2020.04.23. 수업내용 - json 파일 읽고 쓰기(불러오기, 저장하기) 3, 파일 2개 연습

 

 

오늘 배운 테이블 2개를 불러오는 방법과 선생님께서 카페에 올려주신 코드를 참고했습니다.

 

 

엑셀데이터

 

1) achievement_data

 

2) reward_data

2. AchievementData class

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace Study_015
{
    class AchievementData
    {
        public int id;
        public string name;
        public string desc;
        public int reward_id;
        public int reward_amount;
        public int goal;
    }
}

 

 

4. GameInfo class

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace Study_015
{
    class GameInfo
    {
        public Dictionary<int, AchievementInfo> dicAcievementInfo;
        public GameInfo()
        {
            this.dicAcievementInfo = new Dictionary<int, AchievementInfo>();
        }
    }
}
 

 

 

5. AchievementInfo class

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace Study_015
{
    class AchievementInfo
    {
        public int id;
        public int count;
 
        public AchievementInfo(int id, int count)
        {
            this.id = id;
            this.count = count;
 
        }
    }
}
 

 

 

6. 결과값

 

1) 처음 실행하고 업적을 1개 수행했을 때

 

 

2) 다시 실행해서 출력만 했을 때

 

 

3) 저장 파일이 없을 때(신규 유저 일때)
