Parse string and grab only certain data

[Prodian]

Im trying to parse a recv from a telnet session then only grab certain data.

Heres an example of the recv that Im storing into a string:

Internet 204.189.124.205 0 001a.a01f.4e5a ARPA Vlan122

The only part I want is the mac address which is in bold.

Im trying to parse it while running it into a for loop so when it gets to the 4th section it will store that in another string. But its not working, anybody have any ideas?

public static string ParseMac(string macOut)
        {
 
 
            for (int i = 0; i < 10; i++)
            {
                if (i == 4)
                {
                    char[] delimiterChars = { ' ' };
 
                    string[] outPut = macOut.Split(delimiterChars);
 
                    foreach (string s in outPut) { }
 
                }
              }
            return (s);
 
            }

You have the right idea, but your loops are in the wrong order.

If you only care about the fourth part, consider something like this

public static string ParseMac(string macOut)
{
   char[] delimiterChars = { ' ' };
   string[] outPut = macOut.Split(delimiterChars);
   //index is 0,1,2,3,etc so the "fourth" part is [3]
   string PartWanted = outPut[3];
}

Thanks for the help, thats working fine when theres one space between each word but on the telnet output it could be 1 space or 5 spaces. Anyway around this?

The split() has an overload to wipe out blank entries (which would happen if two or more spaces are together), use that and it should be ok.

I did this instead:

string macOut = "Internet      204.189.124.205   16  0000.0c07.ac01   ARPA Vlan101";
 
            Regex r = new Regex(" +");
            string [] splitString = r.Split(macOut);
 
            string PartWanted = splitString[3];

Thanks for the help.
