Use WebClient with socks proxy in C#

Use WebClient with socks proxy in C#

You can use the WebClient class in C# to make HTTP requests, and you can configure it to use a SOCKS proxy by setting the appropriate properties in the WebProxy object.

Here's an example of how to use WebClient with a SOCKS proxy:

WebClient client = new WebClient(); // Set the proxy server and port WebProxy proxy = new WebProxy("socks://localhost:1080"); // Set the credentials for the proxy server, if required proxy.Credentials = new NetworkCredential("username", "password"); // Assign the proxy to the WebClient client.Proxy = proxy; // Make the request and read the response string result = client.DownloadString("https://www.example.com"); Console.WriteLine(result);

In this example, we create a new WebClient object and a WebProxy object that represents the SOCKS proxy server. We set the Address property of the WebProxy object to the URL of the proxy server, including the socks:// scheme and the port number.

If the proxy server requires authentication, we can set the Credentials property of the WebProxy object to a NetworkCredential object that contains the username and password.

Finally, we set the Proxy property of the WebClient object to the WebProxy object we created, and make an HTTP request using the DownloadString method. The response is returned as a string, which we print to the console.

Note that SOCKS proxies are less common than HTTP proxies, and not all proxy servers support the SOCKS protocol. If you're unable to connect to the proxy server using the WebClient class, you may need to use a different library or a lower-level networking API, such as Socket.
