String to decimal conversion: dot separation instead of comma

c# decimal
LoveMyWife picture LoveMyWife · Nov 10, 2013 · Viewed 124.4k times · Source

I have a string read from a textbox. It contains a comma for decimal separation.

I have NumberFormatInfo.CurrencyDecimalSeparator set to , (comma) but when I convert the string to decimal Convert.ToDecimal(mystring); I obtain a dot separate value for decimal.

Example:

decimal a=Convert.ToDecimal("1,2345"); ----> decimal is 1.2345

I have tried also:

double a=Convert.ToDouble("1,2345");

but dot for decimal again

All this is about cultures. If you have any other culture than "US English" (and also as good manners of development), you should use something like this:

var d = Convert.ToDecimal("1.2345", new CultureInfo("en-US"));
// (or 1,2345 with your local culture, for instance)

(obviously, you should replace the "en-US" with the culture of your number local culture)

the same way, if you want to do ToString()

d.ToString(new CultureInfo("en-US"));
