C＃Directory.GetDirectories排除文件夹 [英] c# Directory.GetDirectories excluding folders

问题描述

我试图通过Windows用户文件夹列表迭代在C：\Users，但不包括微软内置的用户文件夹，下面是我使用完成这一壮举的代码段，但。这是因为某些原因不能如预期运行

I'm trying to iterate through a list of users folders in windows in "c:\Users" but exclude the microsoft built-in user folders, the below is the code segment I'm using to accomplish this feat but it's for some reason not working as intended.

private readonly List<String> _exclusion = new List<String>
                                                   {
                                                       "All Users",
                                                       "Default",
                                                       "LocalService",
                                                       "Public",
                                                       "Administrator",
                                                       "Default User",
                                                       "NetworkService"
                                                   };

public static bool FoundInArray(List<string> arr, string target)
{
    return arr.Exists(p => p.Trim() == target);
}

foreach (string d in Directory.GetDirectories(sDir).Where(d => !FoundInArray(_exclusion,d)))
{
    richTextBox1.Text += d + Environment.Newline;
}

我不知道为什么，这是行不通的，任何人都可以提供一些？在这种洞察力我

I'm not sure why this isn't working, can anyone provide some insight on this for me?

推荐答案

在您的lambda表达式：D是目录的全名（与路径），因此，实际上不是数组中。

In your lambda expression: 'd' is the full name of the directory (with the path), and therefore is not actually in the array.

您可以这样做：

public static bool FoundInArray(List<string> arr, string target)
{
    return arr.Any(p => new DirectoryInfo(target).Name == p);
}
