推荐答案

TreeNode类具有Expand方法，您可以使用该并使用Parent属性向上移动树扩大所有父母. (可选)您可以使用EnsureVisible方法为您完成所有操作. (已编辑，您只想扩展子节点，而不是父节点).

您应该真正尝试阅读文档 [

The TreeNode class has an Expand method, you could use that and walk up the tree using the Parent property to expand all parents. Optionally you could use the EnsureVisible method which does all of that for you. (edited, you only want to expand child nodes, not parent nodes).

You should really try reading the documentation[^] sometime. It''ll help you discover the answers to question like this all by yourself.
