我正在开发一个项目,我需要列出目录中的所有子目录,例如我如何列出c:\
中的所有子目录答案 0 :(得分:109)
使用Directory.GetDirectories
获取“your_directory_path”指定的目录的子目录。结果是一个字符串数组。
var directories = Directory.GetDirectories("your_directory_path");
默认情况下,只返回一级深度的子目录。可以选择以递归方式返回所有内容并过滤结果documented here,并在Clive的答案中显示。
避免UnauthorizedAccessException
如果你点击了一个你无权访问的目录,很容易得到UnauthorizedAccessException
。
您可能必须创建自己的方法来处理异常,如下所示:
public class CustomSearcher
{
public static List<string> GetDirectories(string path, string searchPattern = "*",
SearchOption searchOption = SearchOption.TopDirectoryOnly)
{
if (searchOption == SearchOption.TopDirectoryOnly)
return Directory.GetDirectories(path, searchPattern).ToList();
var directories = new List<string>(GetDirectories(path, searchPattern));
for (var i = 0; i < directories.Count; i++)
directories.AddRange(GetDirectories(directories[i], searchPattern));
return directories;
}
private static List<string> GetDirectories(string path, string searchPattern)
{
try
{
return Directory.GetDirectories(path, searchPattern).ToList();
}
catch (UnauthorizedAccessException)
{
return new List<string>();
}
}
}
然后像这样称呼它:
var directories = CustomSearcher.GetDirectories("your_directory_path");

FolderBrowserDialog fbd = new FolderBrowserDialog();
DialogResult result = fbd.ShowDialog();
string[] files = Directory.GetFiles(fbd.SelectedPath);
string[] dirs = Directory.GetDirectories(fbd.SelectedPath);
foreach (string item2 in dirs)
{
FileInfo f = new FileInfo(item2);
listBox1.Items.Add(f.Name);
}
foreach (string item in files)
{
FileInfo f = new FileInfo(item);

要获取没有完整路径的简单文件夹列表,可以使用:
Directory.GetDirectories(parentDirectory).Select(d => Path.GetRelativePath(parentDirectory, d)
