如何过滤c＃中的不可见文件？

Question

我想在C＃中查找文件夹中的所有不可见文件。我可以枚举文件

var files = from file in 
   Directory.EnumerateFiles(@"c:\", "*.txt", SearchOption.AllDirectories)
select new
{
File = file
};

Answer 1

您可以使用FileInfo类检查文件属性：

            FileInfo f = new FileInfo(path);
            if ((f.Attributes & FileAttributes.Hidden) != 0)

Answer 2

来自previous SO post

DirectoryInfo directory = new DirectoryInfo(@"C:\");
FileInfo[] files = directory.GetFiles();

var filtered = files.Where(f => f.Attributes.HasFlag(FileAttributes.Hidden));

foreach (var f in filtered)
{
    Debug.WriteLine(f);
}
