Exporting web service request to text file

[rbr]

Hello,

I am connecting to a webservice and creating a web reference in my
vb.net 1.1 app. When I create the request object I would like to
create an XML document to log the request and, susequently, the
response object to my local machine. Below is my code (Dummified of
course):

Dim WS As New WebService
Dim Req As New WebService.Request
Dim Resp As New
WebService.Response
WS.Timeout = 1000
Req.addressLine1 = address1
Req.addressLine2 = address2
Req.city = City
Req.firstName = FirstName
Req.lastName = LastName
Req.homePhoneNo = Phone
Req.state = State
Req.zipCode = Zip
'This is where I would like to write the request
(Req) to an XML document on the local machine
Resp = WS.csCreditScoreMain(Req)
'This is where I would like to write the response
(Resp) to an XML document on the local machine

Do you have any suggestions on how to achieve my desired end result?

Thanks in advance.
