Residential Static Ip SOCKS5 Proxy

And it depends on what purpose the proxy is used for. But you should definitely give preference to paid proxies. They are more reliable, always available, and with that comes a guarantee of privacy. Unfortunately, personal data is often stolen from free proxies.

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.

If Selenium doesn't see the driver from Selenium.WebDriver.ChromeDriver, it could be due to a few reasons. Here are some steps to troubleshoot and resolve the issue:

Check the ChromeDriver version:

Make sure you're using the correct version of ChromeDriver that matches the version of the Chrome browser installed on your system. You can download the appropriate version of ChromeDriver from here.

Update the ChromeDriver path:

Ensure that the path to the ChromeDriver executable is correctly specified in your code. If you're using the ChromeOptions class to set the path, make sure you're using the correct property name. For example, in C#, use the ExecutablePath property:

ChromeOptions options = new ChromeOptions();
options.AddArgument("--headless");
options.ExecutablePath = @"C:\path\to\chromedriver.exe";

using (ChromeDriver driver = new ChromeDriver(options))
{
    driver.Navigate().GoToUrl("your_url");
    // Rest of your code
}

Replace C:\path\to\chromedriver.exe with the actual path to the ChromeDriver executable on your system.

1. Check for multiple ChromeDriver versions:

Sometimes, having multiple versions of ChromeDriver installed on your system can cause issues. Make sure there are no conflicting versions of ChromeDriver on your system and that the correct version is being used.

2. Check for antivirus or security software interference:

Sometimes, antivirus or security software can interfere with the execution of ChromeDriver. Try temporarily disabling your antivirus or security software to see if it resolves the issue. If it does, you may need to add an exception for ChromeDriver or change your antivirus settings.

3. Check the console output:

Examine the console output for any error messages or warnings that might provide more information about the issue. This can help you identify the root cause of the problem and find a suitable solution.

If you've tried all these steps and are still encountering issues, please provide more information about your system, including the operating system, Chrome browser version, and the specific error message or problem you're facing. This will help diagnose the issue further and find a suitable solution.

VPN is considered a more advanced technology for anonymization on the Internet. The main (but not the only) difference between VPN is the encryption of all traffic. But this decreases the connection speed and also increases the response time of the remote server. A proxy works slightly faster in this respect.

Most users use A-Parser for this purpose. It is one of the best applications for checking web applications. There is a corresponding tab, "Proxy server", in the standard menu of A-Parser. It is where you can specify the settings for the connection. And in the "Tools" section you can use parameters for parsing.
