Hi,

I'm reading data from XML. Some of them denote prices. There is a problem that some prices are for example 1562,0000. There is more zeros than is normal :-) I'm sending this data out and other application shows bad prices.

Do you know how to process this data to display correctly on the other side?

thanks

Thanks for link, which methods would you use for formatting the string to remove the comma and redundant zeros?

Depending on your culture and what results you want, here is one example. It is based on same information angus_young_acdc has shown.

First given number is formatted as currency string. Note that currency is shown as specified in current culture (System.Threading.Thread.CurrentThread.CurrentCulture.NumberFormat).

Of course you might want to show result as a generic number. You can define how many digits is shown jut by adding number after format: n0, n1, n2, n3... to show specified number of digits. This is not usually mentioned in documentation.
decimal result = Convert.ToDecimal("1562,0000");
 
// Currency string -> $1,562.00 or 1 562,00 ¬
String.Format("{0:c}", result);
// Number string -> 1,562.00
String.Format("{0:n}", result);
// Number string -> 1,562
String.Format("{0:n0}", result);
// Number string -> 1,562.000
String.Format("{0:n3}", result);
