(C# UWP/WinRT) ConnectFailReason

The ConnectFailReason property can be examined to determine the reason why the Connect method failed. The possible values are listed in the source code below:

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

ftp.Hostname = "ftp.example.com";
ftp.Username = "login";
ftp.Password = "password";

// Connect and login to the FTP server.
bool success = await ftp.ConnectAsync();
if (success != true) {

    // The possible failure reasons are:
    // 0 = success
    // Non-SSL socket fail reasons:
    //  1 = empty hostname
    //  2 = DNS lookup failed
    //  3 = DNS timeout
    //  4 = Aborted by application.
    //  5 = Internal failure.
    //  6 = Connect Timed Out
    //  7 = Connect Rejected (or failed for some other reason)
    // SSL failure reasons:
    //  100 = Internal schannel error
    //  101 = Failed to create credentials
    //  102 = Failed to send initial message to proxy.
    //  103 = Handshake failed.
    //  104 = Failed to obtain remote certificate.
    // 300 = asynch op in progress
    // 301 = login failure.
    // 
    int failReason = ftp.ConnectFailReason;

    Debug.WriteLine("connect fail reason = " + Convert.ToString(failReason));

    Debug.WriteLine(ftp.LastErrorText);
    return;
}
