如何在VS2017中的不同区域设置中进行调试

Question

I have a nasty bug which manifests itself only when I run my C# program on a non-english Windows. It is a conversion from double to string (I get commas instead of dots on some values we shouldn't localize). In order to test the fix (ie applying InvariantLocale everywhere) I need to build the executable and run it on a non-english VM, it's very time consuming.

My question is: is it possible to debug inside VS2017 pretending to be on a non-english Windows environment? (let's say for example a Dutch Windows)

Answer 1

I use a utility class for setting the language:

public static class LanguageSetter
{
    [DllImport("Kernel32.dll", CharSet = CharSet.Auto)]
    private static extern ushort SetThreadUILanguage(ushort _languageId);

    public static void SetLanguage(string uiLanguage)
    {
        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(uiLanguage);
        SetThreadUILanguage((ushort) Thread.CurrentThread.CurrentUICulture.LCID);
        CultureInfo.DefaultThreadCurrentUICulture = CultureInfo.GetCultureInfo(uiLanguage);
    }
}

Just call it with LanguageSetter.SetLanguage("nl-NL");

If you use WPF, add another line at the end of that function: FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement), new FrameworkPropertyMetadata(XmlLanguage.GetLanguage(CultureInfo.CurrentUICulture.IetfLanguageTag)));
