Příklady

Následující příklad ukazuje, jak načíst NumberFormatInfo objekt pro odpovídající CultureInfo objekt a použít načtený objekt k dotazování na informace o formátování čísel pro konkrétní jazykovou verzi.

using namespace System;
using namespace System::Globalization;
using namespace System::Text;

int main()
{
    StringBuilder^ builder = gcnew StringBuilder();

    // Loop through all the specific cultures known to the CLR.
    for each(CultureInfo^ culture in 
        CultureInfo::GetCultures (CultureTypes::SpecificCultures)) 
    {
        // Only show the currency symbols for cultures 
        // that speak English.
        if (culture->TwoLetterISOLanguageName == "en")
        {
            // Display the culture name and currency symbol.
