.net中的webservice代码
[WebMethod]
  public int power(int a)
  {    return a*a;  }
客户端代码：
Private Sub Command_Click()
Dim Serializer As SoapSerializer30
Dim Reader As SoapReader30
Dim ResultElm As IXMLDOMElement
Dim FaultElm As IXMLDOMElement
Dim Connector As SoapConnector30

Const SoapAction = "http://tempuri.org/power"
Const END_POINT_URL = "http://localhost/NoWSE/Service1.asmx"

Set Connector = New HttpConnector30
Connector.Property("EndPointURL") = END_POINT_URL
Connector.Connect
    
Connector.Property("SoapAction") = SoapAction
Connector.BeginMessage
    
    Set Serializer = New SoapSerializer30
    Serializer.Init Connector.InputStream
     Serializer.StartEnvelope
    Serializer.StartBody
    Serializer.startElement "power", "http://tempuri.org/"
          
    Serializer.startElement "a"
    Serializer.WriteString CStr(10)
    Serializer.endElement
    
    Serializer.endElement
    Serializer.EndBody
    Serializer.EndEnvelope
     Connector.EndMessage
        
    Set Reader = New SoapReader30
    Reader.Load Connector.OutputStream
    
    If Not Reader.Fault Is Nothing Then
        MsgBox Reader.FaultString.Text, vbExclamation
    Else
        Text2.Text = Reader.RpcResult.Text
    End If
    End Sub
结果应该返回100啊，怎么返回0呢。查看soap请求也没什么错：
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
    <SOAP-ENV:Envelope xmlns:SOAPSDK1="http://www.w3.org/2001/XMLSchema" xmlns:SOAPSDK2="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAPSDK3="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<SOAPSDK4:power xmlns:SOAPSDK4="http://tempuri.org/">
  <a>10</a>
</SOAPSDK4:power>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
为什么返回结果总是不对呢？
