Fun with sockets in C#.
- Connect to a SOCKS proxy server
- SOCKS 4 and 4A: TCP CONNECT
- SOCKS 5: TCP CONNECT with optional username and password authentication
- Connect to an HTTP server without WinHTTP (e.g. HttpClientHandler)
- Use the custom delegating handler
NetworkHandlerwithHttpClient - HTTP/1.1
- HTTPS
- Chunked responses
- Most of the features provided by
HttpClient - Arbitrary sockets (e.g. connected to a SOCKS proxy server!)
- Automatic redirects (with
RedirectingHandler) - Automatic decompression (with
DecompressingHandler) - Cookies (with
CookieHandler)
- Use the custom delegating handler
There's probably a lot of bugs with NetworkHandler... it's not very thoroughly tested.
Install-Package Knapcode.SocketToMe
using (var httpClient = new HttpClient(new NetworkHandler()))
using (var response = httpClient.GetAsync("http://icanhazip.com/").Result)
{
Console.WriteLine("{0} {1}", (int) response.StatusCode, response.ReasonPhrase);
Console.WriteLine(response.Content.ReadAsStringAsync().Result.Trim());
}Talk to a website through Tor! Have Tor Browser running at the same time to try this demo out. Port 9150 is the default port for Tor Browser.
// Tor support SOCKS 4, 4A, and 5
var socksEndpoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 9150);
var socks5Client = new Socks5Client();
var socket = socks5Client.ConnectToServer(socksEndpoint);
socket = socks5Client.ConnectToDestination(socket, "icanhazip.com", 80);
using (var proxiedStream = new NetworkStream(socket))
using (var writer = new StreamWriter(proxiedStream))
using (var reader = new StreamReader(proxiedStream))
{
writer.WriteLine("GET / HTTP/1.1");
writer.WriteLine("Host: icanhazip.com");
writer.WriteLine();
writer.Flush();
Console.WriteLine(reader.ReadToEnd().Trim());
