String.Format 和 log.DebugFormat 货币

Question

我正在使用 log4net 输出格式化消息。以下代码的

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

结果是

“Balance: ¤1,000.00”

为什么出现奇数字符而不是 $

Answer 1

我想这与您的区域设置有关。

尝试这样的方法：

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

如果这不起作用，那么您可以随时使用调试器来检查以下值：

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

具体检查以下值：

ansiCurrencySymbol

确保将其设置为“$”符号。

这解释了您得到的符号是什么。

具体来说：

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.
