Currency string convertion

If I convert a decimal representing a money sum to a string, I preferably do it using a sum.ToString("C"). The result is something like "$123.45" or "123,45 kr", depending on your regional settings in Windows (I guess!?).

How do I convert back from the string to a decimal/float/similar? Is there a function that trims the string dependant of the regional settings?

If that doesn't work you may need to look at the specifics in the NumberFormatInfo.CurrentInfo object like below

string sep = System.Globalization.NumberFormatInfo.CurrentInfo.CurrencyDecimalSeparator;

and the currency symbol

string symbal = System.Globalization.NumberFormatInfo.CurrentInfo.CurrencySymbol;

there are some more options in there that you can then use to convert the currency string back to the a float.

Here is a very basic example

// replace the seperator either . or , or something else with a . and also replce the currency symbol with nothing
// affectively deleting it.
string sep = System.Globalization.NumberFormatInfo.CurrentInfo.CurrencyDecimalSeparator;
string sym = System.Globalization.NumberFormatInfo.CurrentInfo.CurrencySymbol;
string total = txtTotal.Text;

total = total.Replace(sep,".");
total = total.Replace(sym,"");

MessageBox.Show(total);

Thanks guys, I made it myself by:
myDecimal = decimal.Parse(myString, NumberStyles.Currency, NumberFormatInfo.CurrentInfo);

Was that the same solution as yours, J?
