adsl自动拨号 重拨 换ip 功能

自动拨号换IP方法：

List<string> historyIps = new List<string>();
        private void ChangeIP()
        {
            SysConfig.IsChangeIp = true;
            QQHelper.WriteLog("更换IP");
        HANDUPCON:
            string oldIpAddress = "";
            RasConnection oldConn = null;
            GetIPAddress(out oldIpAddress, out oldConn);
            string entryName = "";
            if (oldConn != null)
            {
                entryName = oldConn.EntryName;
                RasIPInfo ipAddresses = (RasIPInfo)oldConn.GetProjectionInfo(RasProjectionType.IP);
                string oldIp = ipAddresses.IPAddress.ToString();
                ipAddresses = null;
                QQHelper.WriteLog("现在的IP是"   oldIp);
                bool isUp = false;
                try
                {
                    Console.WriteLine("开始挂断");
                    oldConn.HangUp(10 * 1000);
 
                    Thread.Sleep(SysConfig.RasHangUpSleepTime);
                    if (RasConnection.GetActiveConnectionById(oldConn.EntryId) != null)
                    {
                        Console.WriteLine("结束挂断失败，重新挂断");
                        goto HANDUPCON;

                }
                catch (Exception ex)
                {
                    QQHelper.WriteLog("宽带连接挂断失败，"   ex.Message);
                }
            }
        CHANGEIP:
            try
            {
                var dt = SqliteHelper.GetDataTable("select * from sys_config");
                RasDialer rs = new RasDialer();
                if (entryName == "")

                dt.Dispose();
                rs.Dial();
                rs.Dispose();
 
            }
            catch (Exception ex)
            {
                QQHelper.WriteLog("宽带连接拨号失败，"   ex.Message);
                Thread.Sleep(SysConfig.DialFaildSleepTime);
                goto CHANGEIP;
            }
            if (oldConn != null)

                {
                    QQHelper.WriteLog("IP和上次重复，重新拨号");
                    Thread.Sleep(SysConfig.DialFaildSleepTime);

                    if (historyIps.Count >= SysConfig.IPLoopCount)
                    {

                        historyIps.Add(ipAddresses);
                    }
                    historyIps.Add(ipAddresses);
                }

            }
            SysConfig.IsChangeIp = false;
        }

获取连接信息：

private void GetIPAddress(out string ipAddress, out RasConnection oldConn)
        {
            oldConn = null;
            ipAddress = "";
            var conns = RasConnection.GetActiveConnections();
            foreach (var conn in conns)
            {
                if (conn.Device.DeviceType.ToLower() == "pppoe")
                {
                    oldConn = conn;
                    break;
                }
            }
            conns = null;
            if (oldConn != null)
            {
                try
                {
                    RasIPInfo ipAddresses = (RasIPInfo)oldConn.GetProjectionInfo(RasProjectionType.IP);
                    ipAddress = ipAddresses.IPAddress.ToString();
                    ipAddresses = null;
                }
                catch { }
 
 
            }
        }
