The ConfigurationPropertyCollection class represents the collection of the ConfigurationProperty objects that can be attributes or ConfigurationElement objects of a configuration element.

The ConfigurationProperty class represents an individual configuration setting. It allows you to get or set the name, type, and default value for a particular configuration entity (attribute or element). Additional options allow you to specify whether the attribute is required, is an element key, or represents a default element collection.

The following example shows one possible use of the ConfigurationPropertyCollection. Refer to the example of the related type ConfigurationProperty.

<configuration>
  <configSections>
    <section name="CustomSection" type="ConfigurationPropertyExample.CustomSection, ConfigurationPropertyExample"

      restartOnExternalChanges="true" />
  </configSections>
  <CustomSection fileName="override.txt" alias="alias.txt" 
    maxUsers="1000" maxIdleTime="00:05:00" />
</configuration>
