How can I parse/deserialize a MTOM/XOP response that I get from a web service using WCF? I have the response on disk. I have copied the response below:

Any help is much appreciated.
You can deserialize the response using the WCF classes, as I'll show below. But before we proceed, this MTOM is invalid - the parameter boundary
of the Content-Type
header is malformed. Since it contains the '?' character, it needs to be quoted (look at the MIME RFC, section 5.1, definition of token
).
Now, to deserialize it, you need to open the document with a MTOM reader - and XmlDictionaryReader.CreateMtomReader
will give you exactly that. With that reader created, you can pass it to the DataContractSerializer
to deserialize the object. The code below shows how this can be done.

this is a binary content; it could be anything but for simplicity I'm using text
