使用 .NET 删除目录中超过 3 个月的文件 [英] Delete files older than 3 months old in a directory using .NET

问题描述

我想知道(使用 C#)如何删除某个目录中超过 3 个月的文件，但我想日期期限可能是灵活的.

I would like to know (using C#) how I can delete files in a certain directory older than 3 months, but I guess the date period could be flexible.

需要说明的是:我正在查找 90 天之前的文件，换句话说，应保留少于 90 天前创建的文件，删除所有其他文件.

Just to be clear: I am looking for files that are older than 90 days, in other words files created less than 90 days ago should be kept, all others deleted.

推荐答案

像这样的事情不要去做.

Something like this outta do it.

using System.IO; 

string[] files = Directory.GetFiles(dirName);

foreach (string file in files)
{
   FileInfo fi = new FileInfo(file);
   if (fi.LastAccessTime < DateTime.Now.AddMonths(-3))
      fi.Delete();
}
