C# System.NullReferenceException NSoup

Question

for (int x = 0; x < 50; x++)
{
    NSoupClient.Connect("https://steamcommunity.com/gid/" + x)
               .UserAgent("Firefox")
               .Timeout(10000)
               .Get();
}

This piece of code will throw me this error (and it always stops when the int is 5):

An unhandled exception of type 'System.NullReferenceException' occurred in NSoup.dll

Answer 1

Seems You are not the only having the issue - https://nsoup.codeplex.com/workitem/8

Seems as an issue with library itself.

Answer 2

I fixed this using a WebClient to download the page.

using (WebClient wc = new WebClient())
{
    wc.Headers.Add("user-agent", "Mozilla/5.0 (Windows; Windows NT 5.1; rv:1.9.2.4) Gecko/20100611 Firefox/3.6.4");
    string html = wc.DownloadString(url);
    Document document = NSoupClient.Parse(html);
}
