Turn to static problem, use a function, error: the underlying connection is closed: this remote name cannot be resolved

geminibo

I am doing a static function
  The function used is as follows, the master should be familiar with this function.
public static string GetHttpPageTest (string urllink)
{
WebResponse response = null;
Stream stream = null;
StreamReader reader = null;
// try
// {
HttpWebRequest request = (HttpWebRequest) HttpWebRequest.Create (urllink);
//request.Timeout=1000;
response = request.GetResponse ();
stream = response.GetResponseStream ();
string buffer = "", line;
reader = new StreamReader (stream, System.Text.Encoding.UTF8);
while ((line = reader.ReadLine ())! = null)
{
buffer + = line + "\r\n";
}
Ranch
//}
// catch
// {
// return "$ False $";
//}
// finally
// {
if (reader! = null) reader.Close ();
if (stream! = null) stream.Close ();
if (response! = null) response.Close ();
//}
return buffer;
}
I run locally, the address on the internet can get the corresponding html
But when I upload this program to a server on the network, it doesn't work.
The following error appears, which master to show, thank you
The underlying connection has been closed: this remote name cannot be resolved.

It should be that your server cannot explain this domain name,
If you can go to the terminal, go up and see if you can ping that domain name.
Or visit directly with IE, it should not be accessible.

The problem of network access by the server has nothing to do with the program.

Take a look
Is it possible that the server cannot be connected to the Internet?

You use try...catch to output the urllink requested when the error occurs, and then you see if the client can request the address. There are many reasons why the server cannot explain the address, one of which is that the address is blocked by our country.

Try another domain name...

How to configure it on the server? Is it necessary to open a port
