前言
由于工作原因,需要使电脑长时间保持宽带连接状态,并且有动态拨号更换ip的需求,在网上查阅资料许久,首先找到了这篇博客:
使用C#实现ADSL自动拨号
但是本人在win8 64位的系统上并未成功,后来采用bat去实现这个功能并封装成帮助类
类代码
类代码如下
//---------------------------------------名称:基于bat批处理的ADSL动态拨号帮助类

帮助类说明
调用方式如下
ADSLIP.ChangeIp("宽带名称","宽带用户名","宽带密码");
此方式会出现控制台界面(由于运行bat),但是会自行关闭
使用DotRas进行宽带拨号
网上找的帮助类—-

allUsersPhoneBook.Open(path);
// 如果已经该名称的PPPOE已经存在,则更新这个PPPOE服务器地址
if (allUsersPhoneBook.Entries.Contains(updatePPPOEname))

// 不管当前PPPOE是否连接,服务器地址的更新总能成功,如果正在连接,则需要PPPOE重启后才能起作用
allUsersPhoneBook.Entries[updatePPPOEname].Update();
