C#/ASP.NET Selenium WebDriver - Re-using Cookies

I want to:

What i want to do, is login ONCE, save the cookies from that, and add them to any other FirefoxDriver i want to open.

Right now I'm trying to save the cookies in

public ReadOnlyCollection<Cookie> Cookies { get; set; }

which is the result of

WebDriver.Manage().Cookies.AllCookies;

Assuming login worked and cookies were saving in the above, I have this:

        WebDriver = new FirefoxDriver();
        WebDriver.Navigate().GoToUrl("http://www.example.com");

        if (cookies != null)
        {
            var s = WebDriver.Manage().Cookies;  //Logged out cookies
            WebDriver.Manage().Cookies.DeleteAllCookies(); //Delete all of them
            var sd = WebDriver.Manage().Cookies; //Make sure theyre deleted
            foreach (var cookie in cookies)
            {
                WebDriver.Manage().Cookies.AddCookie(cookie);
            }
            var ss = WebDriver.Manage().Cookies; 
            WebDriver.Navigate().GoToUrl("http://example.com/requiresloginpage");
        }

The problem is, howevering over "ss" in this case, gives this exception error

AllCookies = 'ss.AllCookies' threw an exception of type
'OpenQA.Selenium.WebDriverException'
base {System.Exception} = {"Unexpected problem getting cookies"}
InnerException = {"Cookie name cannot be null or empty string\r\nParameter name: name"}

I'm passing 8 cookies (total number when youre logged in) - and all of them seem set and ok. Not sure what I'm doing wrong

In order to save cookies, you should tell selenium to use a specified profile. For some reason I can't get it to use my normal Chrome profile, but this solution will allow you to log in one time, and afterward, selenium will remember cookies.

ChromeOptions options = new ChromeOptions();
options.AddArguments(@"user-data-dir=C:\Users\YOU\AppData\Local\Google\Chrome\User Data\NAMEYOUCHOOSE");
//specify location for profile creation/ access
ChromeDriver driver = new ChromeDriver(options);

Simply put, this code creates a save location for a profile, which does include cookies. using this code, it is not necessary to write code that saves or loads cookies, Chrome will handle that.

Please note that the location where chrome saves your profiles may be different than mine, and I have only successfully used a directory that leads to the same location as my regular Chrome profile. This profile exists in the form of a folder, not a file.

Generally Selenium do not support cross-session cookies.

Most easy way is to use Serialization. You need to create wrapper class around selenium's cookie and make it serializable. And create class CookiesManager where will be 2 methods: SaveSession() -- to save and RestoreSession() - to restore from serialized file.

Another way is to save some cookies information into some temp cookies file. Like.... Csv or XML. Sample of this way you can see here: Keep user logged in - save cookies using web driver but only for c#.
