Hi 大家好，我想问一个问题，怎么在程序里获取到用户最后一次登录的时间？

注意是：是我们现在用的电脑的真实的登录用户，不是程序里的用户。

我用的方法是：

http://technet.microsoft.com/zh-cn/subscriptions/aa394221 微软的Win32 的API。。

public static List<string> GetSysUserNames()
        {
            List<string> temp = new List<string>();
            string iuser = "";
            string lastLogin = "";
            GetLastLoginTime = new List<string>();

            ConnectionOptions options = new ConnectionOptions();
            options.Impersonation = ImpersonationLevel.Impersonate;
            options.EnablePrivileges = true;
            ManagementScope scope = new ManagementScope("\\root\\cimv2", options);
            scope.Options.EnablePrivileges = true;
            scope.Options.Impersonation = ImpersonationLevel.Impersonate;
            scope.Connect();
            SelectQuery query = new SelectQuery("Select * from Win32_NetworkLoginProfile ");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            foreach (ManagementBaseObject useraccount in searcher.Get())
            {
                iuser = useraccount["Name"].ToString();
                if (!iuser.Trim().StartsWith("NT AUTHORITY") && !iuser.Trim().Equals(""))
                {
                    if (useraccount["LastLogon"] == null)
                    {
                        lastLogin = "00/00/0000";
                    }
                    else
                    {
                        if (useraccount["LastLogon"].ToString().Contains("*"))
                        {
                            lastLogin = "00/00/0000";
                        }
                        else
                        {
                            lastLogin = useraccount["LastLogon"].ToString().Substring(0, 8);
                        }
                    }
                    GetLastLoginTime.Add(CastLastLoginFormat(lastLogin));
                    temp.Add(iuser);
                }
            }
            return temp;
        }

但是这里的运用在Win7 下面获取到的时间是不正确的呢，但是在XP下面是正确的呢！~~~~~很郁闷啊很郁闷，看看谁还有更好的办法？？？？

想了好久啊，貌似真的没有办法啦~~~~

谢谢大家了。。分只能到200.。木有办法啦。
