i am using this method to serialize this response :
Private Sub SerializeCollection(filename As String)
Dim Emps As createShipmentResponse = New createShipmentResponse()
' Note that only the collection is serialized -- not the
' CollectionName or any other public property of the class.
Dim x As XmlSerializer = New XmlSerializer(GetType(createShipmentResponse))
Dim writer As TextWriter = New StreamWriter(filename)
x.Serialize(writer, Emps)
writer.Close()
End Sub
but i am having this error : Illegal characters in path
what does that mean ? and how can i fix this ?

Answer 1

Your SerializeCollection() method expects a file path to serialize to a file. You're currently passing the contents of your response which is why it doesn't work.
If you haven't written the method yourself I think you've not found completely what you're looking for.
This is an example of how the method should be called:
SerializeCollection("C:\Users\Vincent\Desktop\Hello.bin") 'The extension doesn't need to be '.bin', but it's an example.
The method has currently no way of getting your response, for that you should add a second parameter.
As I'm not familiar with Soap serialization I'm afraid I cannot help you further.
