TreeView节点复选框选择

[huan_jin]

大家帮我看看怎么回事啊 出现错误啦 无限循环
private void treeView1_AfterCheck(object sender, TreeViewEventArgs e)
{
TreeView pTreeView = sender as TreeView;
TreeNode pTreeNode = pTreeView.SelectedNode;
if (pTreeView.SelectedNode != null)
{
if (pTreeNode.Parent != null)
{
bool pbool = pTreeNode.Checked;
if (pbool == false)
{
pTreeNode.Checked = true;

}
else
{
pTreeNode.Checked = false;

}
}
else
{
foreach (TreeNode nodes in pTreeNode.Nodes)
{
if (pTreeNode.Checked)
{
nodes.Checked = false;

}
else
{
nodes.Checked = true;

}
}
}
}
}

就是想实现 点击父节点前的复选框改变子节点前面复选框的状态 如果是子节点就直接改变子节点的状态

}
}
