wcf中的Message类

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

//Console.WriteLine(request.ToString());

Message reply = client.Sum(request);

//Console.WriteLine(reply.ToString());

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

// demo 1
                Message Reply1 = client.GetFirst();
                Console.WriteLine(Reply1.ToString());

// demo 2
                Message reply2 = client.GetData();
                Console.WriteLine(reply2.ToString());
                Person p = reply2.GetBody<Person>();
                Console.WriteLine(p.name + "    " + p.age.ToString());

// demo 3
                Message reply3 = client.GetDataStream();
                Console.WriteLine(reply3.ToString());
                FileStream stream = new FileStream(@"c:\log.xml", FileMode.Create);
                XmlDictionaryWriter xdw =
                    XmlDictionaryWriter.CreateTextWriter(stream);
                //reply1.WriteBodyContents(xdw);
                //reply1.WriteBody(xdw);
                reply3.WriteMessage(xdw);
                xdw.Flush();

// demo 4
                try
                {
                    Message reply1 = client.GetDataFault();
                    Console.WriteLine(reply1.ToString());
                }
                catch (FaultException e)
                {
                    Console.WriteLine(e.ToString());
                }

Console.WriteLine("=====================Demo5========================");
                // demo 5
                Message reply5 = client.GetDataStream();
                //Copy the message to a buffer.
                MessageBuffer mb = reply5.CreateBufferedCopy(65536);

//Log to a file.
                FileStream stream1 = new FileStream(@"C:\log.xml", FileMode.Append);
                mb.WriteMessage(stream1);
                stream1.Flush();

Console.WriteLine("=====================Demo6========================");
                Message reply6 = client.GetData();
                Console.WriteLine(reply6.ToString());
                foreach (MessageHeaderInfo mhi in reply6.Headers)
                {
                    Console.WriteLine(mhi.Name);
                }

}
