Question

I have a C# Windows Forms app that launches a webpage based on some criteria.

Now I would like my app to automatically copy all the text from that page (which is in CSV format) and paste and save it in notepad.

Here is a link to an example of the data that needs to be copied:
http://www.wunderground.com/history/airport/FAJS/2012/10/28/DailyHistory.html?req_city=Johannesburg&req_state=&req_statename=South+Africa&format=1

Any Help will be appreciated.

Answer 1

http://msdn.microsoft.com/en-us/library/fhd1f0sw.aspx combined with http://www.dotnetspider.com/resources/21720-Writing-string-content-file.aspx

public static void DownloadString ()
{
    WebClient client = new WebClient();
    string reply = client.DownloadString("http://www.wunderground.com/history/airport/FAJS/2012/10/28/DailyHistory.html?req_city=Johannesburg&req_state=&req_statename=South+Africa&format=1");

    StringBuilder stringData = new StringBuilder();
    stringData = reply;  
    FileStream fs = new FileStream(@"C:\Temp\tmp.txt", FileMode.Create);
    byte[] buffer = new byte[stringData.Length];
    for (int i = 0; i < stringData.Length; i++)
    {
        buffer[i] = (byte)stringData[i];
    }
    fs.Write(buffer, 0, buffer.Length);
    fs.Close();
}

Edit Adil uses the WriteAllText method, which is even better. So you will get something like this:

WebClient client = new WebClient();
string reply = client.DownloadString("http://www.wunderground.com/history/airport/FAJS/2012/10/28/DailyHistory.html?req_city=Johannesburg&req_state=&req_statename=South+Africa&format=1");
System.IO.File.WriteAllText (@"C:\Temp\tmp.txt", reply);
