//  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;
hostname = "192.168.1.108";
bool ssl;
ssl = false;
int maxWaitMillisec;
maxWaitMillisec = 20000;
success = socket.Connect(hostname,5555,ssl,maxWaitMillisec);
if (success != true) {
    MessageBox.Show(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;
receivedMsg = socket.ReceiveString();
if (receivedMsg == null ) {
    MessageBox.Show(socket.LastErrorText);
    return;
}

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

MessageBox.Show(receivedMsg);
