retrieving MAC address using C# question.

[Guest]

Hi,

This is the code I'm using to get MAC address..
-------------------------------------------------------------------------------------------
ManagementClass mc = new ManagementClass

("WIN32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
if((bool)mo["IPEnabled"] == true )
{
Console.WriteLine("MAC Address \t{0}", mo["MacAddress"].ToString());
mo.Dispose();
}
}
-----------------------------------------------------------------------------------------------

Execution of this code is taking about 4-5 seconds!!!!. Is this normal or
am I doing anything wrong.. is there any quicker way of finding MAC address
of
of a PC using C#.

Kindly let me know

Cheers,

Naveen.

("WIN32_NetworkAdapterConfiguration");

Try "Win32_NetworkAdapter"?

Since that retrieves less information, it might be faster. On my PC both
are reasonably fast.

No it's not normal, this should take less than a second.
Try running wbemtest.exe; connect to the root\cimv2 namespace and execute
the same query.
If this also takes 4-5 seconds you have some environmental problem like CPU
resources, memory resources etc.
What OS are you running this on?
