Error while reading custom configuration file(app.config) - c#-3.0

Question

I am making a custom configuration in my winform application.
(It will represent a country-corrency list)
First the CountryList class
namespace UtilityMethods
{
public class CountryList : ConfigurationSection
{
public CountryList()
{
//
// TODO: Add constructor logic here
//
}
[ConfigurationProperty("CountryCurrency", IsRequired = true)]
public Hashtable CountryCurrencies
{
get
{
return CountryCurrency.GetCountryCurrency();
}
}
}
}
The GetCountryCurrency() method is defined in CountryCurrency class as under
namespace UtilityMethods
{
public static class CountryCurrency
{
public static Hashtable GetCountryCurrency()
{
Hashtable ht = new Hashtable();
ht.Add("India", "Rupees");
ht.Add("USA", "Dollar");
return ht;
}
}
}
The app.config file looks like
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name ="CountryList1" type ="UtilityMethods.CountryList,CountryList,Version=2.0.0.0,
Culture=neutral"/>
</configSections>
<appSettings />
</configuration>
And I am calling this from a button_click's event as
try
{
CountryList cList = ConfigurationManager.GetSection("CountryList") as CountryList;
Hashtable ht = cList.CountryCurrencies;
}
catch (Exception ex)
{
string h = ex.Message;
}
Upon running the application and clicking on the button I am getting this error
Could not load type 'UtilityMethods.CountryList' from assembly 'System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
Please help (dotnet framework : 3.5 Language: C#)

Answer 1

I figured out.Instead of using
<section name ="CountryList1" type ="UtilityMethods.CountryList,CountryList,Version=2.0.0.0, Culture=neutral"/>
It will be
<section name ="CountryList1" type ="UtilityMethods.CountryList,UtilityMethods"/>
i.e. namespace.classname,namespace
