Regular Expression Problem

[Stevo]

I'm trying to parse the output of ipconfig /all to retrieve the first MAC address that is not part of a VM adapter and the second byte should not be 50. A sample return is as follows: I'm able to retrieve just the MAC addresses and I'm able to discard them if 50 is in the second byte, but how do I determine if the word 'VMware' is in the immediately preceding description field and if so, enforce that no match is made.

Thanks.

Regular Expression:
..{2}-(?!50).{2}-.{2}-.{2}-.{2}-.{2}

I'm trying to parse the output of ipconfig /all to retrieve the
first MAC address that is not part of a VM adapter and the
second byte should not be 50. A sample return is as follows:
I'm able to retrieve just the MAC addresses and I'm able to
discard them if 50 is in the second byte, but how do I determine
if the word 'VMware' is in the immediately preceding description
field and if so, enforce that no match is made.

Stevo,

You can get both the Description and Physical Address w/ one regex.

string re =
@"Description.*?:\s*(?<description>.*?)\r\n" +
".*?Physical Address.*?:\s*(?<MAC>.*?)\r\n";

// "text" contains the Windows IP Config text.
MatchCollection mc = Regex.Matches(text, re,
RegexOptions.Singleline);

string description;
string MAC;
foreach(Match m in mc)
{
description = m.Groups["description"].ToString();
MAC = m.Groups["MAC"].ToString();

if (Regex.IsMatch(description, "vmware", RegexOptions.IgnoreCase))
continue;

Console.WriteLine(description);
Console.WriteLine(MAC);
}


In a DOS prompt, this will print:

SiS 900 PCI Fast Ethernet Adapter
00-0A-E6-AD-4B-B7


Hope this helps.
