Error sending client c # web service

Question

I am trying to use the Java web service, but getting an exception. System.InvalidCastException: cannot assign an object of type ValueArrayType to an object of type ValueArrayType []

I consume a third-party service, so I can’t change the service and was informed that they can use the service with php and java.

Array type is a complex type

<xsd:complexType name="ValueArrayType"> <xsd:sequence> <xsd:element name="ValueName" type="xsd:string"/> <xsd:element name="ValueType" type="xsd:string"/> <xsd:element name="ValueValue" type="xsd:string"/> </xsd:sequence> </xsd:complexType> 

This is an element in the response's DetailsType file that can have multiple occurrences, as it has max = unbound and is wrapped with a sequence attribute.

 <xsd:complexType name="DetailsType"> <xsd:sequence> <xsd:element name="Id" type="xsd:int"/> <xsd:element name="MobileName" type="xsd:string"/> <xsd:element name="ValueArray" type="tns:ValueArrayType" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType> 

I tried wsdll.exe and svrcutil.exe to try to create client code. ValueArrayType is defined in the generated code as an array.

 public ValueArrayType[] ValueArray { get { return this.valueArrayField; } set { this.valueArrayField = value; } } 

an example of the returned data.

 .... <Details xsi:type="tns:DetailsType"> <Id xsi:type="xsd:int">9999</Id> <ValueArray xsi:type="tns:ValueArrayType"> <ValueName xsi:type="xsd:string">Count</ValueName> <ValueType xsi:type="xsd:string">numeric</ValueType> <ValueValue xsi:type="xsd:string">11</ValueValue> </ValueArray> <ValueArray xsi:type="tns:ValueArrayType"> <ValueName xsi:type="xsd:string">Start</ValueName> <ValueType xsi:type="xsd:string">numeric</ValueType> <ValueValue xsi:type="xsd:string">31</ValueValue> </ValueArray> <ValueArray xsi:type="tns:ValueArrayType"> <ValueName xsi:type="xsd:string">A1</ValueName> <ValueType xsi:type="xsd:string">numeric</ValueType> <ValueValue xsi:type="xsd:string">23</ValueValue> </ValueArray> <ValueArray xsi:type="tns:ValueArrayType"> <ValueName xsi:type="xsd:string">A2</ValueName> <ValueType xsi:type="xsd:string">numeric</ValueType> <ValueValue xsi:type="xsd:string">0</ValueValue> </ValueArray> <ValueArray xsi:type="tns:ValueArrayType"> <ValueName xsi:type="xsd:string">X1</ValueName> <ValueType xsi:type="xsd:string">numeric</ValueType> <ValueValue xsi:type="xsd:string">0</ValueValue> </ValueArray> ..... 

If I change the client code to a public ValueArrayType ValueArray instead of an array, then the client works, but only the first ValueArray is received.

Tried suggestions from http://blogs.msdn.com/b/netcfteam/archive/2007/02/01/why-your-netcf-apps-fail-to-call-some-web-services.aspx .

Refresh
I created a WCF service with proxyclass generated from scvutil. When I use and check xml with WCFTestCLient.exe.

The array type is sent back as

 <ValueArray> <ValueArrayType> <ValueName>a</ValueName> <ValueType>string</ValueType> <ValueValue>1</ValueValue> </ValueArrayType> <ValueArrayType> <ValueName>a</ValueName> <ValueType>string</ValueType> <ValueValue>2</ValueValue> </ValueArrayType> </ValueArray> 

I assume that either the data sent does not match the WSDL, or an error appears in Cvvulil or System.ServiceModel.

Answer 1

Try to indicate the type of element inside the generated code.

 [XmlElement(ElementName = "ValueArray", Type = typeof(ValueArrayType), Namespace = "YourSchemaNamespace")] public ValueArrayType[] ValueArray { get { return this.valueArrayField; } set { this.valueArrayField = value; } } 

Additional information is available at MSDN.

Answer 2

The problem is caused by incorrect xsi: type values, which mislead WCF deserialization ( here) .

The workaround is to use OperationFormatUse.Literal instead of OperationFormatUse.Encoded for all operations.

Answer 3

Can you try something like this?

JavaServecie js = new JavaService ();

js.ValueArrayType arr = js.GetValues ​​(.....

if the class is public.
