Save and play WCF messages

I want to store WCF messages in some store and read them later to play them again.

Several pieces of code are attached:
private void WriteMessage(Message message, string path)
{
FileStream fileStream = new FileStream(path, FileMode.Create);

using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter (fileStream))
{
using (XmlDictionaryReader reader = message.GetReaderAtBodyContents ())
{
message.WriteBodyContents (writer);
writer.Flush ();
}
}
}

private Message ReadMessage (string path)
{
using (FileStream fs = File.OpenRead (path))
{
using (XmlDictionaryReader reader = XmlDictionaryReader.CreateBinaryReader (fs, XmlDictionaryReaderQuotas.Max))
{
fs.Flush ();
Message message = Message.CreateMessage (reader, int.MaxValue, messageVersion);
return message.CreateBufferedCopy (int.MaxValue) .CreateMessage ();
}
}
}

the problem is that before storing the message, Message.ToString () returns the message string as it would like, the whole message, but after reading it, ToString () shows the body as "... stream" .. "and what it is.

please advise
Thanks a lot :-)

Note that in "WriteMessage" only the body is read and written when the message is wrapped in another message.
