ADSL拨号连接 | 拨号连接

dotras是一个提供远程访问服务的组件，使用它可以方便的

进行宽带拨号连接

由于不同的系统中dotras调用的底层api可能不同，所以使用时要根据不同的系统使用不同的dotras。

dotras目前有以下几个包，在nuget中可以找到。每个包都有对应的系统

WIN8 - Windows 8, Windows 8 Server
WIN7 - Windows 7, Windows 2008 Server R2 (aka Windows 7 Server)
WIN2K8 - Windows Vista, Windows 2008 Server
WINXP - Windows XP, Windows 2003 Server
WIN2K - Windows 2000, Windows 2000 Server (baseline)

详细说明可以参照dotras doucument

以下是使用dotras进行的简单实现ADSL拨号连接。
