How to remove checked nodes in c# treeview?

Question

Hi all,

 

My codes:

 

private void btnRemove_Click(object sender, EventArgs e)

{

     RemoveCheckedNodes(treeView1.Nodes);

}

private void RemoveCheckedNodes(TreeNodeCollection nodes)

{

foreach (TreeNode node in nodes)

{

if (node.Checked)

{

nodes.Remove(node);

}

else

{

RemoveCheckedNodes(node.Nodes);

}

}

}

 

 

Thanks.
