在C＃中仅列出子文件夹？

Question

我有一些代码：

string pathUser = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);
string pathDownload = Path.Combine(pathUser, @"documents\iracing\setups\");
DirectoryInfo dinfo = new DirectoryInfo(pathDownload); // Populates field with all Sub Folders
FileInfo[] Files = dinfo.GetFiles("*.sto");
foreach (FileInfo file in Files)
{
     listBox2.Items.Add(file.Name);
}

我希望显示：documents\iracing\setups\的子文件夹，而不是文件...包括.sto文件。我只需要列出子文件夹....我不知道该怎么做？谢谢！

Answer 1

你可以试试这个：

DirectoryInfo directory = new DirectoryInfo(pathDownload);
DirectoryInfo[] directories = directory.GetDirectories();

foreach(DirectoryInfo folder in directories)
     listBox2.Items.Add(folder.Name);

Answer 2

只需使用此功能

string pathUser = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);
string pathDownload = Path.Combine(pathUser, @"documents\iracing\setups\");
DirectoryInfo dinfo = new DirectoryInfo(pathUser); // Populates field with all Sub Folders
DirectoryInfo[] directorys = dinfo.GetDirectories();
foreach (DirectoryInfo directory in directorys)
{
    listBox2.Items.Add(directory.Name);
}

如果您希望获取...目录，请使用EnumerateDirectories或GetDirectories代替GetFiles。
