How can I remove google chrome cookies

Question

I'm trying to remove cookies of chrome browser. Firstly I declared the path

string chromeLocation1 = "C:\\Users\\" + Environment.UserName.ToString() + "\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\Local Storage";

When I try to run my remove code "The file is in use by another program or user" error appears. So I tried to kill chrome.exe's proccess

foreach (var process in Process.GetProcessesByName("chrome.exe"))
{
    process.Kill();
}

But now it gives me "Access Denied" error even I run it as administrator. What should I do to remove these cookies?

Solution

You can delete all cookies with selenium framework.

1) Install selenium framework - Selenium WebDriver and Selenium WebDriver Support Classes (the easiest way to do this is by using NuGet)

2) Use the following code to delete all cookies:

var chromeUserData = "C:\\Users\\" + Environment.UserName.ToString(CultureInfo.InvariantCulture) + "\\AppData\\Local\\Google\\Chrome\\User Data";
var chromeAdvancedSettings = "chrome://settings/clearBrowserData";
var options = new ChromeOptions();
options.AddArgument("--lang=en");
options.AddArgument("--user-data-dir=" + chromeUserData);
options.LeaveBrowserRunning = false;
var driver = new ChromeDriver(options);
driver.Navigate().GoToUrl(chromeAdvancedSettings);

var frame = driver.FindElement(By.XPath("//iframe[@src='chrome://settings-frame/clearBrowserData']"));
var frameDriver = driver.SwitchTo().Frame(frame);
var dropDown = new SelectElement(frameDriver.FindElement(By.Id("clear-browser-data-time-period")));
dropDown.SelectByIndex(4);
var elm = driver.FindElement(By.Id("delete-cookies-checkbox"));
if (!elm.Selected) elm.Click();
elm = driver.FindElement(By.XPath("//button[@id='clear-browser-data-commit']"));
elm.Click();
var waiter = new WebDriverWait(driver, TimeSpan.FromSeconds(60));
waiter.Until(wd => wd.Url.StartsWith("chrome://settings"));
driver.Navigate().GoToUrl("chrome://newtab");

I installed it but it says "ChromeDriver" namespace not found

@JayGatsby try using this namespace: using OpenQA.Selenium.Chrome;

[JayGatsby]

code works without error but when I execute it a dos screen appears with this text and cookies are not deleted "Starting ChromeDriver 2.13.307647 (5a7d0541ebc58e69994a6fb2ed930f45261f3c29) on port 22774 Only local connections are allowed. "

@JayGatsby check my answer again :)

Be careful with this approach. It can delete cookies you do not want to delete because you cannot choose domains in this Chrome tab. You may be logged out from sites you do not want to.
