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;
 12
 13 namespace ConsolePro
 14 {
 15     public class FileHelper
 16     {
 17         #region txt \r\n  给txt 文本 批量加‘,‘ 作为sql查询条件
 18         public static void CreateSQLContidion()
 19         {
 20             var filePath = "D:\\rt.txt";
 21             int TotalCountInEveryFile = 10000;
 22             List<string> gotStrings = GetStreamMethod(filePath);
 23             //Console.WriteLine(string.Join("\n", gotStrings.ToArray()));
 24             if (gotStrings != null)
 25             {
 26                 int fileCount = 1;
 27                 for (int i = 0; i < gotStrings.Count; i++)
