如何在.NET中将整数转换为本地化字符串?

Exemptigratia:

Int64 value = 12345678901;

value.ToString();  
   // returns "12345678901", should be "123,4567,8901"

value.ToString(CultureInfo.CurrentCulture);  
   // returns "12345678901", should be "123,4567,8901"

value.ToString(CultureInfo.CreateSpecificCulture("en-US")) 
   // returns "12345678901", should be "12,345,678,901"

value.ToString(CultureInfo.CreateSpecificCulture("fr-CH"))
   // returns "12345678901", should be "12'345'678'901"

value.ToString(CultureInfo.CreateSpecificCulture("te-IN"))
   // returns "12345678901", should be "12,34,56,78,901"

如何在.NET中将整数(或浮点数)转换为本地化字符串?

世界上唯一的数字格式列表:

  • 12 345 678 901
  • 12,34,56,78,901
  • 12345678901
  • 12.345.678.901
  • 12?345?678?901
  • 123,4567,8901
  • 12'345'678'901

可在.NET中找到这些文化设置的其他奖励信息:

CultureInfo.CreateSpecificCulture("en-US").NumberFormat.NumberGroupSizes = { 3 }
CultureInfo.CreateSpecificCulture("en-US").NumberFormat.NumberGroupSeparator = ","

CultureInfo.CreateSpecificCulture("te-IN").NumberFormat.NumberGroupSizes = { 3, 2 }
CultureInfo.CreateSpecificCulture("te-IN").NumberFormat.NumberGroupSeparator = ","

CultureInfo.CreateSpecificCulture("te-IN").NumberFormat.NumberGroupSizes = { 3 }
CultureInfo.CreateSpecificCulture("te-IN").NumberFormat.NumberGroupSeparator = "'"

答案 0 :(得分:9)

使用精度为0的“N”standard format specifier

using System;

class Test
{
    static void Main() 
    {
        long value = 12345678901;
        string text = value.ToString("N0");
        Console.WriteLine(text);
    }
}

结果(在我的英国机器上):

12,345,678,901

这将考虑到当前文化的各个方面。当然,您可以单独指定文化。

修改:特定文化的广义形式:

value.ToString("N0", CultureInfo.CreateSpecificCulture("fr-CH"));
