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)
{

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;
}
