Encrypt custom ConfigurationSe ction in .Net 2.0

[Alex Sadomov]

Hi all
I have a custom configuration section in the App.config file of the console
application:
---------------------------------------------------------------------------
<configuratio n>
<configSections >
<section name="MySection " type="..."/>
</configSections>

<MySection>
<MySectionGroup s>
<add name="Group1">
<add name="connectio nString1" connectionStrin g="..." providerName=". .."
/>
<add name="connectio nString2" connectionStrin g="..." providerName=". .."
/>
</add>
<add name="Group2">
<add name="connectio nString1" connectionStrin g="..." providerName=". .."
/>
<add name="connectio nString2" connectionStrin g="..." providerName=". .."
/>
</add>
</MySectionGroups >
</MySection>

....
</configuration>
---------------------------------------------------------------------------
How you can see it contains groups of connections strings used by application.

Is there any method to encrypt the data by standard way? The following code
works fine with standard sections (like <connectionStri ngs>), but throws
an InvalidOperatio nException with my section:

Configuration config = ConfigurationMa nager.OpenExeCo nfiguration(Con figurationUserL evel.None);
MyConfigSection section =
(MyConfigSectio n)Configuration Manager.GetSect ion("MyConfigSe ction");
if (!section.Secti onInformation.I sProtected)
{
section.Section Information.Pro tectSection("Da taProtectionCon figurationProvi der");
}

config.Save();

By "standard way" I mean not to implement special logic to encrypt/decrypt
settings each time they retrieved from config. Assume that this encryption
operation will be performed once and .Net will work correctly with it by
hiding encrypt/decrypt logic (as is does for standard sections)
