我想在文件中写入 System.ServiceModel.Channels.Message 类型的请求的内容，即使由于 XML 异常而无法读取它。

例如：我调用request.CreateBufferedCopy(int.MaxValue);where request 是我收到的 Channels.Message 并返回以下错误：

System.Xml.XmlException: The token '>' was expected but found 'a'. Line 80, position 19.
   at System.Xml.XmlExceptionHelper.ThrowXmlException(XmlDictionaryReader reader, String res, String arg1, String arg2, String arg3)
   at System.Xml.XmlExceptionHelper.ThrowTokenExpected(XmlDictionaryReader reader, String expected, Char found)
   at System.Xml.XmlUTF8TextReader.ReadEndElement()
   at System.Xml.XmlUTF8TextReader.Read()
   at System.Xml.XmlBinaryWriter.WriteTextNode(XmlDictionaryReader reader, Boolean attribute)
   at System.Xml.XmlDictionaryWriter.WriteNode(XmlDictionaryReader reader, Boolean defattr)
   at System.ServiceModel.Channels.ReceivedMessage.OnWriteBodyContents(XmlDictionaryWriter writer)
   at System.ServiceModel.Channels.Message.OnWriteMessage(XmlDictionaryWriter writer)
   at System.ServiceModel.Channels.Message.OnCreateBufferedCopy(Int32 maxBufferSize, XmlDictionaryReaderQuotas quotas)
   at System.ServiceModel.Channels.Message.CreateBufferedCopy(Int32 maxBufferSize)

我希望能够将请求的内容写入文件中，以便查看实际问题。（这是一个简单的例子，但我想写这个文件可能还有其他原因）

我尝试使用 将我的请求转换为字节数组BinaryFormatter，但 Channels.Message 不可序列化。

这是我测试的请求，我接受了一个有效的肥皂请求并在末尾删除了一个“>” </controlActEvent：

            </queryByParameter>
        </controlActEvent
    </PRPA_IN1>
</s:Body>

但我想记录我收到的任何东西，所以我的例子并不重要。
