如何删除超过7天C＃/ NET的文件夹

Question

I want to write some code that deletes all DIRECTORIES older than 7 days.

So:

1. Check directory : D:\\this
2. If folder older than 7 days -> delete it from the system.

Answer 1

You can lookup using the DirectoryInfo util

   DirectoryInfo d = new DirectoryInfo(dir);
   if (d.CreationTime    < DateTime.Now.AddDays(-7))
       d.Delete();

Answer 2

You can use DirectoryInfo

The voice of experience says to include sanity checks in your code that the directories you are deleting are in fact ones that you want to be deleting...
