本文介绍了我如何检查是否目录被锁定在一个TreeView?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个 TreeView控件的地图和填充目录中的所有文件夹,我传递变量 virtualPath

时有任何功能或属性,可以告诉我,如果该目录被堵塞或不堵塞?
所以,我可以显示信息给用户说,他没有权限访问该目录。

 的String [] =目录Listdirectories(virtualPath.ToString());的foreach(在目录字符串目录){
    节点=新RadTreeNode(Path.GetDirectoryName(目录的ToString()));
    node.Value = virtualPath +\\\\+ Path.GetFileName(目录的ToString());
    parentNode.Nodes.Add(节点);
}


解决方案

虽然树形填充标记所需的节点有:
node.Tag =LOCK

然后用

 私人无效trv_SourceFolder_BeforeExpand(对象发件人,TreeViewCancelEventArgs E)
    {
        如果(Convert.ToString(e.Node.Tag)==LOCK)
            e.Cancel =真;
    }

I have a TreeView that maps and populates all the folders in a directory, I'm passing in the variable virtualPath

Is there is any function or property that can tell me if the directory is blocked or not blocked? So that I can show a message to the user saying that he does not have privileges to access the directory.

String[] directories= Listdirectories(virtualPath.ToString());

foreach (string directory in directories) {
    node = new RadTreeNode(Path.GetDirectoryName(directory .ToString()));
    node.Value = virtualPath + "\\" + Path.GetFileName(directory .ToString());
    parentNode.Nodes.Add(node);
}

解决方案

While populating Treeview Tag the required nodes with : node.Tag="LOCK"

Then use

    private void trv_SourceFolder_BeforeExpand(object sender, TreeViewCancelEventArgs e)
    {
        if (Convert.ToString(e.Node.Tag) == "LOCK")
            e.Cancel = true;
    }
