Hi

The below code is to read the random line from Test.txt

Hope with some modifications this can be helpful and solve your issue.

Code:
TextReader tr = new StreamReader(Request.PhysicalApplicationPath + "Test.txt");
            int nooflines = 0;
            while (tr.ReadLine()!=null)
            {
                nooflines++;
            }
            Random randnum = new Random();

            tr.Close();
            tr = new StreamReader(Request.PhysicalApplicationPath + "Test.txt");


            int rnd = randnum.Next(0,nooflines);
            int i=0;
            string temp;
            while (( temp = tr.ReadLine()) !=null) 
            {

                if (i==rnd)
                {
                    ShowMsg.Text=temp;
                    break;
                }
                i++;

            }
            tr.Close();
