Question

我正在使用Windows功能来模拟，以在启动Chrome驱动程序之前更改活动用户。现在，在没有模拟代码的情况下启动驱动程序可以正常工作。模拟代码也可以正常工作；我看到用户已更改。但是，当发生此更改时，此后我运行IWebDriver driver=new ChromeDriver，则会在该确切代码上触发异常，并且测试将停止。任何想法为什么会发生这种情况？

这是所使用代码的主要部分（该代码只是stackoverflow上另一篇文章的少量修改代码）

namespace localSeleniumTest.Impersonation
{
    class Program
    {
        [DllImport("advapi32.dll", SetLastError = true)]
        public static extern bool LogonUser(stringpszUsername, string pszDomain, string pszPassword,
            int dwLogonType, int dwLogonProvider, ref IntPtr phToken);

        // closes open handes returned by LogonUser
        [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
        public extern static bool CloseHandle(IntPtr handle);

        public void Impersonation()
        {
            WindowsImpersonationContext impersonationContext = null;
            IntPtr userHandle = IntPtr.Zero;
            const int LOGON32_PROVIDER_DEFAULT = 0;
            const int LOGON32_LOGON_INTERACTIVE = 2;
            string domain = Config.domain;
            string user = Config.username;
            string password = Config.password;

            try
            {
                String currentName = WindowsIdentity.GetCurrent().Name;

                // if domain name was blank, assume local machine
                if (domain == "")
                    domain = System.Environment.MachineName;

                // Call LogonUser to get a token for the user
                bool loggedOn = LogonUser(
                    user,
                    domain,
                    password,
                    LOGON32_LOGON_INTERACTIVE,
                    LOGON32_PROVIDER_DEFAULT,
                    ref userHandle
                    );

                if (!loggedOn)
                {
                    return;
                }

                // Begin impersonating the user
                impersonationContext = WindowsIdentity.Impersonate(userHandle);

                String afterImpersonationName = WindowsIdentity.GetCurrent().Name;


                /*this few lines below does not work after impersonation but 
work perfectly without the code above.*/
                    IWebDriver driver = new ChromeDriver();
                    driver.Navigate().GoToUrl("www.google.com");
                    System.Threading.Thread.Sleep(6000);
                    driver.Quit();
