Can't get web html code: System.Net.WebException: 'The remote server returned an error: (403) Forbidden.

Question

My problem is that I can't get specific website html code and I get this error: 'System.Net.WebException: 'The remote server returned an error: (403) Forbidden.'

My code is simple:

using (WebClient client = new WebClient())
        {
            string htmlCode = client.DownloadString("http://isbnsearch.org/isbn/");
            MessageBox.Show(htmlCode);
        }

When I try using other website like Google everything works perfectly, but with this website I can't reach it.

Is there any solution to fix this? Thanks

Answer 1

well as you dont have access to isbnsearch.org, so you can just catch the error and avoid your app break down, but can not solve it.

using (WebClient client = new WebClient())
        {
            try
            {
                 string htmlCode = client.DownloadString("http://isbnsearch.org/isbn/");
                 MessageBox.Show(htmlCode);
            }
            catch (Exception e)
            { 
                 MessageBox.Show(e.Message);
            }
        }

Found solution to get over this error:

        string url = "https://www.isbnsearch.org/";

        using (HttpClient client = new HttpClient())
        {
            using (HttpResponseMessage response = client.GetAsync(url).Result)
            {
                using (HttpContent content = response.Content)
                {
                    string result = content.ReadAsStringAsync().Result;
                    MessageBox.Show(result);
                }
            }
        }
