Complex data types with CSharp client

Hello All,

I am new to using NuSOAP, and have been making good
progress, but now I'm stuck.

I am access the webservice with a client app written
in CSharp. I have had sucess with simple functions
that pass strings, and return strings, but now need to
return complex data types.

I need to call a function which returns a list of
appointments in complex data form. I define the
following in the webservice:

$server->wsdl->addComplexType( 
     'Appointment', 
     'complexType', 
     'struct', 
     'all', 
     '', 
     array( 
        'first' =>
array('name'=>'first','type'=>'xsd:string'), 
        'last' =>
array('name'=>'last','type'=>'xsd:string'), 
        'modality' =>
array('name'=>'modality','type'=>'xsd:string'), 
        'procedure' =>
array('name'=>'procedure','type'=>'xsd:string')
        ) 
); 

$server->wsdl->addComplexType( 
     'AptArray', 
     'complexType', 
     'array', 
     'all', 
     'SOAP-ENC:Array', 
        array(array('ref'=>'SOAP-ENC:arrayType', 
                   
'wsdl:arrayType'=>'tns:Appointment' 
                 ) 
        ) 
); 

$server->register('getAppointments', 
     array('city'=>'xsd:string'),  // input 
     array('return'=>'tns:AptArray'),   // output 
     $NAMESPACE,                        // namespace 
     $NAMESPACE.'#getAppointments',     // soapaction 
     'rpc',                             // style 
     'encoded',                         // use 
     'Lists Appointments by city'       //
documentation 
); 

---

I use the wsdl.exe command line program with .NET to
generate a webservice proxy in C#.

It creates:

/// <remarks/>
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Web.Services.WebServiceBindingAttribute(Name="The_Worx_Group_Web_ServiceBinding",
Namespace="urn:theworxgroupwsdl")]
public class NVRAWebService :
System.Web.Services.Protocols.SoapHttpClientProtocol {
    
    /// <remarks/>
    public NVRAWebService() {
        this.Url =
"http://dev.nvra.com/phpworx/webservice.php";;
    }
    
    
    /// <remarks/>
   
[System.Web.Services.Protocols.SoapRpcMethodAttribute("urn:theworxgroupwsdl#getAppointments",
RequestNamespace="urn:theworxgroupwsdl",
ResponseNamespace="urn:theworxgroupwsdl")]
    [return:
System.Xml.Serialization.SoapElementAttribute("return")]
    public AptArray getAppointments(string city) {
        object[] results =
this.Invoke("getAppointments", new object[] {
                    city});
        return ((AptArray)(results[0]));
    }
    
    /// <remarks/>
    public System.IAsyncResult
BegingetAppointments(string city, System.AsyncCallback
callback, object asyncState) {
        return this.BeginInvoke("getAppointments", new
object[] {
                    city}, callback, asyncState);
    }
    
    /// <remarks/>
    public AptArray
EndgetAppointments(System.IAsyncResult asyncResult) {
        object[] results =
this.EndInvoke(asyncResult);
        return ((AptArray)(results[0]));
    }
}

/// <remarks/>
[System.Xml.Serialization.SoapTypeAttribute("AptArray",
"urn:theworxgroupwsdl")]
public class AptArray {
}

Now in my code, how do I interpret the return type?

For example:

try {
        NVRAWebService ws = new NVRAWebService();

        ??????? = ws.getAppointments("mytown"); 

} catch (Exception ex) {
        MessageBox.Show(ex.ToString());
}

What class/data type can I use to receive the results
of the call, and how do I iterate through the results?

Thanks,

-Frank
