With download code, you may update increment counter to a database or file.

Steps:
1. When user clicks on button to download a file.
2. Read increment counter value from database or from file.
3. Increment by 1.
4. Write to a file or update to a database.

Well I presume that your files for downloading purpose are located in a folder named myfiles under web application root.

Write following code in Button's click event where file downloading process starts.

protected void Button1_Click(object sender, EventArgs e)
    {
       DownLoadFile("test.zip"); // This file is located under myfiles 
folder.
   }

Add the definition of DownLoadFile() function in your code section of your page.

void DownLoadFile(string filename)
    {
        string path = MapPath("~/files/" + filename);
        byte[] byte_array = System.IO.File.ReadAllBytes(path);

        Response.ClearContent();
        Response.ClearHeaders();

        Response.AddHeader("Content-Type", "application/octate-stream"); 
        Response.AddHeader("Content-Length", byte_array.Length.ToString()); 
        Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);

        Response.BinaryWrite(byte_array);
        Response.Flush();
        Response.End();

        /****
        *  Write your code to update counter value - (Database or file)
        ****/
    }

You have to read the value of counter.

The application variable is not persisted (saved). It will increment for the life of a session then go back to zero.

You can enable AWStats for your site.

This will geve you statistics about the pages viewd and other data like counts of file accessed etc.

You can enable this if your hosting supports this.
