web services - Calling SOAP API with Complex Type in C# -

i'm new .net, apologize in advance if definition of problem not accurate.

i'm attempting consume soap web service , i'm having problem constructing complex type element called deliveryroutingrequestentries.

i have added wsdl using service reference, here part of wsdl:

<wsdl:operation name="validatedeliveryaddress">   <soap:operation soapaction="" style="document" />   <wsdl:input name="validatedeliveryaddress">     <soap:body use="literal" />   </wsdl:input>   <wsdl:output name="validatedeliveryaddressresponse">     <soap:body use="literal" />   </wsdl:output> </wsdl:operation>    <xs:complextype name="deliveryroutingrequestentries">     <xs:sequence>       <xs:element maxoccurs="unbounded" name="deliveryroutingrequestentry" type="tns:delroutingrequestentry" />     </xs:sequence>   </xs:complextype>   <xs:complextype name="delroutingrequestentry">     <xs:sequence>       <xs:element minoccurs="0" name="addressvalidationrequired" type="xs:boolean" />       <xs:element name="customer" type="tns:customer" />       <xs:element name="parcel" type="tns:parcel" />       <xs:element minoccurs="0" name="services" type="tns:services" />       <xs:element minoccurs="0" name="senderaddress" type="tns:senderaddress" />       <xs:element minoccurs="0" name="productcode" type="xs:decimal" />       <xs:element name="expecteddespatchdate" type="xs:date" />       <xs:element minoccurs="0" name="requireddate" type="xs:date" />       <xs:element minoccurs="0" name="countryoforigin" type="xs:string" />       <xs:element minoccurs="0" name="warehouseno" type="xs:decimal" />       <xs:element minoccurs="0" name="carriercode" type="xs:string" />       <xs:element minoccurs="0" name="deliverymethod" type="xs:string" />       <xs:element minoccurs="0" name="multiplepartsid" type="xs:string" />     </xs:sequence>   </xs:complextype> 

here attempt call validatedeliveryaddress:

using system; using system.collections.generic; using system.linq; using system.web; using system.web.ui; using system.web.ui.webcontrols; using hermeswebservice;  public partial class _default : system.web.ui.page {     protected void page_load(object sender, eventargs e)     {      }     protected void button1_click(object sender, eventargs e)     {         routingwebserviceclient objhermeswebservice = new routingwebserviceclient();         objhermeswebservice.clientcredentials.username.username = "abababab";         objhermeswebservice.clientcredentials.username.password = "abababab";          deliveryroutingrequest objroutingrequest = new deliveryroutingrequest();         objroutingrequest.clientid = "abab";         objroutingrequest.clientname = "abab";         objroutingrequest.userid = "ababab";         objroutingrequest.sourceofrequest = "ababab";          delroutingrequestentry objreqentry = new delroutingrequestentry();          customer objcust = new customer();         objcust.customerreference1 = "12345";          address objadr = new address();         objadr.streetname = "7 bridge street";         objadr.addressline1 = "london heathrow airport";         objadr.city = "london";         objadr.region = "hounslow";         objadr.postcode = "aba aba";         objadr.countrycode = "gb";          parcel objpcl = new parcel();         objpcl.weight = 100;         objpcl.length = 0;         objpcl.width = 0;         objpcl.depth = 0;         objpcl.girth = 0;         objpcl.combineddimension = 0;          objcust.address = objadr;         objreqentry.customer = objcust;         objreqentry.parcel = objpcl;          objroutingrequest.deliveryroutingrequestentries = objreqentry; (i receive error here stating: cannot implicitly convert type 'hermeswebservice.delroutingrequestentry' 'hermeswebservice.delroutingrequestentry[]')          var x = objhermeswebservice.validatedeliveryaddress(objroutingrequest);      } } 

the problem have can't add customer, address , parcel objroutingrequest can included in request.

hope makes sense, let me know if additional information needed.

(just move answer here:)
got error @ : objroutingrequest.deliveryroutingrequestentries = objreqentry;,
should pass array:
objroutingrequest.deliveryroutingrequestentries = new [] {objreqentry};
