Hi all
I written this below code

string url = ConfigurationManager.AppSettings["ApplicationRoot"].ToString() + "/ASPX/PreviewToWord.aspx?ProjectInventoryID=48&ProjectID=30";
// Prepare the web page we will be asking for
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.ContentType = "application/msword";
request.UserAgent = "Mozilla/4.0+(compatible;+MSIE+5.01;+Windows+NT+5.0";
// Execute the request
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
// We will read data via the response stream
Stream resStream = response.GetResponseStream();
// Write content into the MemoryStream
BinaryReader resReader = new BinaryReader(resStream);
MemoryStream docStream = new MemoryStream(resReader.ReadBytes((int)response.ContentLength));
Document doc = new Document(docStream );
// Save document

Here I am getting two errors one is : The current HttpRequest is unauthorised …

Thanks for your request.

  1. This error occurs because you is not authorized and server returns 401 error. You can try specifying Credentials for this request. See the following code snippet.
request.Credentials = new NetworkCredential("user", "password");

Or send the credentials from the current user context (the user that started the application).

request.Credentials = System.Net.CredentialCache.DefaultCredentials;
