C# 关闭应用程序后如何重命名当前文件名

Question

im coding on c#, im trying to make when the application closing the name of the file will be changed.

my base name in the application changing every 10ticks in timer random strings and i want it to take the last string and change the main name to that string.

for example: the application closed and the last string in the application is xxx2345 then changing the filename to xxx2345.exe

so im looking for rename filename after closing.

Answer 1

There is a difference between after closing and *when (while) * closing the application. I am assuming you want to do the second.

There are few options. One way will be to copy the exe file with a new name.Then 1. Delete the old file via shell command / windows scheduler (say 1 min in future) or 2. when the new file is opened, it deletes the older version (you will need a set formula for file names between version, or a registry / local storage for previous name)

Answer 2

For your question, you want to rename current file name after closing the application.

You could try the following code to get it.

        string str = r.Next(1000).ToString();
        string str1 = Process.GetCurrentProcess().MainModule.ModuleName;     
        Process[] ps = Process.GetProcessesByName(str1);
        if (ps.Length <= 0)
        {
            string filePath = System.Environment.CurrentDirectory; ;            
            string newFileName = filePath + "\\" + str + ".exe";                 
            File.Move(str1, newFileName);
        }

This is my tested result:
