ConfigurationElementCollection.BaseAdd Method (ConfigurationElement)

Use the BaseAdd method to add a new ConfigurationElement to the collection. Override it in a derived class if custom behavior is required when the element is added.

When adding, an element is considered a duplicate only if the keys are identical but the values are different. Elements with identical keys and values are accepted silently because the elements do not compete. However, an element with an identical key but a different value cannot be added because there is no logic to determine which of the competing values should be honored.

The following code example shows how to override the BaseAdd method and how to call it from an Add method.

public void Add(UrlConfigElement url)
{
    BaseAdd(url);

    // Your custom code goes here.

}
