public IEnumerator GetEnumerator()

Return Value

Type: System.Collections.IEnumerator

An IEnumerator that represents the tree node collection.

The following code example determines if a specified TreeNode is within a TreeNodeCollection, and then enumerates the collection. This example requires that you have a Form with a TreeView that has a TreeNodeCollection that contains a TreeNode named myTreeNode2.

private void EnumerateTreeNodes()
{
   TreeNodeCollection myNodeCollection = myTreeView.Nodes;
   // Check for a node in the collection.
   if (myNodeCollection.Contains(myTreeNode2))
   {
      myLabel.Text += "Node2 is at index: " + myNodeCollection.IndexOf(myTreeNode2);
   }
   myLabel.Text += "\n\nElements of the TreeNodeCollection:\n";

   // Create an enumerator for the collection.
   IEnumerator myEnumerator = myNodeCollection.GetEnumerator();
   while(myEnumerator.MoveNext())
   {
      myLabel.Text += ((TreeNode)myEnumerator.Current).Text +"\n";
   }
}
