug.WriteLine("    size = " + Convert.ToString(attachSize) + " bytes");
}

Debug.WriteLine("--");

// Disconnect from the IMAP server.
success = imap.Disconnect();
