Question

I want get picture of internet and insert into word .
I use this code .
MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart;
System.Net.WebRequest request =
System.Net.HttpWebRequest.Create("http://spsdev2:1009");
System.Net.WebResponse response = request.GetResponse();
ImagePart imagePart = mainPart.AddImagePart(ImagePartType.Jpeg);
//Send an HTTP request and get the image at the URL as an HTTP response
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(fileName);
WebResponse myResp = myReq.GetResponse();
//Get a stream from the webresponse
Stream stream = myResp.GetResponseStream();
I get error in myReq.GetResponse();
Error :The remote server returned an error: (401) Unauthorized.
Edit
This code work for me :)
myReq.UseDefaultCredentials = true;
myReq.PreAuthenticate = true;
myReq.Credentials = CredentialCache.DefaultCredentials;

Answer 1

I add credentials for HttpWebRequest.
myReq.UseDefaultCredentials = true;
myReq.PreAuthenticate = true;
myReq.Credentials = CredentialCache.DefaultCredentials;

Answer 2

Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?
Something like request.Credentials = new NetworkCredential("UserName", "PassWord");
Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;

Answer 3

The answers did help, but I think a full implementation of this will help a lot of people.
using System;
using System.Collections.Generic;
using System.IO;
using System.Net;
using System.Text;
namespace Dom
{
class Dom
{
public static string make_Sting_From_Dom(string reportname)
{
try
{
WebClient client = new WebClient();
client.Credentials = CredentialCache.DefaultCredentials;
// Retrieve resource as a stream
Stream data = client.OpenRead(new Uri(reportname.Trim()));
// Retrieve the text
StreamReader reader = new StreamReader(data);
string htmlContent = reader.ReadToEnd();
string mtch = "TILDE";
bool b = htmlContent.Contains(mtch);
if (b)
{
int index = htmlContent.IndexOf(mtch);
if (index >= 0)
Console.WriteLine("'{0} begins at character position {1}",
mtch, index + 1);
}
// Cleanup
data.Close();
reader.Close();
return htmlContent;
}
catch (Exception)
{
throw;
}
}
