DataContractSerializer and deserializing web service response types
- by matra
Hi,
I am using calling web services and using WCF generated service-reference on the client. I have saved XML responses that are received from test service to disk (without SOAP envelope and body tags) I would like to load them from disk and create objects from them. Lets' take the following method from my web service:
SomeMethodResponse SomeMethod(SomeMethodRequest req)
I manually (through SOAP UI) save the response to disk to file, Sample response:
< SomeMethodResponse xmlns="http://myNamespace">
<SomeMember1>value</SomeMember1>
</SomeMethodResponse xmlns="http://myNamespace">
Then I try to deserialize the object from file using:
DataContractSerializer dcs =
new DataContractSerializer(typeof(SomeMethodResponse))
This fails – the serializer complains with the error, that it is expecting element in namespace 'http://schemas.datacontract.org/2004/07', but found element in 'http://myNamespace'.
Question: Why does the DataContractSerializer not use the namespace, that is declared on SomeMethodResponseType with XmlTypeAttribute(Namespace="http://myNamespace")?
I can work around this by explicitly providing the namespace and the root element to DataContractSerializer constructor. But then it fails with message similar to:
Error in line X position Y (last line of the XMLdocument). 'EndElement' 'SomeMethodResponse
from namespace 'httpmyNapespace’ is not expected.
Expecting element 'someNameField'.
SomeName is an element in the XSD that web service is using. It is also a property on the SomeMethodResponse type, backed by the private field called someNameField. It looks like DataContractSerializer is trying to deserialize the fields in addition to properties.
How can I deserailize XML that I have saved from disk and get back the object of same type that SomeMethod is returning?
Thanks,
Matra
