Assembly: System.Configuration (in system.configuration.dll)

protected internal void BaseAdd (

protected void BaseAdd (
	ConfigurationElement element, 
	boolean throwIfExists
protected internal function BaseAdd (
	element : ConfigurationElement, 
	throwIfExists : boolean
Not applicable.



The ConfigurationElement to add.


true to throw an exception if the ConfigurationElement specified is already contained in the ConfigurationElementCollection; otherwise, false.

Exception typeCondition


The ConfigurationElement to add already exists in the ConfigurationElementCollection and the throwIfExists parameter is true.

Use the optional parameter throwIfExists to throw an Exception exception if the specified ConfigurationElement object already exists in the ConfigurationElementCollection collection.

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 call the BaseAdd method.

protected override void 
    BaseAdd(ConfigurationElement element)
    BaseAdd(element, false);
    // Add custom code here.
