Question

.net中有很多格式说明符，例如C表示货币，D表示小数。许多定义的格式可以是here。

如何根据给定的区域设置获得格式说明符后面的确切格式。

E.g。（我在这里假设en-US语言环境）

GetFormatSpecifierText（＆＃34; C＆＃34;）应该返回＆＃34; $＆＃34; ＃，## 0.00

GetFormatSpecifierText（＆＃34; F＆＃34;）应该返回＆＃34;＃，## 0.00

Answer 1

了解Culture如何与格式说明符结合使用。我相信您可能正在寻找以下code from MSDN:

中的覆盖

public class userOverrideSample
{
   [WebMethod]
   public String UserLocalSetting()
   {
      int i = 100;

      // Sets the CurrentCulture to French in France.
      Thread.CurrentThread.CurrentCulture = new CultureInfo("fr-FR");
      // Displays i formatted as currency for the CurrentCulture.
      // Due to operating system differences, you cannot be sure what currency
      // symbol will be used.
      return (i.ToString("c"));
   }   

   [WebMethod]
   public String OverrideUserSetting()
   {
      int i = 100;

      // Sets the CurrentCulture to French in France.
      // Uses the CultureInfo constructor that takes a 
      // useUserOverride parameter.
      // Sets the useUserOverride value to false.
      Thread.CurrentThread.CurrentCulture = new CultureInfo("fr-FR", _
         false);
      // Displays i formatted as currency for the CurrentCulture.
      // This will override any user settings and display the euro symbol.
      return (i.ToString("c"));
   }
}

我在下面编写代码来获取货币格式模式。

此处，将param numberFormat作为 [Currency]＃，## 0.00 和 fr-FR 区域设置传递;并且 ### 0,00“€”作为愿望和预期的o / p。

static string[] CurrencyPositivePattern = { "$n", "n$", "$ n", "n $" };
static string[] CurrencyNegativePattern = { "($n)", "-$n", "$-n", "$n-", "(n$)", 
                        "-n$", "n-$", "n$-", "-n $", "-$ n",
                        "n $-", "$ n-", "$ -n", "n- $", "($ n)",
                        "(n $)" };

    internal static string GetCurrencyPattern(System.Globalization.NumberFormatInfo numberFormatInfo, string numberFormat)
    {
        numberFormat = numberFormat.Replace("[Currency]", string.Empty);
        int pos = numberFormatInfo.CurrencyPositivePattern;
        int neg = numberFormatInfo.CurrencyNegativePattern;
        string currencySymbol = string.Format("\"{0}\"", numberFormatInfo.CurrencySymbol);
        string excelPattern = string.Concat(CurrencyPositivePattern[pos].Replace("n", numberFormat).Replace("$", currencySymbol),
            ";",
             CurrencyNegativePattern[neg].Replace("n", numberFormat).Replace("$", currencySymbol));
        return excelPattern;
    }

我用于实施的参考文献很少： https://msdn.microsoft.com/en-us/library/system.globalization.numberformatinfo.currencynegativepattern(v=vs.110).aspx https://msdn.microsoft.com/en-us/library/system.globalization.numberformatinfo.currencypositivepattern(v=vs.110).aspx

当我坚持使用特定的货币格式的excel时，我会编写特定于货币的代码。其他格式很容易通过excel处理（同样也由 Murray Foxcroft 在评论的评论中评论）。
