C#搜索TreeView子节点,保留父节点的方法

本文实例讲述了c#搜索treeview子节点,保留父节点的方法。分享给大家供大家参考。具体如下：

c# 搜索treeview子节点保留父节点：

private void selectnodebyname(string name)
{
  //重新生生成树,
 inittvcatalog();
 //删除节点
 selectnode(tvcatalog.nodes, name);
}
private void selectnode(treenodecollection nodes, string name)
{
 bool del = true;
 for (int i = nodes.count - 1; i >= 0; i--)
 {
  treenode node = nodes[i];
  del = true;
  if (node.nodes.count != 0)
  {
   selectnode(node.nodes, name);
  }
  if (node.text.startswith(name, stringcomparison.ordinalignorecase))
  {
   del = false;
  }
  else
  {
   del = true;
  }
  if (del && node.nodes.count == 0)
  {
   node.remove();
  }
 }
 tvcatalog.expandall();
}

wpf搜索treeview子节点保留父节点：

private void selectnodebyname(string name)
{
 //重新生生成树,
 method = new common.publicmethod();
 method.treeviewload();
 //删除节点
 selectnode(regimesetting.common.staticvariables.treeview.items, name);
 method = null;
}
private void selectnode(itemcollection nodes, string name)
{
 bool del = true;
 for (int i = nodes.count - 1; i >= 0; i--)
 {
  treeviewitem node = nodes[i] as treeviewitem;
  del = true;
  if (node.items.count != 0)
  {
   selectnode(node.items, name);
  }
  if (node.header.tostring().startswith(name, stringcomparison.ordinalignorecase))
  {
   del = false;
  }
  else
  {
   del = true;
  }
  if (del && node.items.count == 0)
  {
   if ((node.parent as treeviewitem) != null)
    (node.parent as treeviewitem).items.remove(node);
   else
    (node.parent as treeview).items.remove(node);
  }
 }
 (regimesetting.common.staticvariables.treeview.items[0] as treeviewitem).isexpanded = true;
}

希望本文所述对大家的c#程序设计有所帮助。
