ConfigurationSection and ConfigurationProperty validation

[koleraba]

Hi.

I created a CustomSection class by extending the ConfigurationSection. I red quite a few articles on the subject and they all sugest the same approach, but it doesn't work for me, and I dont have a clue what am I doing wrong. So any idea or help will be appreciated. Below is a simplified code:

namespace ConfigElementTest
{
public static class Globals
{
public static MySection Settings;

public static void Load()
{
try
{
Settings = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None).GetSection("mySection") as MySection;
}
catch (Exception ex)
{

}
}
}

public class MySection : ConfigurationSection
{
public MySection()
{

}

[ConfigurationProperty("name"), StringValidator(MaxLength = 10, MinLength = 3)]
public string Name
{
get{return (string) base["name"];}
set { base["name"] = value; }
}
}
}

And here is my app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="mySection" type="ConfigElementTest.MySection, ConfigElementTest" />
</configSections>
<mySection name="Some Name" />
</configuration>

When I call the Globals.Load() method an exception is thrown saying that the name has to be at least 3 characters long. If I remove the validator, everything works fine and if i call Globals.Settings.Name I get the right value - "Some Name" - as specified in app. config

Thanks in advance,
Uros
