C#删除只读文件或文件夹(解决File.Delete无法删除文件)

 if (File.GetAttributes(FFName).ToString().IndexOf("ReadOnly") != -1) File.SetAttributes(FFName, FileAttributes.Normal); File.Delete(FFName);//不能删除只读文件

/// <summary>    ///  用来遍历删除目录下的文件以及该文件夹    /// </summary>    public void DeleteFileByDirectory(DirectoryInfo info)    {      foreach (DirectoryInfo newInfo in info.GetDirectories())      {        DeleteFileByDirectory(newInfo);      }      foreach (FileInfo newInfo in info.GetFiles())      {        newInfo.Attributes = newInfo.Attributes &~(FileAttributes.Archive | FileAttributes.ReadOnly | FileAttributes.Hidden);        newInfo.Delete();      }      info.Attributes = info.Attributes & ~(FileAttributes.Archive | FileAttributes.ReadOnly | FileAttributes.Hidden);      info.Delete();    }
