String.Format和log.DebugFormat货币

Question

我使用log4net输出格式化消息。下面的代码

log.DebugFormat("Balance: {0:c} ", balance); 

结果

“余额：¤1,000.00”

为什么奇怪字符出现，而不是一个$

Answer 1

我会想象它是事做您的区域设置。

尝试这样：

System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(<your culture setting>); 
log.DebugFormat("Balance: {0:c} ", balance); 

如果这么想的工作，那么你可以随时使用调试器来检查的值：

System.Threading.Thread.CurrentThread.CurrentCulture.NumberFormat ;

具体检查的值：

ansiCurrencySymbol 

为了确保它设置为“$”符号。

您也可以在此维基百科页面位数的：http://en.wikipedia.org/wiki/Currency_%28typography%29

这说明了什么，你所得到的符号。

具体做法是：

The currency sign (¤) is a character used to denote a currency, when the symbol for a particular currency is unavailable. 

It is particularly common in place of symbols, such as that of the Colón (₡), which are absent from most character sets and fonts. 

It can be described as a circle the size of a lowercase character with four short radiating arms at 45° (NE), 135° (NW), 225°, (SW) and 315° (SE). It is slightly raised over the baseline. 

It is represented in Unicode, as CURRENCY SIGN (U+00A4). In HTML, the character entity reference ¤ or numeric character reference ¤ may be used.
