Creating XML file representing folder structure (including subfolders) in C#
提问by Deepanjan Nag
How can produce an XML file structuring a given folder to recursively represent all the files & subfolders within it?
如何生成构造给定文件夹的 XML 文件以递归表示其中的所有文件和子文件夹？

That's great example of problem, that can be easily solved using recursive algorithm!
这是一个很好的问题示例，可以使用递归算法轻松解决！
Pseudo-code:
伪代码：
function GetDirectoryXml(path)
xml := "<dir name='" + path + "'>"
dirInfo := GetDirectoryInfo(path)
for each file in dirInfo.Files
xml += "<file name='" + file.Name + "' />"
end for
for each subDir in dirInfo.Directories
xml += GetDirectoryXml(subDir.Path)
end for
xml += "</dir>"
return xml
end function
It can be done with C# and DirectoryInfo/XDocument/XElementclasses like that:
它可以用C＃和做DirectoryInfo/ XDocument/XElement这样的类：
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;
}
And example of usage:
和用法示例：
static void Main(string[] args)
{
string rootPath = Console.ReadLine();
var dir = new DirectoryInfo(rootPath);
var doc = new XDocument(GetDirectoryXml(dir));
Console.WriteLine(doc.ToString());
Console.Read();
}
Output for one of directories on my laptop:

It's a bit hard to know what's the problem you are having.
很难知道您遇到了什么问题。
You'll need to use DirectoryInfo.GetFilesand DirectoryInfo.GetDirectoriesto get the list of files and folder, loop with recursion. Then use the Xml.XmlDocument to write the xml document.
您需要使用DirectoryInfo.GetFiles和DirectoryInfo.GetDirectories来获取文件和文件夹列表，递归循环。然后使用 Xml.XmlDocument 编写xml 文档。
