Convert.ToDouble(“4089.90”) outputs 40.899,00 why?

Question

I am developing a software that uses number precision, but I have this problem, it happens that when I take a string to convert to double it outputs me with a different culture.

Answer 1

Actually is very rare this behaviour cause all the machines have the same culture settings, however I think that the best solution would be to modify the web.config like this:

configuration>
  
    
  

And apply the settings for the entire application.

Thanx everyone for your assistance.
