The TreeNode object to append.

Use the Add method to append the specified TreeNode object to the end of the TreeNodeCollection.

NoteNote:

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

As an alternative, you can insert a TreeNode object in the TreeNodeCollection at a specific index by using the AddAt method.

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