WebClient class is throwing exception

Hi,

Iam trying to use WebClient class under system.net namespace to download
files from internet via http. For that iam using DownloadFile method. But
when ever iam trying to download any file iam getting the error “"The
underlying connection was closed: Unable to connect to the remote server”. My
computer is behind proxy. If iam trying to open this image via browser then
it is working.

I am pasting my code below.

string remoteUri = "http://www.deepson.com/images/";
string fileName = "uc2_large08.jpg", myStringWebResource = null;
WebClient myWebClient = new WebClient();
myStringWebResource = remoteUri + fileName;
Response.Write("<hr>Downloading File "+ fileName + " from "+
myStringWebResource );
myWebClient.DownloadFile(myStringWebResource,"C:\\ inetpub\\wwwroot\\TestWebApp\\Downloaded\\"+fileNa me);

Response.Write("<hr>Successfully Downloaded File "+ fileName +" from "+
myStringWebResource);

When I am executing this code the file is created with 0 KB size but when
the error comes it is deleted automatically.

I think you've already answered your own question. You need to set up
your browser credentials for the connection:

WebProxy ProxyObject = new WebProxy("http://194.3.3.60:80" , true);
NetworkCredential cred = new NetworkCredential("User","password");
ProxyObject.Credentials=cred;
GlobalProxySelection.Select=proxyObject ;
