ADSL拨号调用api来实现+命令行方法--Arvin's Blog

ADSL的所有操作都要调用RASAPI32.DLL这个dll,详细的调用方法和参数,大家可以查询MSDN。

在codeplex上有个叫dotras的项目http://dotras.codeplex.com/这个项目封装了rasapi dll的操作,大家可以下载下来使用,不用自己在封装了,关于操作方法可以参见实例,下载过来后有示例的

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)
                    {

                rs.Dispose();

//获取连接信息

我之前找过一次用API实现ADSL拨号的资料，结果发现没那么简单。网上很多源代码是很老的，根本就用不上。

后来发现了系统命令就自带命令可实现ADSL拨号。

所以这里再贴一个方式：

rasdial.exe 宽带名称宽带帐号宽带密码

说明：

rasdial.exe ---> 是windows命令

宽带名称 ---> 是创建的拨号连接的名称

宽带帐号 --->ISP给你的帐号

宽带密码 --->ISP给你的密码

示例：

运行--cmd.exe--输入下面的命令自己修改

rasdial.exe 宽带连接 0769123456@163.gd dg123456
