C#UnauthorizedAccessException到用户文件夹 [英] C# UnauthorizedAccessException to User Folder
问题描述
我试图列出用户文件夹"Thomas"中的所有文件夹和文件，然后我想获取这些文件夹中的所有文件夹以及文件等.但是，每当我运行它时，它都会引发此异常:
I'm trying to list all folders and files in my User folder which is "Thomas", then I want to get all of the folders in those folders as well as files and so on. But whenever I run it, it throws this exception:
System.UnauthorizedAccessException: Access to the path 'C:\Users\Thomas\AppData\Local\Application Data' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileSystemEnumerableIterator`1.AddSearchableDirsToStack(SearchData localSearchData)
at System.IO.FileSystemEnumerableIterator`1.MoveNext()
at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
at System.IO.Directory.GetDirectories(String path, String searchPattern, SearchOption searchOption)
at GetFilesInFolders.Program.Main(String[] args) in c:\users\thomas\documents\visual studio 2017\Projects\GetFilesInFolders\GetFilesInFolders\Program.cs:line 23
由于我拥有访问此文件夹的完全许可权，因此我发现这很奇怪，但是出于某种原因，它却另有说明.
I find this strange since I have FULL permission to access this folder, but for some reason it says other-wise.
所有代码都在下面:
using System;
using System.IO;
using System.Collections.Generic;
namespace GetFilesInFolders
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter a path: ");
string path = Console.ReadLine();
int UnauthorizedAccessCount = 0;//counter for file i cant access
List<string> DirList = new List<string>();
List<string> FileList = new List<string>();
try
{
if (Directory.Exists(path))
{
foreach (string dir in Directory.GetDirectories(path, "*", SearchOption.AllDirectories))
{
DirList.Add(dir);
}
foreach (string file in Directory.GetFiles(path, "*", SearchOption.AllDirectories))
{
FileList.Add(file);
}
}
else
{
Console.WriteLine("Directory does not exist!");
Console.ReadKey();
return;
}
}
catch (UnauthorizedAccessException ex)
{
Console.WriteLine("{0}", ex);
}
if(FileList.Count == 0)
{
Console.WriteLine("There were no files, or you didn't have proper permissions. (You didn't have permission to {0} files or folders", UnauthorizedAccessCount);
Console.ReadKey();
}
if(DirList.Count == 0)
{
Console.WriteLine("There were no folders, or you didn't have proper permissions. (You didn't have permission to {0} files or folders", UnauthorizedAccessCount);
Console.ReadLine();
}
else
{
Console.WriteLine("Here are all the folders:\n");
foreach (string dir in DirList)
{
Console.WriteLine(dir);
}
Console.WriteLine("Here are all the files:\n");
foreach (string file in FileList)
{
Console.WriteLine(file);
}
if (UnauthorizedAccessCount != 0)
{
Console.WriteLine("You had no permission to access {0} files.", UnauthorizedAccessCount);
}
else
{
}
Console.ReadLine();
}
}
}
}
推荐答案
您说您拥有完全许可权，但控制台脚本不会以该帐户的特权运行.它以默认用户特权运行，App Data是Windows中的受限文件夹(一般用户不应在其中浏览).
You say you have full permission, but a console script does not run with the priviliges of the account. It runs with default user priviliges, and App Datais a restricted folder in Windows (where normal users are not supposed to poke around).
将控制台应用程序更改为以管理员身份实际运行.有关此操作的信息，请参见以下答案:
Change your console application to actually run as administrator. See this answer on how to do that:
