c# - Check if connect to remote server by Webclient -

i want check if project can connect remote server webclient in asp.net c# , something.

here code

webclient webclient = new webclient(); webclient.credentials = new system.net.networkcredential(username, password);  if (webclient.openread(url83).isconnected) // here, want check {     xmltextreader reader1 = new xmltextreader(webclient.openread(url83));     reader1.whitespacehandling = whitespacehandling.none;     //do } 

as described here best way check internet connectivity might like

try {     using (var client = new webclient())     using (var stream = client.openread(url83))     {         xmltextreader reader1 = new xmltextreader(stream);         reader1.whitespacehandling = whitespacehandling.none;         //do     } } catch (webexception ex) {      // occurs when error occur while reading network stream }
