读取WCF消息正文两次-“无法读取消息" [英] Read WCF Message body twice - "Message Cannot be read"

问题描述

我有一个WCF消息(Channels.Message)，我正在尝试使用.GetBody()提取正文.但是，我注意到我只能执行一次，并且如果我再次尝试使用"GetBody<>"，我将得到:此消息无法支持该操作，因为它已被读取."

I have a WCF Message (Channels.Message) which i'm trying to extract the body using .GetBody(). however, i notice that i can do it only once, and if i'm trying to use "GetBody<>" again, i'm getting :"This message cannot support the operation because it has been read."

有什么主意我该如何重新阅读邮件正文?

Any idea how can i re-read the message body?

谢谢

推荐答案

这是一篇关于您要在MSDN上尝试做的很好的文章.请参阅标题为将消息复制到缓冲区中的部分.它明确地讨论了必须多次访问消息正文.

Here is a pretty good article about what you are trying to do on MSDN. Please see the section titled Copying a Message into a Buffer. It explicitly talks about having to access the message body more than once.
