示例

// This scenario uses the Windows.Globalization.NumberFormatting.PercentFormatter and
// the Windows.Globalization.NumberFormatting.PermilleFormatter classes to format numbers
// as a percent or a permille.

//using System.Text;
//using Windows.Globalization.NumberFormatting;

StringBuilder sb = new StringBuilder();

// Create numbers to format.
double randomNumber = new Random().NextDouble();
ulong fixedNumber = 500;

// Create percent formatters.
PercentFormatter defaultPercentFormatter = new PercentFormatter();
PercentFormatter languagePercentFormatter = new PercentFormatter(new[] { "fr-FR" }, "ZZ");

// Create permille formatters.
PermilleFormatter defaultPermilleFormatter = new PermilleFormatter();
PermilleFormatter languagePermilleFormatter = new PermilleFormatter(new[] { "ar" }, "ZZ");

// Format random numbers as percent or permille.
sb.AppendLine("Random number: " + randomNumber);
sb.AppendLine("Percent formatted: " + defaultPercentFormatter.Format(randomNumber));
sb.AppendLine("Permille formatted: " + defaultPermilleFormatter.Format(randomNumber));
sb.AppendLine();
sb.AppendLine("Language-specific percent formatted: " + languagePercentFormatter.Format(randomNumber));
sb.AppendLine("Language-specific permille formatted: " + languagePermilleFormatter.Format(randomNumber));
sb.AppendLine();
sb.AppendLine("Fixed number: " + fixedNumber);

// Format fixed number with grouping.
defaultPercentFormatter.IsGrouped = true;
sb.AppendLine("Percent formatted (grouped): " + defaultPercentFormatter.Format(fixedNumber));

//Format with grouping using French language.
languagePercentFormatter.IsGrouped = true;
sb.AppendLine("Percent formatted (grouped as fr-FR): " + defaultPercentFormatter.Format(fixedNumber));

// Format with no fraction digits.
defaultPercentFormatter.FractionDigits = 0;
sb.AppendLine("Percent formatted (no fractional digits): " + defaultPercentFormatter.Format(fixedNumber));

// Format always with a decimal point.
defaultPercentFormatter.IsDecimalPointAlwaysDisplayed = true;
sb.AppendLine("Percent formatted (always with a decimal point): " + defaultPercentFormatter.Format(fixedNumber));

注解

注意

如果你的应用将此类中使用的语言标记传递给任何 国家/地区语言支持 函数,则它必须首先通过调用 ResolveLocaleName 来转换标记。
