在本地计算机和服务器上都进行了一致Culture
设置,但它们生成了格式不同的DateTime
字符串:
local: "22/11/2016 12:00:00 AM"
server: "22/11/2016 12:00:00 a.m."
我正在编写一个单元测试,无论测试运行在哪里,我都希望表现完全相同。为此,我创建了一个自定义属性,以便在测试期间手动设置机器的当前CultureInfo
。这样,如果我在新西兰本地运行测试,它在美国的AWS服务器上运行时仍然会表现相同(在这种情况下,为了确保日期字符串的一致格式,新西兰= dd / mm / yyyy 和美国= mm / dd / yyyy )或世界上任何其他地方。
到目前为止,自定义属性正确设置了机器的文化设置,并正确格式化了新西兰( dd / mm / yyyy )和美国之间的日期和时间( mm / dd / yyyy ),除了我的本地机器输出“AM”后,服务器输出“am” (参见下面的代码,这是AMDesignator
类的DateTimeFormat
属性)。似乎服务器正在从指定的CultureInfo
之外获取格式设置,为什么会发生这种情况?我错过了什么吗?
注意 - CultureSwitcher.SetTo(CultureInfo culture)
将CurrentCulture
和CurrentUICulture
设置为所提供的指定CultureInfo
。
using (var poly = PAssert.Poly())

var date = new DateTime(2016, 11, 22);
// New Zealand culture
using (CultureSwitcher.SetTo(new CultureInfo("en-NZ")))
{
var currentCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
var amDesignator = currentCulture.DateTimeFormat.AMDesignator;
var currencySymbol = currentCulture.NumberFormat.CurrencySymbol;
