double.Parse显然不适用于某些国家/地区 [英] double.Parse doesn't work with some country apparently

问题描述

基本上，我有一个非常简单的计算:

Basically, I have this really simple calculation:

int bTaxPrice = int.Parse(prices[wep]);
double t = double.Parse("1." + taxes);
double price = Math.Round(t * bTaxPrice);

我将为您提供一个示例，说明计算的工作方式，先说t=1.1和bTaxPrice=1279，然后说1.1*1279 = 1406.9，但是由于四舍五入的结果，价格等于1407.

I'll give you an example for how the calculation should work, lets say t=1.1 and bTaxPrice=1279, then 1.1*1279 = 1406.9, but since I'm rounding the result the price equals 1407.

对于使用我的C#Winforms程序的另一个国家(丹麦)的某些用户，遇到了一个问题，该问题导致数字不能四舍五入，而是将小数点后的最后两位数字相加.

For some users from another country (Denmark) that are using my C# Winforms program are experiencing a problem that causes the number not to round, but to add the last 2 digits after the decimal point.

我们上述计算的结果是1407，对于他们来说是140690.

Our result for the calculation above was 1407, for them it's 140690.

我在互联网上读到了它，有些国家的小数点有些特殊.

I read about it in the internet, and some countries have something special with there decimal point.

什么是解决此类问题的好方法?

What is a good fix for this kind of issue?

推荐答案

实际上，许多国家/地区使用逗号作为小数点分隔符. 如果要使用点作为分隔符，请使用不变的CultureInfo:

Actually, many countries use a comma for their decimal separator. If you want to use the dot as a separator, use the invariant CultureInfo:

double.Parse("1." + taxes, CultureInfo.InvariantCulture);
