推荐答案

树形视图设计为一次只能选择一个节点，这很好. br/>
您需要选择一些单个树节点并将其属性Selected分配为true:

选择一个节点完全等同于选择一棵子树，因为一个节点明确表示某个子树.节点本身只有在没有子节点的情况下才是子树，但是如果该节点以及所有子节点(直接子节点和间接子节点)始终是子树，则节点集是一致的.并且，每个子树都由整个树的某个节点明确表示.问题解决了.

Tree views are designed to select no more than one node at a time, and this is perfectly fine.

You need to pick some single tree node and assign its property Selected to true:

Selecting one node is fully equivalent to selecting a sub-tree, because one node unambiguously represents some sub-tree. The node itself is a sub-tree only if it has no children, but the set of node consistent if this node and all children, direct and indirect, is always a sub-tree. And, every sub-tree is unambiguously represented by some node of a whole tree. Problem solved.
