public:
void Add(
	TreeNode^ child
)

Parameters

child
Type: System.Web.UI.WebControls::TreeNode
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.
