Get Just the Body of a WCf Message
提问by Jon
I'm having a bit of trouble with what should be a simple problem.
我在处理一个简单的问题时遇到了一些麻烦。
I have a service method that takes in a c# Message type and i want to just extract the body of that soap message and use it to construct a completely new message. I can't use the GetBody<>()method on the Message class as i would not know what type to serialise the body into.
我有一个接受 ac# Message 类型的服务方法，我只想提取该soap消息的正文并使用它来构造一个全新的消息。我不能GetBody<>()在 Message 类上使用该方法，因为我不知道将正文序列化为什么类型。
Does any one know how to just extract the body from the message? Or construct a new message which has the same body i.e. without the orginal messages header etc?
有谁知道如何从消息中提取正文？或者构造一个具有相同正文的新消息，即没有原始消息头等？

Not to preempt Yann's answer, but for what it's worth, here's a full example of copying a message body into a new message with a different action header. You could add or customize other headers as a part of the example as well. I spent too much time writing this up to just throw it away. =)
不是抢占 Yann 的答案，而是为了它的价值，这里有一个完整的示例，将消息正文复制到具有不同操作标头的新消息中。您也可以添加或自定义其他标题作为示例的一部分。我花了太多时间写这篇文章，只是把它扔掉。=)
class Program
{
[DataContract]
public class Person
{
[DataMember]
public string FirstName { get; set; }
[DataMember]
public string LastName { get; set; }
public override string ToString()
{
return string.Format("{0}, {1}", LastName, FirstName);
}
}
static void Main(string[] args)
{
var person = new Person { FirstName = "Joe", LastName = "Schmo" };
var message = System.ServiceModel.Channels.Message.CreateMessage(MessageVersion.Default, "action", person);
var reader = message.GetReaderAtBodyContents();
var newMessage = System.ServiceModel.Channels.Message.CreateMessage(MessageVersion.Default, "newAction", reader);
Console.WriteLine(message);
Console.WriteLine();
Console.WriteLine(newMessage);
Console.WriteLine();
Console.WriteLine(newMessage.GetBody<Person>());
Console.ReadLine();
}
}
回答by Yann Schwartz
You can access the body of the message by using the GetReaderAtBodyContents method on the Message:
您可以使用 Message 上的 GetReaderAtBodyContents 方法访问消息正文：
using (XmlDictionaryReader reader = message.GetReaderAtBodyContents())
{
string content = reader.ReadOuterXml();
//Other stuff here...
}
