System_CAPS_noteNote

The TreeNodeCollection allows you to insert null references (Nothing in Visual Basic), as well as duplicate TreeNode objects.

As an alternative, you can append a TreeNode object to the end of the TreeNodeCollection by using the Add method.

The following example demonstrates how to use the AddAt method to programmatically add a node to the TreeNodeCollection. Notice that the Nodes and ChildNodes properties each return a TreeNodeCollection object.
