IMAP Download All Email One at a Time

Demonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) .NET Core C#

bool success = false;

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

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

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

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

// Once the mailbox is selected, the NumMessages property
// will contain the number of messages in the mailbox.
// You may loop from 1 to NumMessages to
// fetch each message by sequence number.

bool bUid = false;
string mimeStr;
int i;
int n = imap.NumMessages;
for (i = 1; i <= n; i++) {

    // Download the email by sequence number.
    mimeStr = imap.FetchSingleAsMime(i,bUid);

    // ... your application may process each MIME string...
}

// An alternative is to download each email in the form of an
// email object, like this:
Chilkat.Email email = new Chilkat.Email();
for (i = 1; i <= n; i++) {

    // Download the email by sequence number.
    success = imap.FetchEmail(false,i,bUid,email);

    // ... your application may process the email object...

}

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