A simple Hit Counter function that will count how many visitors your website has reached. This function uses the StreamReader to read from a text file located in the root folder of your application, adn the StreamWriter to write into this file.

First, create a text file, name it as txtcounter.txt, and place it in the root folder or your application.
The GetStat() function will return the latest updated from the text file, and write new stat to it:

protected string  GetStat()
  {
      strFile = Server.MapPath("txtcounter.txt");
      sr = File.OpenText(strFile);
      counter = sr.ReadToEnd();
      sr.Close();
      i = int.Parse(counter) +1;
      counter=i.ToString();
      sw = File.CreateText(strFile);
      sw.Write(counter);
      sw.Close();
      return counter;
} 

Call this functin from the Form Load subroutine:

 
protected void Page_Load(object sender, EventArgs e)
   { 
             lbl.Text = GetStat();
   } 

Happy Coding!
