推荐答案

物业t检讨： .ShowRootLines =假

Treview Property: .ShowRootLines = false

在 ShowRootLines 是假的，正/负号将不会显示根节点，但仍会子节点上，如果必要。

When ShowRootLines is false, the Plus/Minus sign will not be shown for the root node, but will still show when necessary on child nodes.

随着正/负号隐藏，你可能会考虑在执行展开根节点（）方法，一旦树被填充。 。这将确保根节点显示所有第一级子节点

With the Plus/Minus sign hidden, you might consider executing the Expand() method of the root node once the tree is populated. That will make sure that the root node shows all first-level child nodes.

请注意：有一个 ShowPlusMinus 在TreeView的属性，但它的工作原理上的所有的节点。

Note: There is a ShowPlusMinus property on the TreeView, but it works on all nodes.
