I am trying to query some URL using WebClient
.
I have a collection which I loop through to get the QueryString
value, and build final URL, and then pass it on to client.
The very first time it gets executed well, I get proper response, however, when it goes in loop second time, I get the error:
System.Net.WebException --> The remote server returned an error: (403) Forbidden.
If I get response for very first time. Then I should get for rest of the collection too.
Any clue why? What I might be missing?
Below is the code snippet I am using.
using(System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:sample.text")) {
foreach(var f in fileCollections) {
strFinalURL = string.Empty;
strFinalURL = "someURL" + f; // f can be considered as querystring param value
try {
using(var client = new WebClient()) {
test = client.DownloadString(strFinalURL);
if (!test.Contains("somecondition")) {
file.WriteLine("");
}
}
} catch (System.Exception ex) {
Console.WriteLine(ex.Message);
}
}
}
