.NET Programmattic Form Post

Need to send XML doc in form post (vb.Net)

[AlphaChimp]

I need to send an XML doc in a form post programmatically . I need to create the form content including header information, post it to a remote server, and read the response from the remote server.

I would really benefit from a concise sample (in vb.NET) demonstrating how I might accomplish this task.

Try this function, it should work just pass xml as string

Protected Function UploadValues(ByVal xml As String) As String
Dim myWebClient As New WebClient
Dim URL As String = "put post url here"
Dim myNameValueCollection As New System.Collections.Specialized.NameValueCollection
myNameValueCollection.Add("xml", xml)
Try
Dim responseArray As Byte() = myWebClient.UploadValues(URL, "POST", myNameValueCollection)
UploadValues = Encoding.ASCII.GetString(responseArray)
'here is you stream from source
Catch ex As Exception
Return ex.Message
End Try
End Function

Thanks, tomasz. I am missing something key here because I cannot see a response. Where in your sample is the "POST" sent to the server?

Protected Function UploadValues(ByVal xml As String) As String
Dim myWebClient As New WebClient
Dim URL As String = "put post url here"
Dim myNameValueCollection As New System.Collections.Specialized.NameValueCollection
myNameValueCollection.Add("xml", xml)
Try
Dim responseArray As Byte() = myWebClient.UploadValues(URL, "POST", myNameValueCollection)
UploadValues = Encoding.ASCII.GetString(responseArray)
'here is you stream from source
Catch ex As Exception
Return ex.Message
End Try
End Function

you response is UploadValues

lblPostXMLResult.Text=UploadValues(myXMLstring)
