Exploring the SoapEnvelope Class in WSE2.0 - Body Property and SetBodyObject() method
(Page 5 of 5 )
A similar web service along the same lines as the above can be used to investigate and explore the Body property as well as the SetBodyObject() methods. Here the Body is a string, "Thing of beauty is a joy for ever." The SetBodyObject() method will set up the above "body" as the body of the envelope.
Public Function SetBdyObj() As String
Dim sen1 As New Microsoft.Web.Services2.SoapEnvelope
Dim strbdy As String
strbdy = "Thing of beauty is a joy for ever"
sen1.SetBodyObject(strbdy)
Try
Return sen1.Body.InnerXml
Catch ex As Exception
Return ex.Message
End Try
End Function
The web client would see the code shown in the next paragraph when he accesses this service and calls the SetBdyObj() function.
<string>
<string xmlns="http://tempuri.org/">Thing of beauty is a joy for
ever</string>
</string>
