This is the C# version
private void PrintLevelOrder(BinaryTreeNode node)
{
// Do a level Order Traversal
Queue<BinaryTreeNode> queue = new
Queue<BinaryTreeNode>();
queue.Enqueue(node);
while (queue.Count != 0)
{
Console.WriteLine((node = queue.Dequeue
() as BinaryTreeNode).IntValue.ToString());
if (node.Left !=null)
queue.Enqueue(node.Left as
BinaryTreeNode);
if (node.Right!=null)
queue.Enqueue(node.Right as
BinaryTreeNode);
}
}
