WCF Self-Hosted ServiceHost Error with Multiple IP Addresses - web-services

Question

I'm self-hosting a web service using WCF. The host computer has multiple ethernet ports, so I am creating the ServiceHost with multiple URIs. When I create the service host, I get the following error:
"This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.
Parameter name: item"
Following is the code:
Uri[] uriSet = new Uri[ipList.Count];
for (int i=0; i<ipList.Count; i++)
{
string baseAddress = string.Format("http://{0}:{1}/mynamespace", ipList[i], myport);
uriSet[i] = new Uri(baseAddress);
}
host = new ServiceHost(webServiceType, uriSet);
ipList contains the list of IP addresses for the host computer.

Answer 1

You can use the special IP address 0.0.0.0 or just localhost to match any IP address for the local machine. Therefore, you should only need one base address URI, with either localhost or 0.0.0.0.
host = new ServiceHost(webServiceType, new Uri[] { new Uri("http://localhost:80/mynamespace") });
or
host = new ServiceHost(webServiceType, new Uri[] { new Uri("http://0.0.0.0:80/mynamespace") });
* where 80 is the port.
