你用的是什么命令?
What command are you using?
my.network
my.network
My.Computer.Network.IsAvailable对我来说很好,虽然我只是有
a单一连接到局域网。
您可以随时ping几个热门地址,看看你是否有一个
互联网连接。 EG www.google.com , www.microsoft.com ,
www.yahoo.com 它们不太可能在同一时间关闭。
您可以在try / catch语句中发送webrequest,如果它会抛出一个
的例外,然后连接到互联网就会出现问题,而且你没有连接到
。
也没有一个活跃的互联网连接并不意味着你没有连接到网络。
HTH,

My.Computer.Network.IsAvailable works fine for me, although I just have
a single connection to a LAN.
You could always ping a few popular addresses to see if you have an
Internet connection. E.G www.google.com, www.microsoft.com,
www.yahoo.com its unlikely that they will all be down at the same time.
You could send a webrequest in a try/catch statement, if it throws an
exception then there is a problem connecting to the internet and you are
not connected.
Also not having an active Internet connection doesn''t mean that you are
not connected to a Network.
HTH,
