How to set Chrome preferences using Selenium Webdriver .NET binding?

Question

Here is what I\'m using, user agent can be successfully set, while download preferences cannot.

Windows 7, Chrome 26, Selenium-dotnet-2.31.2, chromedriver_win_26.0.1

Answer 1

The Selenium dotNet driver does not support setting the chrome.prefs out of the box. The problem is that chrome.prefs must be defined as prefs under the chromeOptions node. The ChromeOptions class does not contain this variable, so you'll need to create your own ChromeOptions class:

public class ChromeOptionsWithPrefs: ChromeOptions
{
    public Dictionary prefs { get; set; }
}

public static void Initialize()
{
    var options = new ChromeOptionsWithPrefs();
    options.prefs = new Dictionary
    {
        { "intl.accept_languages", "nl" }
    };
    _driver = new ChromeDriver(@"C:\path\chromedriver", options);
}
