Decimal.Parse throws a FormatException

Question

I tried to use the decimal.parse as described at : http://msdn.microsoft.com/en-us/library/cafs243z(v=vs.110).aspx

So i copied from this page the following example:

   string value;
   decimal number;
   value = "1.62345e-02";
   try
   {
       number = Decimal.Parse(value);
       Console.WriteLine("'{0}' converted to {1}.", value, number);
   }
   catch (FormatException)
   {
       Console.WriteLine("Unable to parse '{0}'.", value);
   }

And i got a FormatException, Do you have an idea why it's happened?

thanks, eyal

Try this:

using System.Globalization;
using System.Text;

....

number = Decimal.Parse(value, NumberStyles.AllowExponent|NumberStyles.AllowDecimalPoint);

In order to parse a number in exponential format, you need to set the appropriate flags from NumberStyles Enumeration as described here.
