C#模拟域登录

标签：

如果希望使用C#进行后台域登录，需要使用到advapi32.dll这个程序集。advapi32.dll是一个高级API应用程序接口服务库的一部分，包含的函数与对象的安全性，注册表的操控以及事件日志有关。xp系统一般位于C:\WINDOWS\system32\目录下，大小659KB。

下面是实现域登录的代码：

public class SimulateDomainService
    {
        public static bool ImpersonateValidUser(String userName, String domain, String password)
        {
            //ServiceContext.SetThreadPrincipal();
            WindowsImpersonationContext impersonationContext;

            WindowsIdentity tempWindowsIdentity;
            IntPtr token = IntPtr.Zero;
            IntPtr tokenDuplicate = IntPtr.Zero;

            if (RevertToSelf())
            {
                if (LogonUserA(userName, domain, password, LOGON32_LOGON_INTERACTIVE,
                    LOGON32_PROVIDER_DEFAULT, ref token) != 0)
                {
                    if (DuplicateToken(token, 2, ref tokenDuplicate) != 0)
                    {
                        tempWindowsIdentity = new WindowsIdentity(tokenDuplicate);
                        impersonationContext = tempWindowsIdentity.Impersonate();
                        if (impersonationContext != null)
                        {
                            CloseHandle(token);
                            CloseHandle(tokenDuplicate);
                            return true;
                        }
                    }
                }
            }
            if (token != IntPtr.Zero)
                CloseHandle(token);
            if (tokenDuplicate != IntPtr.Zero)
                CloseHandle(tokenDuplicate);
            return false;
        }
        /// <summary>

        public static bool ImpersonateValidUser()
        {
            return ImpersonateValidUser(GetValue("account"), GetValue("domain"), GetValue("pwd"));
        }
        /// <summary>

        {
            return System.Configuration.ConfigurationManager.AppSettings[key].ToString();
        }

        public static CustomReportCredentials GetReportCredentials(String account,String domain,String pwd)

注意：服务器需要在模拟登录的域名之内（属于同一域）
