SQL查询条件生成小工具

最近运维数据，经常遇到需要在sql条件中个In（'',''....）个字符串的情况，于是在网上找了个小工具改造一下，先用着；
效果如图：
  1 using System;
  2 using System.Collections.Generic;
  3 using System.IO;
  4 using System.Linq;
  5 using System.Text;
  6 using System.Threading.Tasks;
  7 using Newtonsoft.Json.Serialization;
  8 using Newtonsoft.Json.Linq;
  9 using Newtonsoft.Json.Converters;
 10 using Newtonsoft.Json.Utilities;
 11 using Newtonsoft.Json;

 15     public class FileHelper
 16     {
 17         #region txt 
  给txt 文本 批量加',' 作为sql查询条件
