检测互联网V.本地lan连接 [英] Detect Internet V. local lan connection

问题描述

有没有反正Windows api来检测Windows 7计算机的网络连接是否是互联网连接或无线网络连接的局域网连接？
Windows 7和Vista在网络图标（仅限本地v。本地和互联网）中指示这一点，是否总是以系统方式获取该信息？

Is there anyway with Windows api to detect whether a Windows 7 computer's network connection is an internet connection or a LAN connection without internet access?
