Console validator

Good evening, I need to program a user validator in C# (I have visual studio). Console style. I need from a list . txt the value of "id=" in the URL to be changed.

https://www.sitevalidador.com.br/bi5/Paginas/cliente/Login.aspx?id=idatualnalista&pc=05

If you have such a message on the web page as an "OK", then take the value of the current id and log in the console saying it is valid.

For example I added a list with three id’s being two of them invalid

2446
4452
4445

Because the last id in the list is valid, display the message in the console:

VALID 4445

And finally, save all "valid" ids to a . txt in the same directory of . exe.

Thank you very much!

I hope you understand, I have no idea how to do this. If possible, please help me!

  • you want to make a bot that enters a page by providing a url with the user id and pick up the answer to say whether it is valid or not, that’s it?

Your question is a little wide, but I’ll put an example here for you of how to read this file and get exactly the piece you need.

public void ReadFile()
{
    string line;
    using (StreamReader reader = new StreamReader(@"c:\temp\filelist.txt"))
    {
        line = reader.ReadLine();
        Console.WriteLine(line.Substring(line.IndexOf("id=", StringComparison.Ordinal), 7).Replace("id=", ""));
    }
    Console.ReadKey();
}

Then you adapt it to your code and do its validations.. this will return the piece of your URL ID inside the file.
