Question

I need to convert a string to a monetary format of {###}.###.###,##

that is

a value of 5461497702600

would become

54.614.977.026,00

The numbers become excessively large.

I am using

return string.Format("{0:#" + (val < 1000 ? "" : "\\.") + "##0.00}", val);

which returns for the example

54614977.026,00

(only one dot)

Any help would be appreciated

Answer 1

It is simpler than you seem to think, just use:

   decimal number = 5461497702600M;
   string s = string.Format("{0:#,##0.00}", number );

It is essential to use decimal here. The #,##0.00 picture is a very standard way of doing this, the output will use the system default symbols and the fromatter is smart enough to repeat the 3 digit grouping as needed. Use the following overload to specify a Culture, this example with the InvariantCulture will always use a decimal point:

 string s = string.Format(System.Globalization.CultureInfo.InvariantCulture, 
      "{0:#,##0.00}", number);
