How to authenticate (user/password) proxy in c# selenium chrome driver

Question

I have a HTTP/HTTPS proxy which need to authenticate using username and password. How do I do that using C# selenium chrome webdriver?

string host = proxies[count].Split(':')[0];
int port = Convert.ToInt32(proxies[count].Split(':')[1]) + 1;

string prox = host + ":" + port.ToString();

OpenQA.Selenium.Proxy proxy = new OpenQA.Selenium.Proxy();
proxy.HttpProxy = prox;
proxy.SslProxy = prox;
options.Proxy = proxy;

options is the ChromeOptions class which I assign to the driver.

I created little package for yor problem (https://github.com/RDavydenko/OpenQA.Selenium.Chrome.ChromeDriverExtensions)

Install Package:

Install-Package OpenQA.Selenium.Chrome.ChromeDriverExtensions -Version 1.2.0

Use for your ChromeOptions:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Chrome.ChromeDriverExtensions;
...
var options = new ChromeOptions();

// Add your HTTP-Proxy
options.AddHttpProxy(PROXY_HOST, PROXY_PORT, PROXY_USER, PROXY_PASSWORD);

var driver = new ChromeDriver(options); // or new ChromeDriver(AppDomain.CurrentDomain.BaseDirectory, options);

driver.Navigate().GoToUrl("https://whatismyipaddress.com/"); // Check your IP

Instead of PROXY_HOST, PROXY_PORT, PROXY_USER, PROXY_PASSWORD, use the parameters of your proxy
