转换为浮点数时的C#问题 [英] C# problem when converting to float

问题描述

你好！

我想转换为浮点数.我知道这是很简单的事情，但是很难找到解决这个问题的方法...
所以这是代码:

Hello!

I wanted to convert to float. I know, it is very simple thing to do, but it''s harder to find a solution to this problem...
So heres the code:

string s = "1.1"
float f = float.Parse(s);

现在我得到一个formatexception.我不知道为什么?！

Now I get a formatexception. I can''t figure out why?!

推荐答案

最可能出现此错误的原因是您的区域设置对使用了不同的字符. (小数点)

试试:

The most likely reason for your error is that your regional settings use a different character for . (decimal point)

Try:

float.Parse(s, CultureInfo.InvariantCulture);

此代码如果添加缺少的;"，则按预期工作第一行之后-mdash;在默认区域性中.
您的线程文化是什么?也许，"应作为分数定界符(小数点)—因为文化不同?

This code works as you expect if you add missing ";" after first line — in default culture.
What is your thread culture? Maybe "," is expected as fraction delimiter (decimal point) — due to different culture?
