How to Log Conversation?

Create a textfile inside your application say "Log.txt";

System.IO.StreamWriter objWriter;//Declare this as public.

string LOG_FILE_NAME; //Declare this as public.

protected void Page_Load(object sender, EventArgs e)

{

  LOG_FILE_NAME = Server.MapPath("Log.txt");

}

Now you will be knowing what will be the conversation between server and client. Put this in a string and call it in the following function inside the proper event handler.

string strMessage ="";//assign the conversation here

WriteLogMessage (strMessage);

public void WriteLogMessage(string strMessage)

    {

        try

        {

            if (System.IO.File.Exists(LOG_FILE_NAME) == true)

            {

                objWriter = System.IO.File.AppendText(LOG_FILE_NAME);

            }

            else

            {

                objWriter = System.IO.File.CreateText(LOG_FILE_NAME);

            }

            objWriter.Write(strMessage + Environment.NewLine);

        }

        catch (Exception ex)

        {

        }

        finally

        {

            objWriter.Flush();

            objWriter.Close();

        }

    }
