Question

我想将所有银行编号的编号写入实际文件。不是控制台版本。但我没有看到文件系统中的实际文件。如何将数字写入文件系统？

我有这个：

static void Main(string[] args)
        {



            string path = @"G:\Folder";

            //string fileName = string.Format("{0}{1}-", part[0], part[part.Count - 1]);
            var bans = BankAcoutNumbers.BANS;          
            const int MAX_FILES = 10;
            const int BANS_PER_FILE = 10;
            int bansCounter = 0;
            var part = new List<int>();
            //string fileName = string.Format("{0}-{1}", part[0], part[part.Count - 1]);

            var maxNumberOfFiles = 10;
            Stopwatch timer = new Stopwatch();



                var fileCounter = 0;

                if (!Directory.Exists(path))
                {
                   DirectoryInfo di = Directory.CreateDirectory(path);
                }

                //var destiNationFile = new StreamWriter(string.Format(fileName, fileCounter + 1));
                try
                {

                    // foreach (var bank in BankAcoutNumbers.BANS.Take(100))
                    //{


                    while (fileCounter <= maxNumberOfFiles)
                    {
                        timer.Start();
                        foreach (var bank in BankAcoutNumbers.BANS)
                        {

                               break;



                                //lineCounter = 0;
                                //destiNationFile.Flush();

            System.Console.WriteLine("Press any key to exit.");
            System.Console.ReadKey();
        }

好。我试过这个并在光盘c得到以下文件：42346465-456456465,456365465-456456465,456456465-456365465,456456465-456465,456465-42346465。文件内部也是我发送给他们的内容。

试试这段代码：
另请注意为了演示目的，我制作了类BankAcoutNumbers ，其成员BANS
