MSNdis_StatusMediaDisconnect 和设备唯一名称
我正在使用 ManagementEventWatcher 来观察使用 System.Management 的网络电缆的断开情况。
使用 WQL 的 ManagementEventWatcher：SELECT * FROM MSNdis_StatusMediaDisconnect,
当 EventArrived 时，会触发以下方法：
private void ServiceNetWorkStatusWmiDisconnected(object sender, EventArrivedEventArgs args)
{
string instanceName = args.NewEvent.Properties["InstanceName"].Value as string;
ServiceNetWorkStatusWmi = string.Format("Network disconnected ({0})", instanceName);
Console.WriteLine(ServiceNetWorkStatusWmi);
}
问题是：
我有 2 个网络接口，来自同一制造商，并且两种情况下，InstanceName 具有相同的值，但我无法识别拔出哪个网络！
我已经尝试了 EventArrivedEventArgs 中的所有属性，但它们没有设备的约束 ID...例如设备 ID。
如何查明网络接口是否被拔掉？
I'm using ManagementEventWatcher to watch the disconnection of network cable using System.Management.
ManagementEventWatcher with the WQL: SELECT * FROM MSNdis_StatusMediaDisconnect,
and the following method is fired, when EventArrived:
private void ServiceNetWorkStatusWmiDisconnected(object sender, EventArrivedEventArgs args)
{
string instanceName = args.NewEvent.Properties["InstanceName"].Value as string;
ServiceNetWorkStatusWmi = string.Format("Network disconnected ({0})", instanceName);
Console.WriteLine(ServiceNetWorkStatusWmi);
}
The problem is:
I have 2 network interfaces, from the same manufacturer , and both case, the InstanceName has the same value and I can´t identify what network unplugged!
I have tried all properties from EventArrivedEventArgs, but they don´t have a constraint id for device... like an Device Id.
How can I find out witch network interface was unplugged?

查看“Win32_NetworkAdapter.NetConnectionID”。这是 - 在我的机器上 [!!] - 您将在网络连接 [控制面板] 中看到的字符串完全相同，并且它应该是相同的值，出现在“MSNdis_EnumerateAdapter.InstanceName=”中。
也许，这有帮助！？

Have a look to the "Win32_NetworkAdapter.NetConnectionID". This is - at my machine [!!] - the excact same string you'll see in the network connections [control panel] and it should be the same value, apearing in "MSNdis_EnumerateAdapter.InstanceName=".
May be, this helps!?
