Regular Expressions

[netbird]

Hi! Im wondering if someone could answer a really newbie question concerning regular expressions in c#. I have a string (stringPacket) containing an Ethernetpacket in hex and i want to put the first 6 characters in a variable called ethDestMac.

So far i have:

Regex regexPacket = new Regex(@"^(?<ethDestMac>[0-9a-f]{6})");
Match oMatch=regexPacket.Match(stringPacket);
ethDestMac = oMatch.Groups["ethDestMac"].ToString();

But that doesnt give me the correct answer. Would very much appreciate if someone could push me in the right direction on how to get my program to work.

Thanks!

You don't need a regular expression for this, you can do this by using normal string manipulation functions e.g.

string first6 = stringPacket.Substring(0,6);
