Question

I asked a similar question there but for curl and webclient.

I found the answer for curl:

How to ensure that webclient/curl process 503 error like they process 200

CURLOPT_FAILONERROR

I want something like that but for webclient rather than for curl

Answer 1

The way each question is asked, probably means this question is a duplicate of the one linked to in this question. In any case I provide the same answer here as I did there:

For WebClient you need to process the WebException.Response. E.g. this LINQPad query dumps the HTML provided by my web server’s “Not Found” error web page:

Dim wc = New System.Net.WebClient
Try 
  Dim rd = wc.DownloadData(New Uri("http://localhost/test"))
  rd.Dump
Catch Ex As System.Net.WebException
 Dim rs = Ex.Response
 Call (New StreamReader(rs.GetResponseStream)).ReadToEnd.Dump
End Try
