c#构建目录树
c# Build a directory tree
我正在尝试在我的应用程序中构建目录树。
我正在使用来自 Ext.NET
的 Example。
如何在给定路径中搜索目录和子目录以构建此树?
这是示例中给出的从节点构建树的代码:
protected void NodeLoad(object sender, NodeLoadEventArgs e)
{
if (!string.IsNullOrEmpty(e.NodeID))
{
for (int i = 1; i < 6; i++)
{
AsyncTreeNode asyncNode = new AsyncTreeNode();
asyncNode.Text = e.NodeID + i;
asyncNode.NodeID = e.NodeID + i;
e.Nodes.Add(asyncNode);
}
for (int i = 6; i < 11; i++)
{
Ext.Net.TreeNode treeNode = new Ext.Net.TreeNode();
treeNode.Text = e.NodeID + i;
treeNode.NodeID = e.NodeID + i;
treeNode.Leaf = true;
e.Nodes.Add(treeNode);
}
}
}
像这样:
<script runat="server">
protected void NodeLoad(object sender, NodeLoadEventArgs e)
{
// NodeID stores the local disk path ( full path ) of the selected node to expand
string path = e.NodeID;
if (!string.IsNullOrEmpty(e.NodeID))
{
foreach(var folder in System.IO.Directory.GetDirectories(path))
{
string folderName = new System.IO.DirectoryInfo(folder).Name;
Node folderNode = new Node();
folderNode.Text = folderName;
folderNode.NodeID = folder;
e.Nodes.Add(folderNode);
}
foreach(var fileLeaf in System.IO.Directory.GetFiles(path))
{
Node treeNode = new Node();
treeNode.Text = System.IO.Path.GetFileName(fileLeaf);
treeNode.NodeID = fileLeaf;
treeNode.Leaf = true;
e.Nodes.Add(treeNode);
}
}
}
</script>
对我来说,我只是以 C:\ 为例,您需要将根文件夹放在元素中:
<Root>
<ext:Node NodeID="C:\" Text="C:\"/>
</Root>
