web request in C#
say I am making a web request from my controller to another third party site to get some data.
sample below, example contrived for this question.
The third party site may be down and not return data. in such case, I would like to make couple of more tries and error out if it doesn't succeed at all.
Question - what's the best way to do this. so that if there is no response data in the first call , I try it say , two more times and
then error out.

var webClient = new WebClient();
var response = webClient.DownloadString("http://xyz.com/content);
if(response != null){
//do something
}
else {
//error couldn't retrieve data

Agree, a loop would do it. As commented, would suggest a sleep timer but you may also want to add some interaction on the front end (loading modal for example) so users aren't clicking around while you process attempts.
