  1. POWSDL generated code not deserializing long in XML properly
    text
    copied!<p>I have been given a WSDL by one of our suppliers that contains the following:</p> <pre><code>&lt;xsd:element name="RegistrationResponse"&gt; &lt;xsd:complexType&gt; &lt;xsd:sequence&gt; &lt;xsd:element name="DateTimeStamp" type="xsd:dateTime" nillable="true"/&gt; &lt;xsd:element name="EchoData" type="xsd:string" nillable="true"/&gt; &lt;xsd:element name="TransactionTrace" type="xsd:long" nillable="true"/&gt; &lt;xsd:element name="ResponseCode" type="xsd:int" nillable="true"/&gt; &lt;xsd:element name="ResponseMessage" type="xsd:string" nillable="true"/&gt; &lt;xsd:element name="ClientAccNumber" type="xsd:long" nillable="true"/&gt; &lt;xsd:element name="BranchCode" type="xsd:int" nillable="true"/&gt; &lt;xsd:element name="HIN" type="xsd:long" nillable="true"/&gt; &lt;xsd:element name="EasyPayRef" type="xsd:long" nillable="true"/&gt; &lt;/xsd:sequence&gt; &lt;/xsd:complexType&gt; &lt;/xsd:element&gt; </code></pre> <p>However sometimes the response I get back from them will not contain all the fields. For example in this instance:</p> <pre><code> &lt;soapenv:Body&gt; &lt;tpw:RegistrationResponse&gt; &lt;DateTimeStamp&gt; 2012-04-02T19:10:41.4430564Z &lt;/DateTimeStamp&gt; &lt;EchoData/&gt; &lt;TransactionTrace&gt; 5418721751027669946 &lt;/TransactionTrace&gt; &lt;ResponseCode&gt; 25 &lt;/ResponseCode&gt; &lt;ResponseMessage&gt; Invalid Mobile Account Type &lt;/ResponseMessage&gt; &lt;ClientAccNumber/&gt; &lt;BranchCode/&gt; &lt;HIN&gt; 0 &lt;/HIN&gt; &lt;EasyPayRef/&gt; &lt;/tpw:RegistrationResponse&gt; &lt;/soapenv:Body&gt; </code></pre> <p>Now the code generated by the code in Visual Studio when adding a service reference does not like the fact that the ClientAccNumber is blank. The generated code looks as follows:</p> <pre><code>[System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://tpwebservice.x.com", Order=5)] [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified, IsNullable=true)] public System.Nullable&lt;long&gt; ClientAccNumber; </code></pre> <p>I get an 'Input was not in the correct format' exception when it tries to deserialize the response received from the server. What I'm thinking is that it sees a blank string and tries to parse a long out of it, which obviously fails. I tried to add minOccurs="0" to the wsdl which didn't help.</p> <p>How do I fix the wsdl, or the generated code, to solve this problem? Or is there something else I am missing?</p>
