DNS Networking

I currently have a Server and Client application written.

The client ues TCP/IP Sockets to connect through to the server via its IP addresses.

I recently ran into a situation that would require a change in this functionality. I need to use DNS name instead.

Does anyone have any code examples or links that can help me on this

This is what I have right now

try
{
//create a new client socket ...
m_socClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

System.Net.IPAddress remoteIPAddress = System.Net.IPAddress.Parse(IPADDY HERE);
System.Net.IPEndPoint remoteEndPoint = new System.Net.IPEndPoint(remoteIPAddress, PortNoHERE);

m_socClient.Connect(remoteEndPoint);
}
catch (SocketException se)
{
System.Diagnostics.EventLog.WriteEntry(this.ToString(),
"ERROR DURING CONNECT" + se.ErrorCode + ":: " + se.Message);
}

Did you try looking up the host name IP address using DNS?

I tried to put in what you listed above.

So far I see a error "A field initializer cannot reference the nonstatic field, method or property"

Can you show me what you tried?

I just tried again and was able to get a IP address

IPHostEntry hostInfo = Dns.GetHostEntry("PCNAME HERE");
// Get the IP address list that resolves to the host names contained in the
// Alias property.
IPAddress[] address = hostInfo.AddressList;
// Get the alias names of the addresses in the IP address list.
String[] alias = hostInfo.Aliases;

So do I just keep what I already have in place then above. Or is there another way

Bob Learned

If that works, you should go with that.
