该系统找不到指定的路径 [英] The system cannot find the path specified

问题描述

我正在尝试使用 C# 计算位置 %system%\drivers\ 中某些文件的 sha1 哈希值.我知道文件在确切的位置，但是当我使用

I am trying to calculate sha1 hash for some of the files from location %system%\drivers\ using C#. I know files are at the exact location but when i use

FILE.Exists("c:\\Windows\\System32\\Drivers\\1394ohci.sys") 

它总是返回 false.

it always retuns false.

C:\Users\administrator>dir c:\Windows\System32\drivers\1394ohci.sys
 Volume in drive C has no label.
 Volume Serial Number is 5A4F-1E60

 Directory of c:\Windows\System32\drivers

               0 Dir(s)  19,521,245,184 bytes free


C:\Users\administrator>fciv -sha1 c:\Windows\system32\drivers\1394ohci.sys

//
c:\windows\system32\drivers\1394ohci.sys\*
        Error msg  : The system cannot find the path specified.
        Error code : 3

我什至在文件上尝试了 fciv.exe，它也生成了相同的输出.我尝试以管理员身份运行该命令，但没有帮助.

I even tried fciv.exe on the file and it also generate the same output. I tried running the command as administratror but it did not help.

我进行了大量网络搜索，但没有任何效果.请帮助并告诉我如何解决此问题.

I did lot of web search but nothing worked. Please help and let me know how to fix this issue.

感谢您的帮助.谢谢，

推荐答案

如果我正确理解您的问题，那么您需要查看 文件系统重定向器

If I understand your problem correctly then you need to look at File System Redirector

%windir%\System32 目录是 reserved 用于 64 位应用程序.大多数 DLL 文件名在 64 位版本的 DLL 时未更改已创建，因此 32 位版本的 DLL 存储在不同的目录.WOW64 使用文件隐藏了这种差异系统重定向器.

The %windir%\System32 directory is reserved for 64-bit applications. Most DLL file names were not changed when 64-bit versions of the DLLs were created, so 32-bit versions of the DLLs are stored in a different directory. WOW64 hides this difference using a file system redirector.

在大多数情况下，每当 32 位应用程序尝试访问%windir%\System32，访问被重定向到 %windir%\SysWOW64.对 %windir%\lastgood\system32 的访问被重定向到%windir%\lastgood\SysWOW64.对 %windir%\regedit.exe 的访问是重定向到 %windir%\SysWOW64\regedit.exe.

In most cases, whenever a 32-bit application attempts to access %windir%\System32, the access is redirected to %windir%\SysWOW64. Access to %windir%\lastgood\system32 is redirected to %windir%\lastgood\SysWOW64. Access to %windir%\regedit.exe is redirected to %windir%\SysWOW64\regedit.exe.

如果你可以尝试一下，页面底部还有一个小样本

Also there is small sample at the bottom of page if you can try that one

string system32Directory = Path.Combine(Environment.ExpandEnvironmentVariables("%windir%"), "system32");
if(Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
{
// For 32-bit processes on 64-bit systems, %windir%\system32 folder
// can only be accessed by specifying %windir%\sysnative folder.
system32Directory = Path.Combine(Environment.ExpandEnvironmentVariables("%windir%"), "sysnative");
}
