问题描述
我正在编写一个C#类，该类别运行一个流程(REG)来导出注册表键. REG要求您指定要导出的文件名，但我宁愿将REG的输出定向到标准输出，以便我可以直接在C#代码(使用Process.standardOutput)中捕获它. PowerShell是否可以将标准输出指定为文件名?
推荐答案
如果您必须使用REG程序(而不是使用PowerShell查询/转储注册表 - 甚至在C#程序本身中进行此操作)，那么您将要获得的最好的就是允许它要倾倒到临时文件，然后将文件的内容输送回标准，然后在您的C#程序中捕获它:
$guid = [Guid]::NewGuid().ToString("N")
REG EXPORT HKCU\Software\Microsoft\Windows "$env:temp\$guid" | Out-Null
Get-Content "$env:temp\$guid"
Remove-Item "$env:temp\$guid"
如果您不知道:使用PowerShell，则可以浏览注册表，就好像它是文件系统的一部分一样.也许这在其他一些方面有帮助?
cd HKCU:\Software\Microsoft\Windows dir

只需使用'conout $'作为文件名(如在评论中播放的那样，这仅在Windows XP上起作用):
PS C:\> reg export HKLM\SOFTWARE\FileZilla 'CONOUT$' ■W i n d o w s R e g i s t r y E d i t o r V e r s i o n 5 . 0 0 [ H K E Y _ L O C A L _ M A C H I N E \ S O F T W A R E \ F i l e Z i l l a ] " I n s t a l l _ D i r " = " C : \ \ P r o g r a m F i l e s \ \ F i l e Z i l l a " " R u n i n S e c u r e M o d e " = " 0 " " U s e R e g i s t r y " = " 0 " " L a n g u a g e " = " E n g l i s h "
此处显示的输出中有一些Unicode编码问题，但是分析时应该能够在缓冲区中处理.
问题描述
I'm writing a C# class that runs a Process (REG) to export registry keys. REG requires that you specify a filename to export to but I would rather have the output of REG directed to the standard output so I can capture it directly in my C# code (using Process.StandardOutput). Is there a way in PowerShell to specify the standard output as the filename?
推荐答案
If you have to use the REG program (rather than use PowerShell to query/dump the registry - or even just do it in the C# program itself), Probably the best you are going to get is to allow it to dump out to a temporary file, then pipe the contents of the file back to standard out and capture it in your C# program that way:
$guid = [Guid]::NewGuid().ToString("N")
REG EXPORT HKCU\Software\Microsoft\Windows "$env:temp\$guid" | Out-Null
Get-Content "$env:temp\$guid"
Remove-Item "$env:temp\$guid"
In case you were not aware: Using PowerShell, you can navigate the registry as though it were part of the file system. Perhaps this is helpful in some other regard?
cd HKCU:\Software\Microsoft\Windows dir

Just use 'CONOUT$' as the file name (as pojnted out in comments, this only works on Windows XP):
PS C:\> reg export HKLM\SOFTWARE\FileZilla 'CONOUT$' ■W i n d o w s R e g i s t r y E d i t o r V e r s i o n 5 . 0 0 [ H K E Y _ L O C A L _ M A C H I N E \ S O F T W A R E \ F i l e Z i l l a ] " I n s t a l l _ D i r " = " C : \ \ P r o g r a m F i l e s \ \ F i l e Z i l l a " " R u n i n S e c u r e M o d e " = " 0 " " U s e R e g i s t r y " = " 0 " " L a n g u a g e " = " E n g l i s h "
There are some UNICODE encoding issues in the output shown here, but you should be able to handle that in the buffer when you parse it.
