Hello

I've been doing a lot of surfing but couldn't find this out.

I want to connect to a WCF service but I have it's machine name (eg "DESK2"), rather than a DNS name.

C#

Uri uri = new Uri("http://localhost:8000/ServiceModelSamples/CalcService/CalculatorService");
			EndpointAddress adrs = new EndpointAddress(uri);
			CalculatorClient client = new CalculatorClient("WSHttpBinding_ICalculator", adrs);

Any ideas?

Many thanks
Ronny

Hi ronzu,
you can try it
I hope it's working fine.

IPAddress myIP = IPAddress.Parse(Request.UserHostName);
IPHostEntry GetIPHost = Dns.GetHostEntry(Request.UserHostName);
Response.Write(GetIPHost.HostName);

Thanks bojjaiah... but it didn't seem to work.

IPAddress.Parse from the documentation only accepts:
A string that contains an IP address in dotted-quad notation for IPv4 and in colon-hexadecimal notation for IPv6.

In any case it came up with FormatException when I just gave it a machine name ("DESK2").

I got the solution on another site.

The URI string does accept a machine name:

Uri uri = new Uri("http://DESK2:8000/ServiceModelSamples/CalcService/CalculatorService");

Sometimes the simplest thing actually works!

Cheers
Ronny
