How to create a WCF Message object from SOAP response XML

Question

In order to unit test a class for handling WCF responses, I snagged an actual Message Response using Message.ToString() so that I don't have to actually make the WCF call (thus making it an integration test rather than a unit test). How do I re-construct a Message object based on that SOAP XML that comes from the Message.ToString() output, or is it even possible? I don't know which Message.CreateMessage() overloads addresses this situation.

Here's the result of the Message.ToString():

So, how do I construct a Message out of that?

Answer 1

If you have the whole envelope of a message, you can create the Message object by using the overload Message.CreateMessage(XmlDictionaryReader, int, MessageVersion). Create a XmlDictionaryReader over the contents of the message by using a code similar to this one:

var bytes = Encoding.UTF8.GetBytes(theMessageString);
var reader = XmlDictionaryReader.CreateTextReader(bytes, XmlDictionaryReaderQuotas.Max);

Now, the message you have has some timestamps, is encrypted and signed. It's possible that once you pass it to WCF, it will be invalid...
