在桌面新建一个文件file-to-delete.txt，设置只读属性。先删除，然后从回收站还原
[Test] public void FileAttributeTest() { var desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop); var fileName = "file-to-delete.txt"; var path = Path.Combine(desktop, fileName); var attributes = File.GetAttributes(path); Console.WriteLine(attributes); }
输出结果为 ReadOnly, Archive
static void Main(string[] args) { try { var desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop); var fileName = "file-to-delete.txt"; var path = Path.Combine(desktop, fileName); Console.WriteLine(); if (File.Exists(path)) { Console.WriteLine(File.GetAttributes(path)); File.Delete(path); } } catch (Exception ex) { Console.WriteLine(ex); } finally { Console.ReadLine(); } }
ReadOnly
