Override the CreateNewElement method to create custom ConfigurationElement objects of a specific type. When a collection is loaded from the configuration file, CreateNewElement is called to create individual elements. CreateNewElement must be overridden in classes that derive from the ConfigurationElementCollection class.

The following code example shows how to override the CreateNewElement method.

Protected Overloads Overrides Function CreateNewElement() _
    As ConfigurationElement

    Return New UrlConfigElement()
End Function 'CreateNewElement

protected override 
    ConfigurationElement CreateNewElement()
{
    return new UrlConfigElement();
}
