CultureInfo中linux下AllCultures中無zh-CN的問題

CultureInfo類型	含義
NeutralCulture	Neutral cultures are cultures like "en", "de", "zh", etc, for enumeration this includes ALL neutrals regardless of other flags

WindowsOnlyCultures（deprecated）	this will always return empty list
FrameworkCultures（deprecated）	will return only the v2 cultures marked as Framework culture.
InvariantCulture	culture-independent (invariant).it is associated with the English language but not with any country/region

 

當咱們看到 en-US，es-ES等表示culture的名稱時，能夠這樣進行識別
橫線前面的部分稱爲Neutral Culture，它是「與某種語言關聯但不與國家/地區關聯的區域性」的含義
橫線後面的部分稱爲Specific Culture ,它就是和某個地區國家有關的了

只有一種特殊狀況，就是中文,它的關係是這樣的
zh-CHS Chinese (Simplified) , Neutral
zh-CN Chinese - China

zh-CHT Chinese (Traditional) , Neutral
zh-TW Chinese - Taiwan
zh-HK Chinese - Hong Kong SAR
zh-MO Chinese - Macao SAR
zh-SG Chinese - Singapore

 

zh-Hans is not a region name

language-script-region-variant-extension-privateuse

1. language：這部分就是ISO 639規定的代碼，好比中文是zh。

2. script：表示變體，好比簡體漢字是zh-Hans，繁體漢字是zh-Hant。

3. region：表示語言使用的地理區域，好比zh-Hans-CN就是中國大陸使用的簡體中文。

4. variant：表示方言。

5. extension-privateus：表示擴展用途和私有標識。

通常約定，language標籤所有小寫，region標籤所有大寫，script標籤只有首字母大寫。不一樣標籤之間用連字號-連接。

 

 

The example displays the older zh-CHS and zh-CHT culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the zh-Hans name instead of zh-CHS and the zh-Hant name instead of zh-CHT. The zh-Hans and zh-Hant names represent the current standard, and should be used unless you have a reason for using the older names.

Parent :

On Windows, that parent chain for zh-CN is 'zh-CN'->'zh-Hans'->'zh'->Invariant. On Linux, the zh-Hans element is omitted

 

官方聲明：https://github.com/dotnet/docs/issues/11363

zh-CN and zh-TW are two cultures mainly used on Windows and Linux ICU library just support them as aliased cultures. aliased means these cultures are not get enumerated in the cultures list but only work if you create the culture with that aliased name.The right names for such cultures are zh-Hans-CN and zh-Hant-TW.When creating the zh-CN or zh-TW cultures, the parent culture on Linux will be zh and not zh-Hans nor zh-Hant. If running on Windows, will get a different behavior.If create the culture zh-Hans-CN, its parent chain will be zh-Hans -> zhIf create the culture zh-Hant-TW, its parent chain will be zh-Hant -> zh
