CollectionBase.OnRemoveComplete Method

Performs additional custom processes after removing an element from the CollectionBase instance.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

protected virtual void OnRemoveComplete(
	int index,
	Object value
)

Parameters

index
Type: System.Int32

The zero-based index at which value can be found.

value
Type: System.Object

The value of the element to remove from index.

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified element is removed.

The On* methods are invoked only on the instance returned by the List property, but not on the instance returned by the InnerList property.

The collection reverts back to its previous state if one of the following occurs:

  • The process fails.

  • This method is overridden to throw an exception.

The default implementation of this method is an O(1) operation.

Notes to Implementers

This method allows implementers to define processes that must be performed after removing the element from the underlying System.Collections.ArrayList. By defining this method, implementers can add functionality to inherited methods without having to override all other methods.

OnRemove is invoked before the standard Remove behavior, whereas OnRemoveComplete is invoked after the standard Remove behavior.
