Hi All,
How to read the complex type data from WSDL in vb.net? I am using below code for same.I am getting 'Warning 1 Variable 'ct_BundleBalanceDetails' is passed by reference before it has been assigned a value. A null reference exception could result at runtime.' message. Please help me.
'
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Try
Dim wbService As New WEB_APIs.Service
Dim ct_BundleBalanceDetails As WEB_APIs_SCBF.BundleBalanceDetailsComplexType()
Response.Write("Calling BundleBalanceRequest <br>")
Dim ResponseCode As String = wbService.BundleBalanceRequest(WEB_APIs_SCBF.InterfaceSimpleType.WEB, "03189719", ct_BundleBalanceDetails)
Response.Write("<br> BundleBalanceResponse ")
Response.Write(ResponseCode)
Catch ex As Exception
Response.Write("<br> API call is failed <BR>" & ex.Message)
Finally
End Try
End Sub
End Class

If the BundleBalanceRequest just sets the ByRef parameter, you can either ignore the warning or set the variable to Nothing.
e.g.
Dim ct_BundleBalanceDetails As WEB_APIs_SCBF.BundleBalanceDetailsComplexType() = Nothing
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.

Hi Zac,
Thanks for reply.I am facing below mentioned error.
Please help me.
WSDL:
<xs:element name="BundleBalanceRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="Interface" type="tns:InterfaceSimpleType"/>
<xs:element name="MSISDN" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="BundleBalanceResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="ResponseCode" type="xs:integer"/>
<xs:element name="ResponseData">
<xs:complexType>
<xs:sequence>
<xs:element name="BundleBalanceDetails" type="tns:BundleBalanceDetailsComplexType" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
Code:
Try
Dim wbService As New WEB_APIs_SCBF.Service
Dim ct_BundleBalanceDetails As WEB_APIs_SCBF.BundleBalanceResponseResponseData
Response.Write("Calling BundleBalanceRequest
")
Dim ResponseCode As String = wbService.BundleBalanceRequest(WEB_APIs_SCBF.InterfaceSimpleType.WEB, "03189719", ct_BundleBalanceDetails)
Response.Write("
BundleBalanceResponse ")
Response.Write(ResponseCode)
Catch ex As Exception
Response.Write("
API call is failed
" & ex.Message)
Finally
End Try
Output:
Calling BundleBalanceRequest
API call is failed
There is an error in XML docuement (1,580).
