C＃中删除所有空的子目录 [英] C# Remove all empty subdirectories

问题描述

我有一项任务，清理了大量的目录。我想开始在目录，并删除任何子目录（不管有多深）不包含任何文件（文件将永远不会被删除，只有目录）。如果它不包含任何文件或子目录的起始目录将被删除。我希望有人能指出我的一些这方面的现有的代码，而不必另起炉灶。我会做这个使用C＃。

I have a task to clean up a large number of directories. I want to start at a directory and delete any sub-directories (no matter how deep) that contain no files (files will never be deleted, only directories). The starting directory will then be deleted if it contains no files or subdirectories. I was hoping someone could point me to some existing code for this rather than having to reinvent the wheel. I will be doing this using C#.

推荐答案

使用C＃代码。

static void Main(string[] args)
{
    processDirectory(@"c:\temp");
}

private static void processDirectory(string startLocation)
{
    foreach (var directory in Directory.GetDirectories(startLocation))
    {
        processDirectory(directory);
        if (Directory.GetFiles(directory).Length == 0 && 
            Directory.GetDirectories(directory).Length == 0)
        {
            Directory.Delete(directory, false);
        }
    }
}
