        con.Open();
        MySqlCommand cmd = new MySqlCommand("Insert into User_Details(User_ID,First__Name, Last_Name, Age, Gender, Country, About_User)values(@User_ID,@First__Name, @Last_Name, @Age, @Gender, @Country, @About_User)", con);

        cmd.Parameters.Add(new MySqlParameter("@User_ID",1));
        cmd.Parameters.Add(new MySqlParameter("@First_Name", txtFirstName.Text));
        cmd.Parameters.Add(new MySqlParameter("@FLast_Name", txtLastName.Text));

        cmd.Parameters.Add(new MySqlParameter("@About_User", txtUserDescription.Text));
        cmd.ExecuteNonQuery();
