日期时间格式在ISE和Windows窗体中的显示方式有所不同 [英] Date Time format displays differently in ISE and Windows Forms
问题描述
当我在ISE中运行Get-Date时，会得到所需的Wednesday, 15 April 2020 12:38:03 PM.
When I run Get-Date in ISE, I get Wednesday, 15 April 2020 12:38:03 PM which I want.
但是，如果我在Windows窗体中运行相同的命令，则会以不同的格式得到04/15/2020 12:38:03.
However, if I run the same command in Windows Forms, I get 04/15/2020 12:38:03 in a different format.
我从同一台计算机上运行它们，因此它必须是同一文化/地区.
I run them from the same computer so it must be the same cultural/region.
推荐答案
1.使用-Format或-UFormat
自定义日期
您可以使用-Format或-UFormat参数来强制设置日期的特定布局:
1. Customizing your date using -Format or -UFormat
You can use the -Format or the -UFormat paramater to enforce a certain layout of your date:
Get-Date -Format "dddd, d MMMM yyyy hh:mm:ss tt"
Get-Date -UFormat "%A, %e %B %Y %r"
只要您使用的是en-US区域性信息，两者都将显示所需的日期格式:
Both will display your desired date format, as long as you are using en-US culture information:
Wednesday, 15 April 2020 08:09:24 AM
详细了解:
- .NET format specifiers
- UFormat specifiers
如果要以其他语言显示日期，则还可以强制执行某些区域性信息.请记住，-Format参数只是ToString()方法的包装.因此，您还可以使用以下行根据需要显示日期:
If you want to display the date in a different language, you can also enforce a certain culture information. Keep in mind that the -Format parameter is just a wrapper for the ToString() method. So you can also use the following line to display your date as desired:
(Get-Date).ToString('dddd, d MMMM yyyy hh:mm:ss tt')
幸运的是，该ToString()方法存在不同的重载.还有一个将文化信息作为第二个参数.因此，总而言之，您可以将不同的区域性信息传递给您的ToString()方法，以使用不同的语言获得结果:
Fortunately, there exist different overloads of that ToString() method. There is also one, that takes culture information as a second parameter. So in conclusion you can pass different culture info to your ToString() method to get results in different languages:
$culture = [System.Globalization.CultureInfo]::CreateSpecificCulture('en-US')
(Get-Date).ToString('dddd, d MMMM yyyy hh:mm:ss tt', $culture)
将显示:
Wednesday, 15 April 2020 08:09:24 AM
同时
$culture = [System.Globalization.CultureInfo]::CreateSpecificCulture('de-DE')
(Get-Date).ToString('dddd, d MMMM yyyy hh:mm:ss tt', $culture)
将显示:
Mittwoch, 15 April 2020 08:09:24
3.使用预定义的区域性特定模式自定义日期
在$culture.DateTimeFormat中，您还可以找到已经准备好的文化特定模式来格式化日期，并且可以使用它们而不是自己编写:
3. Customizing your date with predefined culture specific patterns
In $culture.DateTimeFormat you can also find already prepared culture specific patterns to format your date and you can use them instead of writing them on your own:
$culture = [System.Globalization.CultureInfo]::CreateSpecificCulture('en-US')
(Get-Date).ToString($culture.DateTimeFormat.ShortDatePattern, $culture)
将显示:
4/15/2020
同时
$culture = [System.Globalization.CultureInfo]::CreateSpecificCulture('de-DE')
(Get-Date).ToString($culture.DateTimeFormat.ShortDatePattern, $culture)
将显示:
15.04.2020
顺便说一句:在您的问题中指定的与您相似的模式是:
Btw: A similar pattern to yours, specified in your question, would be:
$culture = [System.Globalization.CultureInfo]::CreateSpecificCulture('en-US')
(Get-Date).ToString($culture.DateTimeFormat.FullDateTimePattern, $culture)
