WCF同域动态绑定服务地址

此方法一般用于Web，部署环境经常变化导致IP经常变动

例子是Silveright调用同域WCF服务的方法

        WordGameServiceClient GetClient()
        {
            BasicHttpBinding basicbind = new BasicHttpBinding(BasicHttpSecurityMode.None);

            BinaryMessageEncodingBindingElement binE = new BinaryMessageEncodingBindingElement();
            CustomBinding bind = new CustomBinding(basicbind);
            bind.Elements.Add(binE);
            EndpointAddress address = new EndpointAddress(new Uri(Application.Current.Host.Source, "../Service/WordGameService.svc"));

            //也可以自定义绑定，需要和服务绑定对应
            //return new WordGameServiceClient(bind, address);
            return new WordGameServiceClient("CustomBinding_WordGameService", address);
           
        }
