Hi Guys.

I try to read a web page but it does not works.
Here is code from internet:

C#

using System.Net;
using System.IO;
using System.Windows.Forms;

string result = null;
string url = "http://www.devtopics.com";
WebResponse response = null;
StreamReader reader = null;

try
{
 HttpWebRequest request = (HttpWebRequest)WebRequest.Create( url );
 request.Method = "GET";
 response = request.GetResponse();
 reader = new StreamReader( response.GetResponseStream(), Encoding.UTF8 );
 result = reader.ReadToEnd();
}
catch (Exception ex)
{
 // handle error
 MessageBox.Show( ex.Message );
}
finally
{
 if (reader != null)
  reader.Close();
 if (response != null)
  response.Close();
}

I tested with this url http://priceboard.fpts.com.vn/user/stock/hcm3/?s=31&rd=r15332110001
It is a Price Board. Content result is lack of content data.

Help me fix it.
Thanks in advanced!.

Dear john Simmons
Thank you very much for your replying.
I have test your code and it has the same result with pie of code i gave above.
I saved result to a html file on my hardisk and saw that it is lack of many data from webpage.

Try this:

C#

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream() );
StringBuilder builder = new StringBuilder();
do
{
    str = reader.ReadLine();
    if (!string.IsNullOrEmpty(str))
    {
        builder.Append(str);
    }
while(str != null);
