Convert string to decimal with point or comma based on current culture

Question

Depending of browser language I am getting string like

123.22

or

123,22

So sometimes I am facing an exception here

Convert.ToDecimal(item.UnitPrice);

I would like to create some expression so the convertion should be done based on current culture. Is it possible to do?

Answer 1

You didn't tell us what is your CultureInfo but anyway..

Let's assume your NumberFormatInfo.NumberDecimalSeparator is , instead of .

Your string 123,22 works well like;

string s = "123,23";
decimal d = Convert.ToDecimal(s, CultureInfo.CurrentCulture); //123,23

If your string is 123.22, then you can use String.Replace method for replacing , instead of . like;

string s = "123.23";
if(s.Contains('.'))
   s = s.Replace('.', ',');
decimal d = Convert.ToDecimal(s, CultureInfo.CurrentCulture); //123,23

Answer 2

Convert.ToDecimal() is already using the CultureInfo.CurrentCulture, it is just not set to the same value as the browser.

You could try specifying in the web.config file that the current culture be inherited from the browser: http://msdn.microsoft.com/en-us/library/bz9tc508.aspx

Usually a better direction would be to make sure the browser submits consistent values not depending on the browser language.
