我们如何在服务器上捕获 c# 中的错误

Question

So I have here a working code in my local machine.

What does is do is it will rename today's textfile.

Path

E:\\Rename

Textfiles:

WithdrawalConfirm20200305.txt

paymentpagecalls20200223.txt

Output:

WithdrawalConfirm20200305.1400.txt

paymentpagecalls20200223.1400.txt

where .XXXX is the time you run the program.

 public Form1()
        {
            InitializeComponent();
        }

            string dateandtimevar = System.DateTime.Now.ToString("HHmm");

        private void Form1_Load(object sender, EventArgs e)
        {

                string FolderPath = @"E:\Rename";
                DirectoryInfo di = new DirectoryInfo(FolderPath);

                var files = di.EnumerateFiles($"*{DateTime.Now.ToString("yyyyMMdd")}.txt")
                .ToList();



                foreach (var file in files)
                {

                    //Parsing files
                    var newFile = file.FullName.Substring(0, file.FullName.Length - 3);


                    // Append new date
                    newFile = newFile + DateTime.Now.ToString("HHmm") + ".txt";

                    //Rename
                    File.Move(file.FullName, newFile);

Now my problem is when deploying to win 2008 R2 server it doesn't show any errors but it won't rename the text file like it does on my local machine. What could be wrong ?

I already checked the file path and the file exist on the server.

You should check the file extension of the file and make sure if it is .txt if not change it in your desired extension.

For example:

var files = di.EnumerateFiles($"*{DateTime.Now.ToString("yyyyMMdd")}.log")

newFile = newFile + DateTime.Now.ToString("HHmm") + ".log";
