C#枚举目录不应使用本地化路径

Question

下面的代码产生以下输出：

C:ProgramDataMicrosoftWindowsStart MenuPrograms

C:ProgramDataMicrosoftWindowsStart MenuProgramme(德语本地化(

问题：它们都引用了同一个目录，但我不能在本地化路径上调用EnumerateFiles(这无论如何都没有意义(，因为它会生成System.UnauthorizedAccessException，这也意味着我不能将EnumerateFiles与SearchOption.AllDirectories一起使用，因为我得到了相同的Exception。

有没有办法只从EnumerateDirectories中获取功能性非本地化路径？

//Root Directory is C:ProgramDataMicrosoftWindowsStart Menu
foreach(DirectoryInfo directoryInfo in rootDirectory.EnumerateDirectories("*", SearchOption.TopDirectoryOnly))
{
Console.WriteLine("Dir: " + directoryInfo.FullName);
//C:ProgramDataMicrosoftWindowsStart MenuProgramme
//C:ProgramDataMicrosoftWindowsStart MenuPrograms
foreach (FileInfo fileInfo in directoryInfo.EnumerateFiles("*", SearchOption.TopDirectoryOnly))
{
//do stuff
}
}

您必须递归地遍历每个目录，以便在无法访问文件夹时添加异常处理程序。以下是代码的示例

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace SAveDirectoriesXml
{
class Program
{
const string FILENAME = @"c:temptest.xml";
const string FOLDER = @"c:temp";
static XmlWriter writer = null;
static void Main(string[] args)
{
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
writer = XmlWriter.Create(FILENAME, settings);
writer.WriteStartDocument(true);
DirectoryInfo info = new DirectoryInfo(FOLDER);
WriteTree(info);

writer.WriteEndDocument();
writer.Flush();
writer.Close();
Console.WriteLine("Enter Return");
Console.ReadLine();
}
static long WriteTree(DirectoryInfo info)
{
long size = 0;
writer.WriteStartElement("Folder");
try
{
writer.WriteAttributeString("name", info.Name);
writer.WriteAttributeString("numberSubFolders", info.GetDirectories().Count().ToString());
writer.WriteAttributeString("numberFiles", info.GetFiles().Count().ToString());
writer.WriteAttributeString("date", info.LastWriteTime.ToString());

foreach (DirectoryInfo childInfo in info.GetDirectories())
{
size += WriteTree(childInfo);
}

}
catch (Exception ex)
{
string errorMsg = string.Format("Exception Folder : {0}, Error : {1}", info.FullName, ex.Message);
Console.WriteLine(errorMsg);
writer.WriteElementString("Error", errorMsg);
}
FileInfo[] fileInfo = null;
try
{
fileInfo = info.GetFiles();
}
catch (Exception ex)
{
string errorMsg = string.Format("Exception FileInfo : {0}, Error : {1}", info.FullName, ex.Message);
Console.WriteLine(errorMsg);
writer.WriteElementString("Error",errorMsg);
}
if (fileInfo != null)
{
foreach (FileInfo finfo in fileInfo)
{
try
{
writer.WriteStartElement("File");
writer.WriteAttributeString("name", finfo.Name);
writer.WriteAttributeString("size", finfo.Length.ToString());
writer.WriteAttributeString("date", info.LastWriteTime.ToString());
writer.WriteEndElement();
size += finfo.Length;
}
catch (Exception ex)
{
string errorMsg = string.Format("Exception File : {0}, Error : {1}", finfo.FullName, ex.Message);
Console.WriteLine(errorMsg);
writer.WriteElementString("Error", errorMsg);
}
}
}
writer.WriteElementString("size", size.ToString());
writer.WriteEndElement();
return size;
}
}
}
