copying a webpage toa local file using c#
Hi all,
I am developing a windows form where a .csv file needs to be accessed from the net and dump its contents in database.
Since the site does not have downloading option ,i am only left with an option to copy the contents of the .csv file when it is displayed as webpage.
For this i am using the following code,


HttpWebRequest objWebReq =(HttpWebRequest)WebRequest.Create("http://www.yoursite.com");
HttpWebResponse objWebResp = (HttpWebResponse)objWebReq.GetResponse();
StreamReader objStream = new StreamReader(objWebResp.GetResponseStream(), System.Text.Encoding.ASCII);
//read the data
string sResp = objStream.ReadToEnd();

if (sResp.Length > 0)

{
FileStream fsout = new
FileStream("myfile.txt", FileMode.Create, FileAccess.ReadWrite);
StreamWriter sw = new StreamWriter(fsout);
sw.Write(sResp);
}

it works fine ,but the problem is it does not copy the whole webpage.

i tried using stringbuilder to copy the stream but no use.


please anyone help me with this

Are you closing your StreamWriter? I don't see sw.Close(). This is necessary to flush the buffer to disk.

Minimally, the objWebResp should be closed as well. The objWebResp is rather important because by default your application can only open two simultaneous connections to another machine (configuration/system.net/connectionManagement in the app.config file). I'd recommend the "using" keyword to ensure proper cleanup even if an exception occurs.

using(HttpWebResponseobjWebResp=(HttpWebResponse)objWebReq.GetResponse())
{
//Codehere.
}
