To install the Selenium library in C# for Visual Studio, you can use the NuGet Package Manager, which is integrated into Visual Studio. Follow these steps to install Selenium in your C# project:

1. Open Visual Studio:

   • Launch Visual Studio and open your C# project.

2. Open the Package Manager Console:

   • Go to View -> Other Windows -> Package Manager Console to open the Package Manager Console.

3. Run the Install-Package Command:

   • In the Package Manager Console, run the following command to install the Selenium.WebDriver package:

Install-Package Selenium.WebDriver

• • Press Enter to execute the command. This will download and install the Selenium WebDriver package and its dependencies.

• Verify Installation:

  • After the installation is complete, you should see output indicating that the package has been installed successfully.

• Install Selenium.Support (Optional):

  • Depending on your requirements, you may also want to install Selenium.Support, which includes additional support classes and utilities for Selenium. Run the following command:

Install-Package Selenium.Support

Add Using Statements in Your Code:

• In your C# code file, add the following using statements at the top:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;  // Use the appropriate browser namespace (e.g., Firefox, Edge, etc.)

• • Choose the appropriate browser namespace based on the WebDriver you plan to use (e.g., Chrome, Firefox).

• Download WebDriver Executable (Optional):

  • If you are using a specific browser (e.g., Chrome, Firefox), you need to download the corresponding WebDriver executable.

  • Place the WebDriver executable in a location accessible to your project.

• Instantiate WebDriver in Your Code:

  • In your C# code, instantiate the WebDriver using the downloaded WebDriver executable path. For example, for Chrome:

IWebDriver driver = new ChromeDriver("path/to/chromedriver");

8. • Replace "path/to/chromedriver" with the actual path to your ChromeDriver executable.

   • Ensure that you manage the WebDriver instance properly (e.g., closing it after use).

That's it! You have successfully installed the Selenium library in your C# project. You can now use the Selenium WebDriver to automate browser interactions in your C# application.

Proxy autoconfiguration is a feature that allows a client to automatically discover and configure the settings required to connect to a proxy server. This is typically done using a configuration file or script that provides instructions on how to set up the client's proxy settings.

The most common format for proxy autoconfiguration is the Proxy Auto-Config (PAC) file. A PAC file is a JavaScript file that contains functions to determine the appropriate proxy server(s) to use for a given URL or network condition. When a client is configured to use a PAC file, it will automatically execute the PAC script to determine the best proxy server for each request.

Another format for proxy autoconfiguration is the Web Proxy Autodiscovery Protocol (WPAD). WPAD uses a Dynamic Host Configuration Protocol (DHCP) option or a Domain Name System (DNS) query to locate a configuration script (usually named "wpad.dat") that contains the proxy settings. The client then executes the script to determine the appropriate proxy server(s) to use.

Proxy autoconfiguration makes it easier for clients to connect to the correct proxy server without manual configuration, especially in large organizations or networks where proxy settings may change frequently. It also allows for centralized management of proxy settings, making it simpler to update or change configurations across the entire network.

The proxy domain most often refers to the IP address where the server is located. It can only "learn" the IP address of the user when processing the traffic. But in most cases it does not store such information later for security reasons.

In Telegram on PC, proxies can be set up through the application settings. You need to open the "Advanced settings" item, then - select "Connection type". By default, the Windows system proxy is used, but you can specify it manually or disable it altogether.

You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).
