Question

好的，这是我目前的问题：

这是我的主要内容：

//System prompts user the type of archiving which will direct to the correct directory to set as root
Console.WriteLine("Enter the type of archiving you would like to do?");
string archivetype = Console.ReadLine(); 

//function that identifies which candidates to archive
Archive(archivetype, 20, 20);

//keep the application in debug mode
Console.ReadKey();

存档方法：

//Archive method determines which directory to search in and how many versions to archive
static void Archive(string archivetype, int pversion, int version)
{
    //regex pattern to get folder names of the type #.#.#.#/#. something
    Regex reg = new Regex(@"\d+(\.\d+)+");
    //setting where to start looking
    DirectoryInfo root = new           DirectoryInfo(@"C:\Users\jphillips\Desktop\test\parent\ACE-3_0");
    var dirs = new List<DirectoryInfo>();
    //i want to make a recursive call to all the folders in my root directory to obtain all the folders with the regex pattern above that are not empty and do not have 3 files inside
    WalkDirectoryTree(root);      
}

最后走了directorytree方法

//so im using the walk directory tree on the microsoft website i need a way to have a sort of a global array to keep adding the directories that fit through the patterns mentioned above without resetting itself after each walkdirectorytree call
static void WalkDirectoryTree(System.IO.DirectoryInfo root)
{
    DirectoryInfo[] subDirs = null;

    // Now find all the subdirectories under this root directory.
    subDirs = root.GetDirectories();

    foreach (DirectoryInfo dir in subDirs)
    {
        //dirs is not global so it doesnt work here and i believe if i put a local array that it will reset itself everytime
        dirs = root.GetDirectories("*", SearchOption.TopDirectoryOnly).Where(d => reg.IsMatch(d.Name)).ToList();
        if()
        WalkDirectoryTree(dir);
    }
}

所以我真的失去了这一点我想能够调用walkdirectorytree来遍历我的目录的所有文件夹和子文件夹recursevely来扩展具有正则表达式模式的路径并且不是空的并且里面没有3个文件tp给我一个这些文件夹路径的列表。

Answer 1

您可以通过GetDirectories的重载在一次通话中获取所有文件夹和子文件夹。

你传入一个搜索字符串 - 但不幸的是不是正则表达式而是SearchOption.AllDirectories作为第二个参数。然后，您可以通过正则表达式传递结果，以找到您感兴趣的结果。

获取目录下的子文件夹列表
