Linq/Lambda OrderBy Delegate for List of IP Addresses

Question

Given List ips = new List();

I need to sort the list of IP addresses in a logical order (i.e. \"192.168.0.2\" comes before \

Answer 1

This one is pretty elegant (and fail proof if you use TryParse):

var sorted2 = from ip in ips
              let addressBytes = IPAddress.Parse(ip).GetAddressBytes()
              orderby addressBytes[0], addressBytes[1], addressBytes[2], addressBytes[3]
              select ip;

The addressBytes array will have length 4 as long as it is only IP4 addresses. Otherwise you should account for the length...
