)

Parameters

node

The node searched for within the list.

Return Value

True when node exists within the list; otherwise False.

Implementations of IUIHierarchyNode that require the Contains method to function based on a node's value equivalency must override Equals and GetHashCode when their class implements IUIHierarchyNode, otherwise only reference comparison is performed by this method.
