excel转json工具的制作(C#语言)

时间:2024-05-22 00:04:20

最近在做一个火炬之光的技能系统的demo,需要用到配置表工具。

&在网上没有找到让自己满意的工具&自己感兴趣,

so自己做了一个。

我使用的C#语言,用了网上的SimpleJSON工具脚本来做的,下面直接上代码:

界面代码(ps.注释掉的部分是生成对应代码的类,但感觉目前写的不好,就不上传了。。。)

 using System;
 using System.Collections.Generic;
 using System.Windows.Forms;

 namespace ConfigTool
 {
     public partial class Form1 : Form
     {
         private string excelPath;
         private string jsonPath;
         private string codePath;

         public Form1()
         {
             InitializeComponent();
             InitPath();
         }

         private void InitPath()
         {
             excelPath = Tool. GetPath() + "ConfigExcel";
             jsonPath = Tool.GetPath() + "Assets\\Resources\\Config";
             //codePath = Tool.GetPath(5) + "Assets\\Scripts\\Config";
             folderPath.Text = excelPath;
         }

         private void createJsonAndCode_Click(object sender, EventArgs e)
         {
             ExcelToJson etoJson = new ExcelToJson(excelPath, jsonPath);
             etoJson.CreateJsonFiles();
             fileNum.Text = etoJson.GetFileCount().ToString();

             //AutoCreateCode createCode = new AutoCreateCode(codePath, etoJson.JsonDic);
             //createCode.CreateCodeFiles();
         }
     }
 }

工具代码

 using System;
 using System.IO;

 namespace ConfigTool
 {
     public static class Tool
     {
         /// <summary>
         /// 创建文件
         /// </summary>
         /// <param name="_path">文件路径(包含文件名及其后缀)</param>
         /// <param name="_content">文件存储的内容</param>
         public static void CreateFile(string _path, string _content)
         {
             FileStream file = new FileStream(_path, FileMode.Create, FileAccess.Write);
             StreamWriter writer = new StreamWriter(file);
             writer.WriteLine(_content);
             writer.Close();
             file.Close();
             Console.WriteLine(string.Format("生成{0}", _path));
         }

         /// <summary>
         /// 删除指定文件夹下的子文件(不含子文件夹)
         /// </summary>
         /// <param name="_folderPath">文件夹路径</param>
         public static void ClearFiles(string _folderPath)
         {
             Console.WriteLine("开始删除文件,文件夹目录为" + _folderPath);
             if (!Directory.Exists(_folderPath))
             {
                 Console.WriteLine("指定的文件路径不存在");
                 return;
             }
             var files = Directory.GetFiles(_folderPath);
             foreach (var a in files)
             {
                 File.Delete(a);
             }
             Console.WriteLine("删除完成");
         }

         /// <summary>
         /// 获取当前exe的上层几层路径
         /// </summary>
         /// <param name="_upperNum">向上几级</param>
         /// <returns>路径</returns>
         public static string GetPath(int _upperNum)
         {
             string exePath = Directory.GetCurrentDirectory();
             string[] temp = exePath.Split("\\".ToCharArray());
             string path = string.Empty;
             ; i < temp.Length - _upperNum; i++)
             {
                 path += temp[i];
                 path += "\\";
             }
             return path;
         }
     }
 }

总结:

起始最核心的部分还是读取excel的部分,感觉应该对OleDbDataReader做一下说明:OleDbDataReader是一行一行来读取excel的读完一行再读下一行。我所写的确定表头,确定excel有效数据开始行就是利用这个性质来做的。

ps.刚开始理解不好,写了好几个无用的循环,后来反应过来改掉了(手动捂脸)。
