    客户端->服务端—>客户端

    客户端代码:

    using (new OperationContextScope(client.InnerChannel))
               {
                   Message request = Message.CreateMessage(OperationContext.Current.OutgoingMessageHeaders.MessageVersion,
                       "http://Microsoft.ServiceModel.Samples/IService1/Sum", values);

                 请求

                   Message reply = client.Sum(request);

                  获取应答结果:

                   int sum = reply.GetBody<int>();
                   Console.WriteLine("Sum(1,2,3,4,5) = {0}", sum);

    服务端代码:

    public Message Sum(Message request)
           {
               int sum = 0;
               string text = "";

               //获取消息的body节点

               XmlReader body = request.GetReaderAtBodyContents();

               while (body.Read())
               {
                   text = body.ReadString().Trim();
                   if (text.Length > 0)
                   {
                       sum += Convert.ToInt32(text, CultureInfo.InvariantCulture);
                   }
               }
               body.Close();

               Message response = Message.CreateMessage(request.Version, "http://Microsoft.ServiceModel.Samples/IService1/SumResponse", sum);
               return response;

           }

    2.所有服务端代码

    public Message Sum(Message request)
           {
               int sum = 0;
               string text = "";

               //The body of the message contains a list of numbers which will be read directly using an XmlReader
               XmlReader body = request.GetReaderAtBodyContents();

               while (body.Read())
               {
                   text = body.ReadString().Trim();
                   if (text.Length > 0)
                   {
                       sum += Convert.ToInt32(text, CultureInfo.InvariantCulture);
                   }
               }
               body.Close();

               Message response = Message.CreateMessage(request.Version, "http://Microsoft.ServiceModel.Samples/IService1/SumResponse", sum);
               return response;

           }

           public Message GetFirst()
           {
               MessageVersion ver = OperationContext.Current.IncomingMessageVersion;
               return Message.CreateMessage(ver, "http://Microsoft.ServiceModel.Samples/IService1/GetFirstResponse");
           }

           public Message GetData()
           {
               Person p = new Person();
               p.name = "wang";
               p.age = 20;
               MessageVersion ver = OperationContext.Current.IncomingMessageVersion;
               return Message.CreateMessage(ver, "http://Microsoft.ServiceModel.Samples/IService1/GetDataResponse", p);
           }

           public Message GetDataStream()
           {
               FileStream stream = new FileStream(@"myfile.xml", FileMode.Open);
               XmlDictionaryReader xdr =
                      XmlDictionaryReader.CreateTextReader(stream,
                                  new XmlDictionaryReaderQuotas());
               MessageVersion ver =
                   OperationContext.Current.IncomingMessageVersion;
               return Message.CreateMessage(ver, "http://Microsoft.ServiceModel.Samples/IService1/GetDataStreamResponse", xdr);
           }


           public Message GetDataFault()
           {
               FaultCode fc = new FaultCode("Receiver");
               MessageVersion ver = OperationContext.Current.IncomingMessageVersion;
               return Message.CreateMessage(ver, fc, "Bad data", "http://Microsoft.ServiceModel.Samples/IService1/GetDataFaultResponse");
           }

       }

       [DataContract(Namespace = "http://schemas.datacontract.org/2004/07/WcfServiceLibrary1")]
       public class Person
       {
           [DataMember]
           public string name;
           [DataMember]
           public int age;
       }

    所有客户端代码:

              int[] values = { 1, 2, 3, 4, 5 };

                using (new OperationContextScope(client.InnerChannel))
                {
