Best way to parse float?

Question

What is the best way to parse a float in CSharp? I know about TryParse, but what I\'m particularly wondering about is dots, commas etc.

I\'m having problems with my

Answer 1

Use a neutral culture (or one you know) when parsing with Try/Parse.

Answer 2

If you want persist values ( numbers, date, time, etc... ) for internal purpose. Everytime use "InvariantCulture" for formating & parsing values. "InvariantCulture" is same on every computer, every OS with any user's culture/language/etc...

string strFloat = (15.789f).ToString(System.Globalization.CultureInfo.InvariantInfo);
float numFloat  = float.Parse(System.Globalization.CultureInfo.InvariantInfo, strFloat);
string strNow   = DateTime.Now.ToString(System.Globalization.CultureInfo.InvariantInfo);
DateTime now    = DateTime.Parse(System.Globalization.CultureInfo.InvariantInfo, strNow);

Answer 3

Try to avoid float.Parse, use TryParse instead as it performs a lot better but does the same job. this also applies to double, DateTime, etc...

(some types also offer TryParseExact which also performs even better!)

Answer 4

you can know current Cuklture of your server with a simple statement:

System.Globalization.CultureInfo culture = System.Globalization.CultureInfo.CurrentCulture;

Note that there id a CurrentUICulture property, but UICulture is used from ResourceMeanager form multilanguages applications. for number formatting, you must considere CurrentCulture.

I hope this will help you
