asp.net-mvc-4 – IEDriverServer在使用模拟时引发错误

但是,如果在使用与当前用户不同的用户调用LogonUser后运行IEDriverServer,则会在启动时显示应用程序故障对话框.这是在EventLog中注册的信息：

Faulting application name: IEDriverServer.exe,version: 2.44.0.0,time stamp: 0x54496690

这是我用于模仿的代码.它基于我找到的所有例子,所以我没有惊喜……我们也尝试使用SimpleImpersonation packege,结果相同：

public class ImpersonationHelper
{
    public enum LogonType
    {
        Interactive = 2,Network = 3,Batch = 4,Service = 5,Unlock = 7,Cleartext = 8,// Win2K or higher
        NewCredentials = 9 // Win2K or higher
    };

    public enum LogonProvider
    {
        Default = 0,Winnt35 = 1,Winnt40 = 2,Winnt50 = 3
    };

    public enum ImpersonationLevel
    {
        SecurityAnonymous = 0,SecurityIdentification = 1,SecurityImpersonation = 2,SecurityDelegation = 3
    }

    [DllImport("advapi32.dll",SetLastError = true,CharSet = CharSet.Unicode)]
    public static extern bool LogonUser(String lpszUsername,String lpszDomain,String lpszPassword,int dwLogonType,int dwLogonProvider,out IntPtr phToken);

    [DllImport("kernel32.dll")]
    [ReliabilityContract(Consistency.WillNotCorruptState,Cer.Success)]
    [SuppressUnmanagedCodeSecurity]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool CloseHandle(IntPtr handle);

    [DllImport("advapi32.dll",CharSet = CharSet.Auto,SetLastError = true)]
    public static extern int DuplicateToken(IntPtr hToken,int impersonationLevel,ref IntPtr hNewToken);

    public sealed class Impersonator : IDisposable
    {
        public string Domain { get; private set; }
        public string User { get; private set; }
        public string Password { get; private set; }
        public LogonType Type { get; private set; }
        public LogonProvider Provider { get; private set; }

        private WindowsImpersonationContext _context;
        private IntPtr _token;

        [PermissionSetAttribute(SecurityAction.Demand,Name = "FullTrust")]
        public Impersonator(string domain,string user,string password,LogonType type = LogonType.Interactive,LogonProvider provider = LogonProvider.Default)
        {
            Domain = domain;
            User = user;
            Password = password;
            Type = type;
            Provider = provider;
            _token = IntPtr.Zero;

            Logon();
        }

        public void Dispose()
        {
            Undo();
        }

        private void Logon()
        {
            try
            {
                if (!LogonUser(User,Domain,Password,(int)Type,(int)Provider,out _token))
                {
                    int ret = Marshal.GetLastWin32Error();
                    throw new Exception(String.Format("LogonUser failed with error code : {0}",ret));
                }

                _context = WindowsIdentity.Impersonate(_token);
            }
            catch (Exception exception)
            {
                var message = exception.Message;
                Undo();
            }
        }

        private void Undo()
        {
            try
            {
                if (_token != IntPtr.Zero)
                {
                    CloseHandle(_token);
                    _token = IntPtr.Zero; // Clean _token so Undo() could be called several times
                }

                if (_context != null)
                {
                    _context.Undo();
                    _context = null; // Clean _context so Undo() could be called several times
                }
            }
            catch (Exception exception)
            {
                var message = exception.Message;
                // Releasing resources failed...
            }
        }
    }
}

引发异常的代码是：

using (new ImpersonationHelper.Impersonator("WIN-NKLTTMMUEPD","tester","tester"))
{
    using (IWebDriver driver = new InternetExplorerDriver())
    {
        driver.Url = _appAddress;
        return null;
    }
}

有谁知道如何防止出现此错误？非常感谢你提前.
