Finding all network adapters using WMI in C# .NET

In this post we saw how to retrieve all logical drives using Windows Management Intrumentation (WMI). We’ll follow a very similar technique to enumerate all network adapters.

The following code prints all non-null properties of all network drives found on the local – “root” – computer:

private static void ListAllNetworkAdapters()
{
	ManagementObjectSearcher networkAdapterSearcher = new ManagementObjectSearcher("root\\cimv2", "select * from Win32_NetworkAdapterConfiguration");
	ManagementObjectCollection objectCollection = networkAdapterSearcher.Get();

	Console.WriteLine("There are {0} network adapaters: ", objectCollection.Count);

	foreach (ManagementObject networkAdapter in objectCollection)
	{
		PropertyDataCollection networkAdapterProperties = networkAdapter.Properties;
		foreach (PropertyData networkAdapterProperty in networkAdapterProperties)
		{
			if (networkAdapterProperty.Value != null)
			{
				Console.WriteLine("Network adapter property name: {0}", networkAdapterProperty.Name);
				Console.WriteLine("Network adapter property value: {0}", networkAdapterProperty.Value);
			}
		}
		Console.WriteLine("---------------------------------------");
	}
}

Here’s an extract of the printout from my PC:
