I have a problem with the TypeConverter
class. It works fine with CultureInvariant
values but cannot convert specific cultures like English thousands separators. Below is a small test program that I cannot get to work.
Here's the problem :) - ConvertFromString
throws an exception with the following message "2,999.95 is not a valid value for Double." and with the inner exception "Input string was not in a correct format.".
using System;
using System.Globalization;
using System.ComponentModel;
class Program
{
static void Main()
{
try
{
var culture = new CultureInfo("en");
var typeConverter = TypeDescriptor.GetConverter(typeof(double));
double value = (double)typeConverter.ConvertFromString(
null,
culture,
"2,999.95");
Console.WriteLine("Value: " + value);
}
catch (Exception e)
{
Console.WriteLine("Error: " + e.Message);
}
}
}
Edit: Link to the bug report on Connect
The DoubleConverter
that is obtained from TypeDescriptor.GetConverter(typeof(double))
end ups calling Double.Parse
with the following arguments:
Double.Parse(
"2,999.95",
NumberStyles.Float,
(IFormatProvider)culture.GetFormat(typeof(NumberFormatInfo)));
The problem is that NumberStyles.Float
does not allows thousands separators and that's why you are getting the problem. You can submit this on Microsoft Connect or see if anybody else had the same problem.
If Double.Parse
is called also with NumberStyles.AllowThousands
the problem would not occur.
Double.Parse(
"2,999.95",
NumberStyles.Float | NumberStyles.AllowThousands,
(IFormatProvider)culture.GetFormat(typeof(NumberFormatInfo)));
