PowerShell的更改范围符合多个命令-UICulture [英] PowerShell scope of changes in lines with multiple commands - UICulture

问题描述

在修改PS 5.1期间，与问题目标有关完全更改当前PowerShell会话的语言 我观察到奇怪"的情况.行为:

During my tinkering with PS 5.1 related to the objective of question Fully change language for the current PowerShell session I observed a "strange" behavior:

> [system.threading.thread]::currentthread.currentculture ; [system.threading.thread]::currentthread.currentuiculture ;
LCID             Name             DisplayName
----             ----             -----------
1033             en-US            English (United States)
1033             en-US            English (United States)
> function Set-CultureWin([System.Globalization.CultureInfo] $culture) { [System.Threading.Thread]::CurrentThread.CurrentUICulture = $culture ; [System.Threading.Thread]::CurrentThread.CurrentCulture = $culture } ; Set-CultureWin es-ES ; [system.threading.thread]::currentthread.currentculture ; [system.threading.thread]::currentthread.currentuiculture ;
LCID             Name             DisplayName
----             ----             -----------
3082             es-ES            Español (España)
3082             es-ES            Español (España)
> [system.threading.thread]::currentthread.currentculture ; [system.threading.thread]::currentthread.currentuiculture ;
LCID             Name             DisplayName
----             ----             -----------
1033             en-US            English (United States)
1033             en-US            English (United States)

(上面的功能是从此处获得的). 到处都用[cultureinfo]::替换[system.threading.thread]::currentthread.会产生完全相同的结果.

(the function above was obtained from here). Replacing [system.threading.thread]::currentthread. with [cultureinfo]:: everywhere produced exactly the same results.

我发现奇怪的是:

我得出的结论是，线程"的边界是不规则的. (当前线程)似乎是执行命令行.
不过，在此处，它被引用为会话范围的(非持久性)解决方案". (针对其OP >暂时将powershell语言更改为英语?). 该答案甚至发布了一个包装函数，以将更改范围限制为正在执行的命令.
该信息显然反对此，其中指出"[Threading.Thread]::CurrentThread.CurrentUICulture仅影响当前的单线". (与我的结论一致).

1. I conclude that the boundary of a "thread" (the currentthread) appears to be the execution command line.
   Nevertheless, here it is quoted as "a session-scoped (non-persistent) solution" (in response to its OP Temporarily change powershell language to English?). That answer even posted a wrapper function to limit the scope of the change to the executing command.
   This information apparently opposes this, which states "[Threading.Thread]::CurrentThread.CurrentUICulture only affects to current one-liner" (coinciding with my conclusion).

即使Set-Culture仅在启动新会话后才生效，我也可以仅针对一个线程"立即获得Culture的更改.
我可能会得出结论，那就是它的工作原理.

I can obtain an immediate change of Culture for just that one "thread", even if Set-Culture only takes effect after launching a new session.
I might conclude that's how it works.

如何合理化这两点? (我欢迎权威文档.)

How can these two points be rationalized? (I would welcome authoritative documentation).

推荐答案

由于 Windows PowerShell 中的 bug (PowerShell [Core] v6 +不受 的影响)，在会话期间对[cultureinfo]::CurrentUICulture和[cultureinfo]::CurrentCulture所做的更改将在启动时自动重置为值 每当命令完成执行时，在命令提示符下>> ^[1] .

Due to a bug in Windows PowerShell (PowerShell [Core] v6+ is not affected), in-session changes to [cultureinfo]::CurrentUICulture and [cultureinfo]::CurrentCulture are automatically reset to the values at startup time^[1] at the command prompt, whenever a command finishes executing.

不幸的是，尝试修改$PROFILE中的区域性也会受到同样的影响.

Trying to modify the culture(s) in $PROFILE is equally affected, unfortunately.

但是，对于给定的脚本，脚本内区域性更改对于整个脚本及其被调用方(在主线程上)仍然有效-请参见

However, for a given script, in-script culture changes remain in effect for the entire script as well as its callees (on the main thread) - see this answer.

唯一的解决方法是在启动PowerShell之前更改当前用户的操作系统级别语言/区域设置

The only workaround is to change the current user's OS-level language / locale settings before starting PowerShell.

以编程方式

• ，您可以使用显示语言( UI文化，反映在[cultureinfo]::CurrentUICulture中). microsoft.com/en-us/powershell/module/international/set-winuilanguageoverride"rel =" nofollow noreferrer> Set-WinUILanguageOverride

• you can change the current user's display language (UI culture, reflected in [cultureinfo]::CurrentUICulture) with Set-WinUILanguageOverride

您可以使用

you can change the locale (culture, reflected in [cultureinfo]::CurrentCulture) with Set-Culture

请注意，这两个命令都至少需要Windows 8/Windows Server 2012，并且仅在未来会话中生效.

Note that both commands require at least Windows 8 / Windows Server 2012 and only take effect in future sessions.

^{[1] PowerShell 进程启动时的值，由用户的操作系统级别的语言和区域设置确定.}

^{[1] The values at startup of the PowerShell process, as determined by the user's OS-level language and locale settings.}
