問題描述

我的代碼最初是為英語市場編寫的，其中小數點分隔符是."所以它期望數值作為字符串使用."作為分隔符.但是我們現在在其他地方也有用戶，例如歐洲的小數點分隔符是，"的地方.

I have code that was originally written for an English language market where the decimal separator is "." so it's expecting numeric values as strings to use "." as the separator. But we now have users in other places, e.g., places in Europe where the decimal separator is ",".

因此，在我的軟件(實際上只是當前線程)的上下文中，我想將當前語言的小數分隔符覆蓋為."即使它默認為其他內容.

So, in the context of my software (really just the current thread) I want to override the decimal separator for the current language to be "." even if it defaults to something else.

我試過了

  String sep = "."; 
  NumberFormatInfo nfi1 = NumberFormatInfo.CurrentInfo;
  nfi1.NumberDecimalSeparator = sep;

但我在第三行收到Instance is read-only"異常.顯然 NumberFormatInfo 是不可寫的.那么如何將當前語言的小數點分隔符設置為默認值以外的值呢?

But I get an "Instance is read-only" exception on the third line. Apparently NumberFormatInfo is not writable. So how DO you set the current language's decimal separator to something other than its default?

推薦答案

您需要創建一個新的文化，您可以使用當前文化作為模板，只需更改分隔符.然后，您必須將當前文化設置為新創建的文化，因為您無法直接更改當前文化中的屬性.

You need to create a new culture and you can use the current culture as a template and only change the separator. Then you must set the current culture to your newly created one as you cannot change the property within current culture directly.

string CultureName = Thread.CurrentThread.CurrentCulture.Name;
CultureInfo ci = new CultureInfo(CultureName);
if (ci.NumberFormat.NumberDecimalSeparator != ".")
{
    // Forcing use of decimal separator for numerical values
    ci.NumberFormat.NumberDecimalSeparator = ".";
    Thread.CurrentThread.CurrentCulture = ci;
 }
