  TextWriter overiding value issue

  Sep 04, 2011 10:46 PM|LINK

  basically the code gets executed each time the any page (that has masterpage) runs. at the moment the .txt gets created and it contains one line of data as it should - however, if i run masterpage again then it overides. how can i stop this?

   

  if (dt != null)
          {
              if (dt.Rows.Count > 0)
              {
                  //TextWriter writer = new StreamWriter(Server.MapPath("visitorlog.txt"));
                  TextWriter writer = new StreamWriter("C:\\web\\project\\visitor.txt");
                  writer.Write(DateTime.Now.ToString() + " | " + dt.Rows[0]["City"].ToString() + " | " + dt.Rows[0]["RegionName"].ToString() + " | " + dt.Rows[0]["CountryName"].ToString() + " | " + dt.Rows[0]["CountryCode"].ToString());
                  writer.Close();
              }
              else
              {
  
              }
          }

  { //TextWriter writer = new StreamWriter(Server.MapPath("visitorlog.txt")); TextWriter writer = new StreamWriter("C:\\web\\project\\visitor.txt"); writer.Write(DateTime.Now.ToString() + " | " + dt.Rows[0]["City"].ToString() + " | " + dt.Rows[0]["RegionName"].ToString() + " | " + dt.Rows[0]["CountryName"].ToString() + " | " + dt.Rows[0]["CountryCode"].ToString()); writer.Close(); }

  This help..?

  if(!File.Exists("C:\\web\\project\\visitor.txt"))
  
      {
                  //TextWriter writer = new StreamWriter(Server.MapPath("visitorlog.txt"));
                  TextWriter writer = new StreamWriter("C:\\web\\project\\visitor.txt");
                  writer.Write(DateTime.Now.ToString() + " | " + dt.Rows[0]["City"].ToString() + " | " + dt.Rows[0]["RegionName"].ToString() + " | " + dt.Rows[0]["CountryName"].ToString() + " | " + dt.Rows[0]["CountryCode"].ToString());
                  writer.Close();
              }

  ok - you can append to file by setting the append to true in constructor

  TextWriter writer = new StreamWriter("C:\\visitor.txt", true);
