hello friend
i have a text file name url.txt contain lots of url, one url in a line.

now i want to get the content of each an every page which are open on the basis of those urls,

here is my code:

using System;
using System.IO;
using System.Net;
using System.Text;

class WebFetch
	static void Main(string[] args)
		// used to build entire input
		StringBuilder sb  = new StringBuilder();

		// used on each read operation
		byte[]        buf = new byte[8192];
        int counter = 0;
        string line;

        // Read the file and display it line by line.
        System.IO.StreamReader file =
           new System.IO.StreamReader("c:/wamp/www/isbn/url.txt");
        while ((line = file.ReadLine()) != null)
            // prepare the web page we will be asking for
            HttpWebRequest request = (HttpWebRequest)

            // execute the request
            HttpWebResponse response = (HttpWebResponse)

            // we will read data via the response stream
            Stream resStream = response.GetResponseStream();

            string tempString = null;
            int count = 0;
                // fill the buffer with data
                count = resStream.Read(buf, 0, buf.Length);

                // make sure we read some data
                if (count != 0)
                    // translate from bytes to ASCII text
                    tempString = Encoding.ASCII.GetString(buf, 0, count);

                    // continue building the string
            while (count > 0); // any more data to read?

            // print out page source

Remove the content of StringBuilder object after printing it on console window.


My Freind ,
after writing the HTML of current url on console window , you need to clear what is inside in "sb" string.
you can do that by using remover method of the string which takes 2 arguments("starting index","end index").
you put staring index to 0 and end index to the current length of the string using "sb.length" property.
like ,just before closing the file.
wirte: sb.remove(0,sb.length);
and you r done.
