Hi there,

Can anyone help.. The machine i work on is in a european culture which mean decimal points are comas and comas are decimal points

i.e 20,000.45

here is 20.000,45

Hence I have a figure that arrives in a string in the form of 20.000,45 and i convert it to a double which i store in tempDouble ... at this stage it is good.. tempDouble = 20,000.45 so now i need a string representation of it .. so i do ToString ... but his converts it back to

20.000,45

System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
                                                      nfi.NumberDecimalSeparator = ",";
                                                      nfi.NumberGroupSeparator = "";
                                                      nfi.NumberDecimalDigits = 2;      
                                                
                                                      tempDouble = double.Parse(valor,nfi);
                                                      valor = tempDouble.ToString();

What am i doing wrong?? Obviously the ToString is using the culture setup of the machine

ANy ideas?

Thanks inadvance

Ian

You need to use Double.ToString Method (IFormatProvider) overload (here and in any other place, read FxCop guidelines). ToString function without parameters depends on the current culture. To get standard number representation, use ToString(CultureInfo.InvariantCulture).
