Answer 1

As per issue 6832 logging is not implemented yet for C# bindings. So there might not be an easy way to get this working as of now.

Answer 2

C# bindings to the Chrome console logs are finally available in Selenium 4.0.0-alpha05. Selenium 3.141.0 and prior do not have support.

Before instantiating a new ChromeDriver object, set the logging preference in a ChromeOptions object and pass that into ChromeDriver:

ChromeOptions options = new ChromeOptions();   
options.SetLoggingPreference(LogType.Browser, LogLevel.All);
ChromeDriver driver = new ChromeDriver(options);

Then, to write the Chrome console logs to a flat file:

    public void WriteConsoleErrors()
    {
        string strPath = "C:\\ConsoleErrors.txt";
        if (!File.Exists(strPath))
        {
            File.Create(strPath).Dispose();
        }

        using (StreamWriter sw = File.AppendText(strPath))
        {
            var entries = driver.Manage().Logs.GetLog(LogType.Browser);
            foreach (var entry in entries)
            {
                sw.WriteLine(entry.ToString());
            }
        }
    }
