Question

I’ve issue with access to property of my generated class.

This is my xml:

<?xml version="1.0" encoding="UTF-8"?>
<e:Envelope xmlns:e="http://www.w3.org/2003/05/soap-envelope"
 xmlns:w="http://schemas.xmlsoap.org/ws/2004/08/addressing"
 xmlns:d="http://schemas.xmlsoap.org/ws/2005/04/discovery"
 xmlns:dn="http://www.onvif.org/ver10/network/wsdl">
  <e:Header>
    <w:MessageID>uuid:84ede3de-7dec-11d0-c360-f01234567890</w:MessageID>
    <w:To e:mustUnderstand="true">urn:schemas-xmlsoap-org:ws:2005:04:discovery</w:To>
    <w:Action mustUnderstand="true">
      http://schemas.xmlsoap.org/ws/2005/04/discovery/Probe
    </w:Action>
  </e:Header>
  <e:Body>
    <d:Probe>
      <d:Scopes></d:Scopes>
      <d:Types>dn:NetworkVideoTransmitter</d:Types>
    </d:Probe>
  </e:Body>
</e:Envelope>

This is my generated xsd (one of three):

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="Envelope" targetNamespace="http://www.w3.org/2003/05/soap-envelope"
xmlns:mstns="http://www.w3.org/2003/05/soap-envelope"

          <xs:complexType>
            <xs:sequence>
              <xs:element ref="app1:MessageID" minOccurs="0" />
                  <xs:element ref="app1:To" />
              <xs:element ref="app1:Action" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
        <xs:element name="Body" msdata:Prefix="e">
          <xs:complexType>
            <xs:sequence>
              <xs:element ref="app2:Probe" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:choice>
    </xs:complexType>
  </xs:element>
</xs:schema>

I’ve no problem with Deserialization, it created proper class, but I don’t know, how to access to properties.
I was trying something like that:

PROBE.Envelope env = PROBE.Envelope.Deserialize(xmlString);
env.Items[0].MessageID = "xxxxxxxxxxx";

but it is wrong.

(Error 33 ‘object’ does not contain a definition for ‘MessageID’ and no extension method ‘MessageID’ accepting a first argument of type ‘object’ could be found (are you missing a using directive or an assembly reference?))

I’m including link to picture for better understanding of class structure.
I will be grateful for any advice, thank.

Answer 1

For some reason your Items property is of type object, but it should be EnvelopeHeader. Check your xsd file if you have defined all types correctly.

Or you can cast:

  ((EnvelopeHeader)env.Items[0]).MessageID = "xxxxxxxxxxx";
