C# 调用java webservice

java端的webservice 是用axis1.4 和tomcat5.5 做的
下面是wsdl文件
<?xml version="1.0" encoding="UTF-8" ?> 
<wsdl:definitions targetNamespace="http://localhost:8080/axis/services/CompletObject" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://localhost:8080/axis/services/CompletObject" xmlns:intf="http://localhost:8080/axis/services/CompletObject" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<wsdl:types>
<schema targetNamespace="http://localhost:8080/axis/services/CompletObject" xmlns="http://www.w3.org/2001/XMLSchema">
  <import namespace="http://schemas.xmlsoap.org/soap/encoding/" /> 
 <complexType name="UserInfo">
 <sequence>
  <element name="age" type="xsd:int" /> 
  <element name="birthDay" nillable="true" type="xsd:date" /> 
  <element name="name" nillable="true" type="soapenc:string" /> 
  <element name="password" nillable="true" type="soapenc:string" /> 
  </sequence>
  </complexType>
  </schema>
  </wsdl:types>
  <wsdl:message name="getUserInfoRequest" /> 
 <wsdl:message name="getUserInfoAllInfoRequest">
  <wsdl:part name="info" type="impl:UserInfo" /> 
  </wsdl:message>
 <wsdl:message name="getUserInfoResponse">

  <wsdl:input message="impl:getUserInfoAllInfoRequest" name="getUserInfoAllInfoRequest" /> 
  <wsdl:output message="impl:getUserInfoAllInfoResponse" name="getUserInfoAllInfoResponse" /> 
  </wsdl:operation>
 <wsdl:operation name="getUserInfo">
  <wsdl:input message="impl:getUserInfoRequest" name="getUserInfoRequest" /> 
  <wsdl:output message="impl:getUserInfoResponse" name="getUserInfoResponse" /> 
  </wsdl:operation>
  </wsdl:portType>
 <wsdl:binding name="CompletObjectSoapBinding" type="impl:CompletObject">
  <wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" /> 
 <wsdl:operation name="getUserInfoAllInfo">
  <wsdlsoap:operation soapAction="" /> 
 <wsdl:input name="getUserInfoAllInfoRequest">
  <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://test" use="encoded" /> 
  </wsdl:input>
 <wsdl:output name="getUserInfoAllInfoResponse">
  <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:8080/axis/services/CompletObject" use="encoded" /> 
  </wsdl:output>
  </wsdl:operation>
 <wsdl:operation name="getUserInfo">
  <wsdlsoap:operation soapAction="" /> 
 <wsdl:input name="getUserInfoRequest">
  <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://test" use="encoded" /> 
  </wsdl:input>
 <wsdl:output name="getUserInfoResponse">
  <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:8080/axis/services/CompletObject" use="encoded" /> 
  </wsdl:output>
  </wsdl:operation>
  </wsdl:binding>
 <wsdl:service name="CompletObjectService">
 <wsdl:port binding="impl:CompletObjectSoapBinding" name="CompletObject">
  <wsdlsoap:address location="http://192.168.1.100:8080/axis/services/CompletObject" /> 
  </wsdl:port>
  </wsdl:service>
  </wsdl:definitions>现在问题是：
   1、我在java中调用是可以的，能够正确返回我定义的UserInfo对象
   2、我在vs 2005中添加web引用也能添加进来，但是添加进来后
      客户端代码：
        CompletObjectService cos = new CompletObjectService();  
        在这里就报错，异常信息
        未处理 InvalidOperationException 
        无法反射方法 CompletObjectService.getUserInfoAllInfo。总之  其实我的目的就是C# 和java webservice能传递自定义对象
