在c＃winform中搜索文件

问题描述：

我正在尝试列出C的所有目录和文件：

I am trying to list all Directory and file of C:

I tryed with
Directory.GetDirectories(dir,"*",SearchOption.AllDirectories)

但它抛出错误

but it throwing error

System.UnauthorizedAccessException was unhandled
  Message=Access to the path 'c:\Config.Msi\' is denied.

i希望我的程序继续搜索，但需要验证的文件除外。

i want my program such that it continue its search except that files which required Authentication.

答

为避免这种情况，请不要使用 SearchOption.AllDirectories ，而是自己编写所有递归代码：

To avoid this, don't use SearchOption.AllDirectories, but write all the recursion code yourself:
