推荐答案

foreach (TreeNode node in tv.Nodes)
{
node.Checked = true;
if(node.ChildNodes.Count > 0)
    checkChildNode(node);
}

private void checkChildNode(TreeNode node)
{
            foreach (TreeNode chNode in node.ChildNodes)
            {
                chNode.Checked = true;
                if (chNode.ChildNodes.Count > 0)
                    checkChildNode(chNode);
            }
}
