System.Net.WebClient with Proxy and Credentials

[TheMaxx]

I try getting response from web site through proxy in my domain:

WebClient wc = new WebClient();
WebProxy wProxy = new WebProxy();

CredentialCache cc = new CredentialCache();
NetworkCredential nc = new NetworkCredential("myUsername", "myPassword",
"myDomain");
cc.Add("myProxy.domain.local", 8080, "Basic", nc);
// should this be: cc.Add("http://myProxy.domain.local", 8080, "Basic", nc);
?? got same error

wProxy.Credentials = cc;
wc.Proxy = wProxy;

string html = wc.DownloadString(new Uri("http://www.google.com/"));

MessageBox.Show(this, html);


I get error:
Message : Unable to connect to the remote server
InnerException : A connection attempt failed because the connected party did
not properly respond after a period of time, or established connection
failed because connected host has failed to respond


Is there a way to test just getting to proxy server and/or passing through
it?

Thanx.

This is one way that I do it:

WebProxy p = null;
string proxyAddressAndPort =
ConfigurationManager.AppSettings["proxy"];
string proxyUserName =
ConfigurationManager.AppSettings["proxyUserName"];
string proxyPassword =
ConfigurationManager.AppSettings["proxyPassword"];
ICredentials cred;
cred = new NetworkCredential(proxyUserName, proxyPassword);
p = new WebProxy(proxyAddressAndPort, true, null, cred);
WebRequest.DefaultWebProxy = p;

-That's for ASP.NET 2.0 , the last line for ASP.NET 1.1 would be like yours.

The IP address of the actual proxy server and port would look like:

10.10.128.3:8080

Thanx!
this worked for me!

now i'll try to find out what's wrong with my code.

WebProxy p = null;

ConfigurationManager.AppSettings["proxy"];
string proxyUserName =
ConfigurationManager.AppSettings["proxyUserName"];
string proxyPassword =

ICredentials cred;
cred = new NetworkCredential(proxyUserName, proxyPassword);
p = new WebProxy(proxyAddressAndPort, true, null, cred);
WebRequest.DefaultWebProxy = p;
