It seems there might be a confusion in your request. Polly is a resilience and transient-fault-handling library in C# for dealing with issues like network failures, timeouts, and other transient errors. It is not directly related to parsing courses or web scraping.

If you are looking to parse a course from a website using C#, you might want to use a combination of HTTP requests and HTML parsing libraries. Here's a basic example using the HtmlAgilityPack library for HTML parsing and HttpClient for making HTTP requests

Install HtmlAgilityPack:

You can install the HtmlAgilityPack library using NuGet Package Manager Console:

Install-Package HtmlAgilityPack

Example Code

Here's a simple example of how you might use HttpClient and HtmlAgilityPack to parse course information from a website:

using System;
using System.Net.Http;
using HtmlAgilityPack;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        // URL of the course page
        string courseUrl = "https://example.com/courses";

        // Make an HTTP request to get the HTML content
        using (HttpClient client = new HttpClient())
        {
            string htmlContent = await client.GetStringAsync(courseUrl);

            // Use HtmlAgilityPack to parse the HTML
            HtmlDocument doc = new HtmlDocument();
            doc.LoadHtml(htmlContent);

            // Extract course information (modify as per the HTML structure)
            HtmlNodeCollection courseNodes = doc.DocumentNode.SelectNodes("//div[@class='course']");
            if (courseNodes != null)
            {
                foreach (HtmlNode courseNode in courseNodes)
                {
                    string courseTitle = courseNode.SelectSingleNode(".//h2")?.InnerText.Trim();
                    string courseDescription = courseNode.SelectSingleNode(".//p")?.InnerText.Trim();

                    Console.WriteLine($"Title: {courseTitle}");
                    Console.WriteLine($"Description: {courseDescription}");
                    Console.WriteLine();
                }
            }
            else
            {
                Console.WriteLine("No course information found on the page.");
            }
        }
    }
}

This is a basic example, and you'll need to adapt it based on the actual HTML structure of the course page you are working with.

To pass a Selenium WebDriver instance to a Python decorator, you can create a custom decorator that takes the WebDriver instance as an argument. Here's an example of how to do this:

First, create a custom decorator that accepts the WebDriver instance:

def webdriver_decorator(driver):
    def decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            return func(driver, *args, **kwargs)
        return wrapper
    return decorator

Create a function that takes the WebDriver instance as an argument and performs the desired action:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

def my_function(driver, search_query):
    driver.get('https://example.com')
    search_box = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.ID, 'search-box')))
    search_box.send_keys(search_query)
    search_box.send_keys(Keys.RETURN)

Apply the custom decorator to the function and pass the WebDriver instance:

@webdriver_decorator
def my_function_with_decorator(driver, search_query):
    return my_function(driver, search_query)

Now you can use the decorated function and pass the WebDriver instance:

driver = webdriver.Chrome()
driver.get('https://example.com')

search_results = my_function_with_decorator(driver, 'your search query')

In this example, the my_function_with_decorator function is the same as the my_function function, but it is wrapped by the webdriver_decorator. When you call my_function_with_decorator, you need to pass the WebDriver instance as the first argument.

To check if a proxy server is working, you can follow these steps:

1. Open your web browser and go to a website that is not blocked by your proxy server.

2. In the address bar, enter the proxy server address and port number in the following format: http://proxy-server-address:port-number

3. Press Enter and wait for the page to load. If the page loads successfully, it means your proxy server is working.

4. If the page does not load or you see an error message, it means your proxy server is not working or is blocked by the website you are trying to access.

Alternatively, you can use online tools like Proxy Checker (https://www.proxychecker.com/) to test your proxy server. These tools will provide you with information on whether your proxy server is working or not.

In AnyDesk, in order to ensure maximum security of transmitted traffic, you can use proxies, including encryption of traffic. The setting is made through the regular menu of the application. You will need to go to "Options", select "Connection", specify the proxy and port number. Connection is made automatically after that.

Paid proxies are definitely better and more reliable than free ones. How do you test them? You can simply use the Hidemy Name service. It also shows which protocols the service uses and how reliable the connection is.
