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：

 using System;
 using System.Collections.Generic;
 using System.IO;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;
 using Newtonsoft.Json.Serialization;
 using Newtonsoft.Json.Linq;
 using Newtonsoft.Json.Converters;
 using Newtonsoft.Json.Utilities;
 using Newtonsoft.Json;

 namespace ConsolePro
 {
     public class FileHelper
     {
         #region txt \r\n  给txt 文本 批量加',' 作为sql查询条件
         public static void CreateSQLContidion()
         {
             var filePath = "D:\\rt.txt";
             int TotalCountInEveryFile = ;
             List<string> gotStrings = GetStreamMethod(filePath);
             //Console.WriteLine(string.Join("\n", gotStrings.ToArray()));
             if (gotStrings != null)
             {
                 int fileCount = ;
                 for (int i = ; i < gotStrings.Count; i++)
                 {
                     StringBuilder sb = new StringBuilder();
                     sb.AppendFormat("{0}\r\n", ("'" + gotStrings[i].Trim() + "',"));
                     if (i +  < gotStrings.Count)
                     {
                         i++;
                     }
                     else
                     {
                         WriteStreamMethod(string.Format("d:\\Document{0}.txt", fileCount), sb.ToString());
                         return;
                     }

                         if (i != gotStrings.Count - )
                         {
