奇怪的解析Double行为

Question

I have this line of code:

return (this.pretWithoutDiscount / Double.Parse(UtilsStatic.getEuroValue())).ToString("N2") + "€";

In debug mode i've tested and the values are:

UtilsStatic.getEuroValue() = "4.1878"

this.pretWithoutDiscount = 111.0

Can anyone explaing WHY:

Double.Parse(UtilsStatic.getEuroValue()) = 41878.0

when it should be 4.1878 ??

Thanks...

PS: UtilsStatic.getEuroValue returns a string.

Answer 1

What decimal seprator are you using, my guess would be ','. Try

Double.Parse(UtilsStatic.getEuroValue(), 
             System.Globalization.CultureInfo.InvariantCulture) 

which will parse the number using '.' as the decimal separator.

Answer 2

看来您正在处理金钱，因此应使用decimal类型而不是double 。
