MSNdis_MediaConnectStatus - NdisMediaConnectStatus :
(0 = connected?, 1 = not connected?)

with Windows XP:
Win32_NetworkAdapter - NetConnectionStatus :

using System.Management;

static void ReportConnection2000()
{
ManagementClass mc = new ManagementClass( @"root\WMI", @"MSNdis_MediaConnectStatus", null );
ManagementObjectCollection moc = mc.GetInstances();
foreach( ManagementObject mo in moc )
{
string name = (string) mo["InstanceName"];
bool active = (bool) mo["Active"];
uint status = (uint) mo["NdisMediaConnectStatus"];
Console.WriteLine( " {0}\n\tActive:{1} Media Status:{2}", name, active, status );
}
}

static void ReportConnectionXP()
{
ManagementClass mc = new ManagementClass( @"Win32_NetworkAdapter" );
ManagementObjectCollection moc = mc.GetInstances();
foreach( ManagementObject mo in moc )
{
string name = (string) mo["Name"];
object val = mo["NetConnectionStatus"];
if( val != null )
Console.WriteLine( " {0}\n\tConnection Status:{1}", name, (ushort) val );
else
Console.WriteLine( " {0}\n", name );
}
}

to bitsbird(一瓢.net):
谢谢啦!
using System.Management 这个命名空间是如何得到到的(.Net 2003)

添加引用啊,工具箱,右键,添加

name = (string) mo["InstanceName"];
active = (bool) mo["Active"];
status = (uint) mo["NdisMediaConnectStatus"];
这些[]中的串我怎样可以得到呢？

with Windows 2000 & XP, UNDOCUMENTED:
MSNdis_MediaConnectStatus - NdisMediaConnectStatus :
(0 = connected?, 1 = not connected?)

with Windows XP:
Win32_NetworkAdapter - NetConnectionStatus :

using System.Management;

{
ManagementClass mc = new ManagementClass( @"root\WMI", @"MSNdis_MediaConnectStatus", null );
ManagementObjectCollection moc = mc.GetInstances();

if( val != null )
Console.WriteLine( " {0}\n\tConnection Status:{1}", name, (ushort) val );
else
Console.WriteLine( " {0}\n", name );
}
}


如果返回0则表示连接；

如果返回1则表示没连接；

上面得到的是本地的连接状态；
