void
Main()
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(
"http://csharpindepth.com/asd"
);
try
{
using
(Stream data = request.GetResponse().GetResponseStream())
{
using
(StreamReader reader =
new
StreamReader(data))
{
string
text = reader.ReadToEnd();
Console.WriteLine(text);
}
}
}
catch
(WebException ex)
{
HttpWebResponse response = (HttpWebResponse) ex.Response;
Console.WriteLine(
"Error code: {0}"
, response.StatusCode);
if
(response.StatusCode == HttpStatusCode.BadRequest)
{
using
(Stream data = response.GetResponseStream())
