正则表达式实现批量更新再替换

需要给文件中1,2,3........106的key找出来+106 .

code 实现如下:

  static void Main(string[] args)
        {
            //string words = "INSERT [dbo].[ClientApiUrl] ([ClientUrlId], [ClientUrl], [ProtocolType], [RouteType], [MethodType], [ServiceName], [RowCreatedOn], [RowLastModifiedOn], [RowLastModifiedBy]) VALUES (1, N'/Security_v1/api/User/.*$', 1, 1, 1, N'Sensitech.Security_v1/WebAPI', CAST(N'2017-01-17T08:29:01.0366667+00:00' AS DateTimeOffset), CAST(N'2017-01-17T08:29:01.0366667+00:00' AS DateTimeOffset), N'&system')INSERT [dbo].[ClientApiUrl] ([ClientUrlId], [ClientUrl], [ProtocolType], [RouteType], [MethodType], [ServiceName], [RowCreatedOn], [RowLastModifiedOn], [RowLastModifiedBy]) VALUES (2, N'/Security_v1/api/User/.*/.*$', 1, 1, 1, N'Sensitech.Security_v1/WebAPI', CAST(N'2017-01-17T08:29:01.1366667+00:00' AS DateTimeOffset), CAST(N'2017-01-17T08:29:01.1366667+00:00' AS DateTimeOffset), N'&system')";
            string filePath = @"D:\ClientApiUrl.txt";
            StreamReader reader = new StreamReader(filePath, Encoding.Default);
            string content = reader.ReadToEnd();
            reader.Close();

            string pattern = @"(?<=,\s)\d+(?=,)";
            Regex r = new Regex(pattern);
            MatchEvaluator evaluator = new MatchEvaluator(NumberPlus);
            content = Regex.Replace(content, pattern, evaluator);

            StreamWriter write = new StreamWriter(filePath,false,Encoding.Default);
            write.Write(content);

            write.Close();
            
            
            Console.ReadKey();
        }
