c# - 将括号(负)转换为双

Question

你好我如何将括号格式的负值转换为 double 值。目前我有这个。

Payment.Text = Calc_Payment().ToString("#,##0.00;(#,##0.00)");

将支付转换为 Bracket 格式但我想做相反的事情。括号格式的字符串为 Double。如果有人可以帮忙请。

请尝试以下操作:

// using System.Globalization
double d = double.Parse("(1,000.90)", NumberStyles.AllowParentheses | 
                                      NumberStyles.AllowThousands | 
                                      NumberStyles.AllowDecimalPoint)

/* d = -1000.9 */

引用。 Double.Parse Method (String, NumberStyles) ; NumberStyles Enumeration

注意: “十进制”类型可以更好地处理货币值。来自documentation :

Compared to floating-point types, the decimal type has more precision and a smaller range, which makes it appropriate for financial and monetary calculations.
