去除文件只读属性、判断文件夹及文件的隐藏属性

  if (System.IO.File.GetAttributes(filePath).ToString().IndexOf("ReadOnly") != -1)//去除文件只读属性
   {
     File.SetAttributes(filePath, FileAttributes.Normal);
   }

string[] folders = Directory.GetDirectories(path);
foreach (string fo in folders)
{
DirectoryInfo di = new DirectoryInfo(fo); 
 if ((di.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)//文件夹不是隐藏的
 {
  ......
 }
}

 string[] files = Directory.GetFiles(path);
 foreach (string f in files)
{  
  FileInfo fi = new FileInfo(f);
  if ((fi.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)
  {
  }
}
