如何遍历WINFORM的TREEVIEW的所有节点

Answer 1

public void PrintTreeViewNode(TreeNodeCollection node)
{
foreach (TreeNode n in node)
{
Response.Write(n.Text+",");
PrintTreeViewNode(n.ChildNodes);
}
}

调用 PrintTreeViewNode(TreeView1.Nodes);

//////////////////////////////////////////////////////////////////
private void button1_Click(object sender, EventArgs e)

{
label1.Text = string.Empty;
#region 递归
//1.获取TreeView的所有根节点
foreach (TreeNode tn in treeView1.Nodes)
{
DiGui(tn);
}
#endregion

}
private void DiGui(TreeNode tn)
{
//1.将当前节点显示到lable上
label1.Text += "aaa" + " " + tn.Text + "\r\n";
foreach (TreeNode tnSub in tn.Nodes)
{
DiGui(tnSub);
}
}
