Errors Deserializing Soap Response

[Artur Niesporek]

Hi guys,

when receiving a soap response posted back from a server i get the
following error when deserializing the soap message. The problem seems
to be with the item-collection of the nightlyrate-Array.

[InvalidCastExce ption: Cannot assign object of type
wsclient.res.ws qa.nightlyrate to an object of type
wsclient.res.ws qa.nightlyrate[].]

Microsoft.Xml.S erialization.Ge neratedAssembly .XmlSerializati onReader1.Re
ad6_nightlyrate array()

System.Xml.Seri alization.XmlSe rializationRead er.ReadReferenc ingElement(S
tring name, String ns, Boolean elementCanBeTyp e, String& fixupReference)

System.Xml.Seri alization.XmlSe rializationRead er.ReadReferenc ingElement(S
tring name, String ns, String& fixupReference)

[InvalidOperatio nException: There is an error in XML document (1,

System.Xml.Seri alization.XmlSe rializer.Deseri alize(XmlReader
xmlReader, String encodingStyle)
System.Xml.Seri alization.XmlSe rializer.Deseri alize(XmlReader
xmlReader)

Generated WSDL-Proxy:

[System.Xml.Seri alization.SoapT ypeAttribute("n ightly-rate-array",
"http://websvc.worldres .com/BookingService" )]
public class nightlyratearra y {
public nightlyrate[] item;
}

[System.Xml.Seri alization.SoapT ypeAttribute("n ightly-rate",
"http://websvc.worldres .com/BookingService" )]
public class nightlyrate {
public System.Double baseRate;
public System.Double tax;
public System.Double extraAdult;
public System.Double extraChild;
}

Corresponding WSDL-Document part:

<xsd:complexTyp e name="nightly-rate">
<xsd:all>
<xsd:element minOccurs="1" maxOccurs="1" name="baseRate"
type="xsd:doubl e"/>
<xsd:element minOccurs="1" maxOccurs="1" name="tax" type="xsd:doubl e"/>
<xsd:element minOccurs="1" maxOccurs="1" name="extraAdul t"
type="xsd:doubl e"/>
<xsd:element minOccurs="1" maxOccurs="1" name="extraChil d"
type="xsd:doubl e"/>
</xsd:all>
</xsd:complexType >
<xsd:complexTyp e name="nightly-rate-array">
<xsd:sequence >
<xsd:element minOccurs="0" maxOccurs="unbo unded" name="item"
nillable="true" type="ns1:night ly-rate"/>
</xsd:sequence>
</xsd:complexType >

Any hints?

Thanks Artur

Hi Artur,

DId you call a web service on the server? From the error message, It seems
it return a nightlyrate instead of nightlyrate[]. You may check the web
service with disco.exe to see what type it will return.

Yes i checked it. From my view the Webservice assumes
like you said an nightrate array. But unfortunatly the
array has only one item in it. May this be the error
why .net is complaining?

Hi Artur,

Can you post the WSDL file disco.exe geneated? Itmay give us more
information on this. Additionally, did you add the web refference from the
WSDL file?

You can have a look at the WSDL at this URL:

From the WSDL, the return XML data should be like:
...
<nightly-rate-array>
<nightly-rate>
<baseRate>... </baseRate>
<tax>...</tax>
<extraAdult>... </extraAdult>
<extraChild>... </extraChild>
</nightly-rate>
</nightly-rate-array>
...

However, from te error message, it only return from the web service:

<nightly-rate>
<baseRate>... </baseRate>
<tax>...</tax>
<extraAdult>... </extraAdult>
<extraChild>... </extraChild>
</nightly-rate>

Have you check with the XML data actually returned? Which is its actual
value?
