IndexOf Method (IUIHierarchyNodeList)

Gets the index of a specific IUIHierarchyNode within the list, if it exists.

Syntax

Visual Basic

'Declaration

int IndexOf( 
   IUIHierarchyNode node
)

Parameters

node

The node searched for within the list.

Return Value

The index of node within the list if present; otherwise -1.

Remarks

Implementations of IUIHierarchyNode that require the IndexOf 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.
