Get MAC Address Problem

[david]

Hi All,

I have to get the MAC address in my program. But I didn't have the correct
property name of management object. And I don't know how to get it. Can some
one help me?

Below is my code.

Thanks,



ManagementClass adapters = new ManagementClass("Win32_NetworkAdapter");

string mac = "";
adapters.Get();
int ix =adapters.Properties.Count;
ix = adapters.Properties.Count;
foreach (ManagementObject adapter in adapters.GetInstances())
{
mac = adapter["Name"].ToString() + " " ;
mac += adapter["MACAddress"].ToString(); <--- crashed here,
propertyname is wrong.

adapter["MACAddress"] could be null

so test it before calling ToString()

if(adapter["MACAddress"] != null)
mac += adapter["MACAddress"].ToString();

Hello David,

Thanks for posting in the group.

Here is a code sample in newsgroup that we often used to get Mac address:

Dim mc As System.Management.ManagementClass
Dim mo As ManagementObject
mc = New ManagementClass("Win32_NetworkAdapterConfiguration")
Dim moc As ManagementObjectCollection = mc.GetInstances()
For Each mo In moc
If mo.Item("IPEnabled") = True Then
MsgBox("MAC address " & mo.Item("MacAddress").ToString())
End If
Next

Hope that help.
