The following example finds all the nodes that are linked to the ContextNode, selectedNode. If selectedNode is not a destination node, the destination node is added to an ArrayList, destinationNodes. If selectedNode is not the source node, it is added to an ArrayList, sourceNodes.

Dim destinationNodes As New ArrayList()
Dim sourceNodes As New ArrayList()

' Find all the nodes that link to the currently selected node.
Dim link As ContextLink
For Each link In  selectedNode.Links
    If link.DestinationNode <> selectedNode Then
        destinationNodes.Add(link.DestinationNode)
    End If
    
    If link.SourceNode <> selectedNode Then
        sourceNodes.Add(link.SourceNode)
    End If
Next link

ArrayList destinationNodes = new ArrayList();
ArrayList sourceNodes = new ArrayList();

// Find all the nodes that link to the currently selected node.
foreach (ContextLink link in selectedNode.Links)
{
    if (link.DestinationNode != selectedNode)
    {
        destinationNodes.Add(link.DestinationNode);
    }

    if (link.SourceNode != selectedNode)
    {
        sourceNodes.Add(link.SourceNode);
