C# WinForm TreeView用法总结

TreeView用法值得总结一下，今天用到了，一时忘了怎样执行选中节点事件。

private void BindTreeView()
{
    treeView1.LabelEdit = false;//不可编辑
    //添加结点
    TreeNode root = new TreeNode();
    root.Text = "根节点";
    //一级
    TreeNode node1 = new TreeNode();
    node1.Text = "1";
    TreeNode node2 = new TreeNode();
    node2.Text = "2";
    //二级
    TreeNode node11 = new TreeNode();
    node11.Text = "11";
    TreeNode node12 = new TreeNode();
    node12.Text = "12";
    TreeNode node21 = new TreeNode();
    node21.Text = "21";
    TreeNode node22 = new TreeNode();
    node22.Text = "22";
    //二级加入一级
    node1.Nodes.Add(node11);
    node1.Nodes.Add(node12);
    node2.Nodes.Add(node21);
    node2.Nodes.Add(node22);
    //一级加入根
    root.Nodes.Add(node1);
    root.Nodes.Add(node2);
    //
    treeView1.Nodes.Add(root);
}
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
    if (treeView1.SelectedNode != null)
    {
        MessageBox.Show(treeView1.SelectedNode.Text);
    }
}
