Question

I’m trying to create a method in C# to return a string of a web pages html content from the url. I have tried several different ways, but I am getting the error System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive.

The following works fine locally, but gets the above error when running on a remote server:

  public static string WebPageRead(string url)     {         string result = String.Empty;          WebResponse response = null;         StreamReader reader = null;          try         {             if (!String.IsNullOrEmpty(url))             {                 HttpWebRequest request = HttpWebRequest.Create(url) as HttpWebRequest;                 request.Method = 'GET';                 request.KeepAlive = false;                 request.ProtocolVersion = HttpVersion.Version10;                  response = request.GetResponse();                 reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);                 result = reader.ReadToEnd();             }         }         catch (Exception exc)         {             throw exc;         }         finally         {             if (reader != null)             {                 reader.Close();             }              if (response != null)             {                 response.Close();             }         }          return result;     }

Thanks for the responses, the problem was due to a DNS issue on the remote server! Just to confirm, I went with the following code in the end:

    public static string WebPageRead(string url)     {         string content = String.Empty;          if (!String.IsNullOrEmpty(url))         {             HttpWebRequest request = HttpWebRequest.Create(url) as HttpWebRequest;              if (request != null)             {                 request.Method = 'GET';                 request.KeepAlive = false;                 request.ProtocolVersion = HttpVersion.Version10;                  try                 {                     using (WebResponse response = request.GetResponse())                     {                         using (Stream stream = response.GetResponseStream())                         {                             using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))                             {                                 content = reader.ReadToEnd();                             }                         }                     }                 }                 catch (Exception exc)                 {                     throw exc;                 }             }         }                              return content;     }
