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:

C#

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

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

Solution 1

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

Try:

C#

float.Parse(s, CultureInfo.InvariantCulture);

Yeah there's not much incentive for marking a post as answered, is there?

Oooooo. I wonder how difficult that would be to code: to prevent a new question until your old one is closed. 8-)

Solution 2

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?

The actual code already has the ';' (otherwise he couldn't get the 'format exception').
BTW: nice answer.

Of course it has ';' -- who would doubt? but not the text in Question.
Thank you.
