I have a question about how to handle culture while parsing doubles.
In a system price information from various servers comes together.
However the data thats given as input varies in culture.
two million and fifty cents is given as :
"2.000.000,50"
"2,000,000.50"
"2000000.50"
"2000000,50"
is there a generic way to handle these various types of input ?
No, there is no generic way. You either need to know what culture the double was formatted or all the servers need to send in a single format, say InvariantCulture.
If you guess the culture, there's a bad news waiting for you as different cultures use different decimal separator, group separator etc. So you can't.
Refer this to foresee what can go wrong if you guess.
Please see https://stackoverflow.com/a/27443540/1230816 for an answer to your examples without any cultural assumptions required.
