Question

Windows 10支持自定义区域设置，这些区域设置没有LCID，例如旧版Windows中的旧版本区域设置。在Windows 10的每次更新中，Microsoft一直在为少数民族和土着语言添加较少使用的语言环境。

Windows 10的最新更新添加了Võrokii（vro）语言环境。使用EnumSystemLocalesEx枚举所有支持的区域设置时，vro不会以任何形式显示。但是，在用于添加新语言或键盘的系统设置UI中，确实会出现Võrokiil。

但是，如果用户随后启用了此语言，则当您拨打EnumSystemLocalesEx时，vro，vro-Latn和vro-Latn-001现已列出。如果用户随后从UI中删除了此区域设置，则它不再出现在此函数调用的结果中。

问题：是否有办法（支持或以其他方式）获取操作系统中所有已知语言环境的列表，无论用户是否已启用它们？

我发现这个输出包括Skolt Sami等其他少数民族语言而不要求用户提前启用它，这一点非常奇怪。

如果在C / C ++ API中不存在API，我将非常高兴地接受使用.NET框架的答案，只要我能够真正获得此数据。

生成语言环境输出的示例代码：

#include <cstdio>
#include "stdafx.h"
#include "windows.h"

BOOL CALLBACK Callback(LPWSTR pStr, DWORD dwFlags, LPARAM lparam)
{
    wprintf(L"%ls\n", pStr);
    return TRUE;
}

int main()
{
    EnumSystemLocalesEx(Callback, 0, 0, 0);
    return 0;
}

通过系统设置中的“地区和语言”屏幕启用Võrokii，最后三个结果为vro-Latn，vro-Latn-001和vro。未启用时，它们根本不会出现在输出中。

使用.NET API似乎具有相同的行为。

#include "stdafx.h"

using namespace System;
using namespace System::Globalization;
int main()
{
    System::Collections::IEnumerator^ enum0 = CultureInfo::GetCultures(CultureTypes::AllCultures)->GetEnumerator();
    while (enum0->MoveNext())
    {
        CultureInfo^ ci = safe_cast<CultureInfo^>(enum0->Current);
        Console::WriteLine("{0}", ci->Name);
    }
}

实际上，用于Windows的新语言模型意味着除了具有历史LCID的语言列表之外，没有“列表”。

Windows 8.1和10设置工具链接到bcp47langs.dll和winlangdb.dll，只要提供的输入是有效的ISO 639-3语言代码，它们就会提供用于启用语言和输入法的功能。 / p>

在某些情况下，如果希望您的语言出现在UI中或通过这些API出现，则必须至少提供脚本，有时甚至还提供区域。一个示例是myv-Cyrl的Erzya语言。

使用这些API

在与PowerShell捆绑在一起的cmdlet上使用MSIL反汇编程序，我发现了p / invoke定义，它使我能够成功地使用C＃和Rust代码中的这些API。
