Hi Sudhir,

 

            I figured out the problem but don't really know how to solve
it.

            

            Looks like the wsdl.exe tool I'm using has a bug.  It
creates a two-dimensional string array if the wsdl has nested elements
that contains maxOccurs=unbounded.

            

            In my WSDL I have the elements defined as follows.

            

            <complexType name="RecordData">

                <sequence>

                    <element maxOccurs="unbounded" name="fieldNames"
nillable="true" type="xsd:string"/>

                    <element maxOccurs="unbounded" name="records"
nillable="true" type="tns:Record"/>

                </sequence>

            </complexType>

            

            <complexType name="Record">

                <sequence>

                    <element maxOccurs="unbounded" name="fieldValues"
nillable="true" type="xsd:string"/>

                </sequence>

            </complexType>

            

            In the service class, this structure is generated as
follows., observe that the records field is created as a string[][]
instead or Record[]

            

    /// <remarks/>

    [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl",
"2.0.50727.42")]

    [System.SerializableAttribute()]

    [System.Diagnostics.DebuggerStepThroughAttribute()]

    [System.ComponentModel.DesignerCategoryAttribute("code")]

 
[System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:ws.rsys.com")]

    public partial class RecordData {

        

        private string[] fieldNamesField;

        

        private string[][] recordsField;

        

        /// <remarks/>

        [System.Xml.Serialization.XmlElementAttribute("fieldNames",
IsNullable=true)]

        public string[] fieldNames {

            get {

                return this.fieldNamesField;

            }

            set {

                this.fieldNamesField = value;

            }

        }

        

        /// <remarks/>

        [System.Xml.Serialization.XmlArrayAttribute(IsNullable=true)]

        [System.Xml.Serialization.XmlArrayItemAttribute("fieldValues",
typeof(string))]

        public string[][] records {

            get {

                return this.recordsField;

            }

            set {

                this.recordsField = value;

            }

        }

    }

 

Thanks

Raghu

Hi Raghu,

 

Can u put your code (java and C#) here so that we can check and compare
them to find out the loop holes. 

 

Thanks & Best Regards,

Sudhir Sharma

Subject: [Axis2] Problem with C# client accessing a Web Service

 

Hi,

 

            I have a webservice developed using Axis2 1.3.  I wrote a
Java client to access this webservice and everything is working fine.

            

            Today I started writing a C# client to access the same
webservice.

            

            I've used the wsdl.exe tool that comes with Microsoft Visual
Studio to generate the client code and wrote my own class to access
methods in the web service.

            

            Now when I try to run the C# client, I'm getting the below
exception.

 

   at System.Xml.Serialization.Compiler.Compile(Assembly parent, String
ns, XmlSerializerCompilerParameters xmlParameters, Evidence evidence)

   at

xmlMappings, Type[] types, String defaultNamespace, Evidence evidence,
XmlSerializerCompilerParameters parameters, Assembly assembly, Hashtable
assemblies)

   at WSCSharpClient.TestResponsysWS.run()

Unable to generate a temporary class (result=1).

error CS0030: Cannot convert type 'string[]' to 'string'

error CS0029: Cannot implicitly convert type 'string' to 'string[]'

 

            Does anyone have an idea what the problem is or am I missing
anything else?

 

Thanks in Advance.

Raghu
