Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server. C#

bool success = false;

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

Chilkat.Socket socket = new Chilkat.Socket();

//  To use a SOCKS4 or SOCKS5 proxy, simply set the following
//  properties prior to calling Connect.  The connection may be SSL/TLS or 
//  non-secure - both will work with a SOCKS proxy.
//  The SOCKS hostname may be a domain name or 
//  IP address:
socket.SocksHostname = "www.mysocksproxyserver.com";
socket.SocksPort = 1080;
socket.SocksUsername = "myProxyLogin";
socket.SocksPassword = "myProxyPassword";
//  Set the SOCKS version to 4 or 5 based on the version
//  of the SOCKS proxy server:
socket.SocksVersion = 5;
//  Note: SOCKS4 servers only support usernames without passwords.
//  SOCKS5 servers support full login/password authentication.

//  Connect to port 5555 of 192.168.1.108.
//  hostname may be a domain name or IP address.
string hostname = "192.168.1.108";
bool ssl = false;
int maxWaitMillisec = 20000;
success = socket.Connect(hostname,5555,ssl,maxWaitMillisec);
if (success != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

//  Set maximum timeouts for reading an writing (in millisec)
socket.MaxReadIdleMs = 10000;
socket.MaxSendIdleMs = 10000;

//  The server (in this example) is going to send a "Hello World!" 
//  message.  Read it:
string receivedMsg = socket.ReceiveString();
if (socket.LastMethodSuccess != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

//  Close the connection with the server
//  Wait a max of 20 seconds (20000 millsec)
success = socket.Close(20000);

Debug.WriteLine(receivedMsg);
