我正在C#2.0中使用带复选框的TreeView控件. TreeView中有一些项目. 我的表单中有一个按钮控件. 我需要的是，当我单击按钮时，它应该选择树中存在的所有Node-checkBox(父节点和子节点).

I am Using TreeView Control in C# 2.0 with checkboxes. There are some Items in the TreeView. There is a Button Control in my form. What I need is when I click the Button it should Select all the Node-checkBoxes present in tree(Parent as well as child nodes).

推荐答案

如果这是表格，例如，您可以遍历每个根节点并调用递归方法以检查该节点及其子节点.例如: 迭代: If this is forms, you can for example iterate through each root node and call a recursive method to check that node and it''s children. For example: Iteration: foreach (TreeNode node in treeView1.Nodes) { CheckItems(node); }

递归方法:

Recursive method:

private void CheckItems(TreeNode node) { node.Checked = true; foreach (TreeNode childNode in node.Nodes) { childNode.Checked = true; CheckItems(childNode); } }
