ConfigurationElementCollection.CreateNewElement Method (String)

Creates a new ConfigurationElement when overridden in a derived class.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

protected virtual ConfigurationElement CreateNewElement(
	string elementName
)

Parameters

elementName
Type: System.String

The name of the ConfigurationElement to create.

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.

Notes to Implementers:

If you create a custom ConfigurationElementCollection collection that contains heterogeneous ConfigurationElement types, you must perform these steps:

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

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