Im currently using this snippet that lets me rout the connection over http proxy

Code

public static TcpClient ProxyTcpClient(string targetHost, int targetPort, string httpProxyHost, int httpProxyPort, string proxyUserName, string proxyPassword)
       {

           const BindingFlags Flags = BindingFlags.NonPublic | BindingFlags.Instance;
           Uri proxyUri = new UriBuilder
           {
               Scheme = Uri.UriSchemeHttp,
               Host = httpProxyHost,
               Port = httpProxyPort
           }.Uri;
           Uri targetUri = new UriBuilder
           {
               Scheme = Uri.UriSchemeHttp,
               Host = targetHost,
               Port = targetPort
           }.Uri;

           WebProxy webProxy = new WebProxy(proxyUri, true);
           webProxy.Credentials = new NetworkCredential(proxyUserName, proxyPassword);
           WebRequest request = WebRequest.Create(targetUri);
           request.Proxy = webProxy;
           request.Method = "CONNECT";
           HttpWebResponse response = (HttpWebResponse)request.GetResponse();
           Stream responseStream = response.GetResponseStream();
           Type responseType = responseStream.GetType();
           PropertyInfo connectionProperty = responseType.GetProperty("Connection", Flags);
           var connection = connectionProperty.GetValue(responseStream, null);
           Type connectionType = connection.GetType();
           PropertyInfo networkStreamProperty = connectionType.GetProperty("NetworkStream", Flags);
           NetworkStream networkStream = (NetworkStream)networkStreamProperty.GetValue(connection, null);
           Type nsType = networkStream.GetType();
           PropertyInfo socketProperty = nsType.GetProperty("Socket", Flags);
           Socket socket = (Socket)socketProperty.GetValue(networkStream, null);

           return new TcpClient { Client = socket };
       }

I need to do the same thing but only with socks5 proxy.
Thanks  🤝

Haven't seen anyone do it this way before, that's pretty cool. However you would probably come out better using a library that supports different types of proxies for sockets.

.Net not have SOCKS4/SOCKS5 implementation, you have to write your own SOCKS5 client. See https://tools.ietf.org/html/rfc1928
