问题描述
我决定用另一个程序来测试创建一个包含目录的所有文件夹条带的XML文件。运行良好，创建文件是正确的。这是代码：
I decided to do another program to test the creation of A XML file with all folder strocture of a directory. Is working well, the file is created think correctly. Here's the code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Diagnostics;
using System.Xml;
using System.Xml.Linq;
namespace generate_XML_open_folder
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button_generate_XML_Click(object sender, EventArgs e)
{
string rootPath = combobox_rootpath.Text;
var dir = new DirectoryInfo(rootPath);
var doc = new XDocument(GetDirectoryXml(dir));
doc.Save("test.xml");
}
private void button_open_folder_Click(object sender, EventArgs e)
{
}
private void textbox_folder_to_find_TextChanged(object sender, EventArgs e)
{
}
private void combobox_rootpath_SelectedIndexChanged(object sender, EventArgs e)
{
combobox_rootpath.Items.Clear();
foreach (string s in Directory.GetLogicalDrives())
{
combobox_rootpath.Items.Add(s);
}
}
public static XElement GetDirectoryXml(DirectoryInfo dir)
{
var info = new XElement("dir",
new XAttribute("name", dir.Name));
//foreach (var file in dir.GetFiles())
// info.Add(new XElement("file",
// new XAttribute("name", file.Name)));
foreach (var subDir in dir.GetDirectories())
info.Add(GetDirectoryXml(subDir));
return info;
}
}
}
这是一个示例，内容为XML文件：
Here is an example with the content of the XML file:
<?xml version="1.0" encoding="utf-8"?>

推荐答案
var doc = XDocument.Load("test.xml");
var folderToFind = textbox_folder_to_find.Text;
var paths = doc.Descendants("dir")
.Where(dir => string.Equals(folderToFind, (string)dir.Attribute("name"), StringComparison.OrdinalIgnoreCase))
.Select(dir => dir.AncestorsAndSelf().Select(el => (string)el.Attribute("name")).Reverse().Aggregate(string.Empty, Path.Combine))
;
foreach (string path in paths)
{
Process.Start(new ProcessStartInfo
{
FileName = path,
UseShellExecute = true,
Verb = "open"
});
}
To solve the issues you raised in the comments, you’ll need to change how you generate the XML file:
To solve the issues you raised in the comments, you'll need to change how you generate the XML file:
public static XElement GetDirectoryXml(DirectoryInfo root)
{
if (root == null) throw new ArgumentNullException("root");
if (!root.Exists) throw new DirectoryNotFoundException(string.Format("The directory '{0}' does not exist.", root.FullName));
var result = new XElement("dir", new XAttribute("name", root.FullName));
BuildDirectoryXml(root, result);
return result;
}
private static void BuildDirectoryXml(DirectoryInfo currentPath, XElement parentElement)
{
try
{
foreach (var subDirectory in currentPath.EnumerateDirectories())
{
var element = new XElement("dir", new XAttribute("name", subDirectory.Name));
BuildDirectoryXml(subDirectory, element);
parentElement.Add(element);
}
}
catch (UnauthorizedAccessException)
{
}
