Automatically Determine FTP Proxy Method

See more FTP Examples

Tries each of the five possible ProxyMethod settings and returns the value (1-5) of the ProxyMethod that succeeded. .NET Core C#

bool success = false;

// 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 = "www.example-code.com";
ftp.Username = "example-code.com";
ftp.Password = "****";

ftp.ProxyHostname = "ftp.myproxyhost.com";
ftp.ProxyPort = 21;
// Note: Your FTP Proxy server may or may not require authentication.
ftp.ProxyUsername = "myProxyUsername";
ftp.ProxyPassword = "myProxyPassword";

// The ProxyMethod should be an integer value between 1 and 5.
// If you know your FTP proxy server's authentication scheme,
// you may set it directly.  To determine the ProxyMethod,
// call DetermineProxyMethod.  A return value of -1 indicates a failure.
// A return value of 0 indicates that nothing worked.
// A return value of 1-5 indicates the ProxyMethod that was 
// successful, and this should be the value used for the ProxyMethod
// property.

int pMethod = ftp.DetermineProxyMethod();
Debug.WriteLine(Convert.ToString(pMethod));

success = ftp.Disconnect();
