        {
            SqlCommand cmd = new SqlCommand("SELECT TOP 1 * from Hitcount order by id desc", conn);
            SqlCommand command = new SqlCommand("insert into Hitcount(Name,Hit)values(@Name,@hit)", conn);

            conn.Open();

            SqlDataReader rdr = cmd.ExecuteReader();
            if (rdr.Read())
            {
                hit = Convert.ToInt32(rdr["hit"]);
                hit = hit + 1;
                rdr.Close();
            }

            command.Parameters.AddWithValue("@Name", "default");
            command.Parameters.AddWithValue("@hit", hit);
