如何将字符串格式化为越南货币? [英] How to format a string as Vietnamese currency?

问题描述

如果我将[地区和语言]中的格式设置为美国...

If I set Format in [Region and Language] to US...

CultureInfo cul = CultureInfo.CurrentCulture;
string decimalSep = cul.NumberFormat.CurrencyDecimalSeparator;//decimalSep ='.'
string groupSep = cul.NumberFormat.CurrencyGroupSeparator;//groupSep=','
sFormat = string.Format("#{0}###", groupSep);
string a = double.Parse(12345).ToString(sFormat);

结果是:12,345(正确)

但是，如果我将[区域和语言]中的格式设置为VietNam，则结果为:12345

But if I set the format in [Region and Language] to VietNam, then the result is: 12345

结果应为12.345.

你能帮我吗?谢谢.

推荐答案

您正在提供过多帮助.格式说明符不区分区域性，您始终使用逗号指示分组字符的位置.格式化字符串后，将使用实际的分组字符替换该字符.

You are helping too much. The format specifier is culture insensitive, you always use a comma to indicate where the grouping character goes. Which is then substituted by the actual grouping character when the string is formatted.

此格式正确:

        CultureInfo cul = CultureInfo.GetCultureInfo("vi-VN");   // try with "en-US"
        string a = double.Parse("12345").ToString("#,###", cul.NumberFormat);

您实际上应该使用#，#"来确保它在具有不常见分组的文化中仍然可以使用.从这个问题尚不清楚，这是否很重要，所以我为#，###"打了个招.

You should actually use "#,#" to ensure it still works in cultures that have a uncommon grouping. It wasn't clear from the question whether that mattered or not so I punted for "#,###"
