c# - Adding multiple reminder - windows phone -

i have learned on how create reminder application website http://www.c-sharpcorner.com/uploadfile/f397b9/reminder-application-in-windows-phone-mango/ here allows add 1 reminder. make new reminder, previous overrided. how make able accept multiple reminders. below code:

void btnsave_click(object sender, routedeventargs e)     {         datetime _date = rdate.value.value;         timespan _time = rtime.value.value.timeofday;         _date = _date.date + _time;         string _content = titletbox.text;         if (_date < datetime.now)             messagebox.show("your time not match !\nplease enter again !");         else if (string.isnullorempty(_content))             messagebox.show("your task can't empty !\n please enter task !");         else         {              scheduledaction _oldreminder = scheduledactionservice.find("todoreminder"); if (_oldreminder != null)                 scheduledactionservice.remove(_oldreminder.name);             reminder _reminder = new reminder("todoreminder")             {                 begintime = _date,                 title = "reminder",                 content = _content,             };             scheduledactionservice.add(_reminder);             //messagebox.show("set reminder completed");         }     } 

code working expected, finding registered reminder, when exists, remove , register new 1 same name.

separate code simple method

 private void registerscheduleifnotexist(string name, string title, string content, datetime time)     {         scheduledaction currentreminder = scheduledactionservice.find(name);          if (currentreminder != null)         {             scheduledactionservice.remove(currentreminder.name);         }          var reminder = new reminder(name)         {             begintime = time,             title = title,             content = content,         };          scheduledactionservice.add(reminder);     } 

then call method unique names if not wish override existing reminder, e.g.with task1, task2

registerscheduleifnotexist("task1", "task 1 title", "task 1 content", datetime.now.addminutes(3));  registerscheduleifnotexist("task2", "task 2 title", "task 2 content", datetime.now.addminutes(5));
