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 
  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 = 10000;
            List<string> gotStrings = GetStreamMethod(filePath);
            //Console.WriteLine(string.Join("
", gotStrings.ToArray()));
            if (gotStrings != null)
            {
                int fileCount = 1;
                for (int i = 0; i < gotStrings.Count; i++)
                {
                    StringBuilder sb = new StringBuilder();
                    sb.AppendFormat("{0}
", ("'" + gotStrings[i].Trim() + "',"));
                    if (i + 1 < gotStrings.Count)
                    {
                        i++;
                    }
                    else
                    {
                        WriteStreamMethod(string.Format("d:\Document{0}.txt", fileCount), sb.ToString());
