question about App_Code/ConfigSection.cs

Hi all,

Can anybody please tell me in brief what is going on in "App_Code/ConfigSection.cs"?
why are we calling base[] in every get method? what does it return? Thank you!

Code:

[ConfigurationProperty("defaultCacheDuration", DefaultValue = "600")]
publicint DefaultCacheDuration
{
get { return (int)base["defaultCacheDuration"]; }
set { base["defaultCacheDuration"] = value; }
}
[ConfigurationProperty("contactForm", IsRequired=true)]
publicContactFormElement ContactForm
{
get { return (ContactFormElement) base["contactForm"]; }
}

In brief the configSection.cs is used to read the name value pairs in the Web.config file. If you collapse the code down to the individual classes in configSetion.cs you will see the first class is TheBeerHouseSection, which matches a section in the webconfig. In the TheBeerHouse section of the web.config are several elements, which have matching *Element classes in the configSection.cs; and each *Element class has read only properties in TheBeerHouseSection class.

If you want to create your own module, say a module for resources/links, you would need to add a corresponding class to the configSection.cs, add a read only property to the *Section class and an element to the Web.confg.

As for the base, it is refering to the base class (either ConfigurationSection or ConfigurationElement)

Hopefully that helps you.
