IMAP LastResponse and LastResponseCode

Demonstrates the IMAP LastResponse and LastResponseCode properties. C#

bool success = false;

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

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

//  Use TLS
imap.Ssl = true;
imap.Port = 993;
success = imap.Connect("imap.gmail.com");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

//  Authenticate, but with an intentionally incorrect password
//  so we can see the contents of the LastErrorText, and also
//  the LastResponse and LastResponseCode properties.
success = imap.Login("my_login","my_intentionally incorrect_password");
if (success == true) {
    Debug.WriteLine("Successfull login, but this example is meant to demonstrate an error, such as a failed login.");
    return;
}

//  Let's look at the LastErrorText, and also the LastResponse and LastResponseCode.
Debug.WriteLine("LastResponseCode = " + imap.LastResponseCode);
Debug.WriteLine("LastReponse = " + imap.LastResponse);
Debug.WriteLine("LastErrorText = " + imap.LastErrorText);

//  Sample output:

//  LastResponseCode = AUTHENTICATIONFAILED
//  LastReponse = aaab NO [AUTHENTICATIONFAILED] Invalid credentials (Failure)
//  LastErrorText = ChilkatLog:
//    Login:
