添加递归命令以在C#中设置子目录权限
本文关键字:设置 子目录 权限 递归 命令 添加 | 更新日期: 2023-09-27 18:28:47
我想向该脚本添加一个递归命令,使其能够循环通过当前目录子目录/文件,并将子文件夹/文件的权限设置为我想要的任何权限。以下是到目前为止我所拥有的内容,它允许更改第一组子目录的权限。显然,我可以在中添加相同的代码来继续深入文件夹结构,但并不是每个根文件夹中都有相同数量的子文件夹。我想添加递归命令来遍历所有子目录,当没有子目录时,转到下一个根文件夹。

首先,如果您的目标框架是4.0,建议您使用Directory.EnumerateFiles方法(您也可以找到做同样事情的第三个代码。)
假设这是不可行的,你可以通过使用yield关键字来简化递归处理,例如,制作一个基于yield的遍历方法——我用过滤器函数来展示这一点,因为它在目录遍历中通常很有用。广告应该给你一些想法。
static IEnumerable<string> traverse(string path, Func<string, bool> filter)
{
foreach (string f in Directory.GetFiles(path).Where(filter))
{
yield return f;
}
foreach (string d in Directory.GetDirectories(path))
{
foreach (string f in traverse(d, filter))
{
yield return f;
}
}
}
然后你用这种方式遍历()
var files = traverse(PATH, WHERE);
foreach (string f in files) { DoWhatever; }
您将拥有一个更容易重复使用的目录遍历触手可及。我知道我不会在上面的代码段中生成目录,但如果我想同时处理文件和目录,我会基于DirectoryInfo.GetFileSystemInfos方法。
我忘了什么时候添加了yield功能,但它已经使用了很长一段时间。
