Implementation takes a host name string as a parameter, and returns the IP addresses in a comma-delimitd string. Note that a failed lookup throws a SocketException.
<lang csharp>
private string LookupDns(string s)
{
try
{
System.Net.IPHostEntry ip = System.Net.Dns.GetHostEntry(s);
string result = ip.AddressList[0].ToString();
for (int i = 1; i < ip.AddressList.Length; ++i)
result += ", " + ip.AddressList[i].ToString();
return result;
}
catch (System.Net.Sockets.SocketException se)
{
return se.Message;
}
}
</lang>

The included Indy components wrap GetAddressInfo.
