C# 从目录结构创建xml

我有一个包含文件的目录和包含文件的子目录，并希望从中创建xml。以下是我的文件夹结构：

C:\inputdata folder contains:
C:\inputdata\file1.txt
C:\inputdata\picture1.jpg
C:\inputdata\subfolder\picture2.jpg
C:\inputdata\subfolder\file2.txt
C:\inputdata\subfolder\anotherfolder \file3.txt
C:\inputdata\anotherfolder\

我想生成这个xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<serverfiles>
     <file name="picture1.jpg"/>
     <file name="file1.txt"/>
     <folder name="subfolder">
          <file name="picture2.jpg"/>
          <file name="file2.txt"/>
          <folder name="anotherfolder">
               <file name="file3.txt"/>
          </folder>
     </folder>
     <folder name="anotherfolder">
     </folder>
</serverfiles>

就快到了：只需要对代码进行一些小的编辑

    private const string folderLocation = @"c:\inputdata";
    static void Main(string[] args)
    {
        DirectoryInfo dir = new DirectoryInfo(folderLocation);

        // makes everything wrapped in an XElement called serverfiles.
        // Also a declaration as specified (sorry about the standalone status:
        // it's required in the XDeclaration constructor)    
        var doc = new XDocument(new XDeclaration("1.0", "UTF-8", "yes"),
             CREATEXML(dir));

        Console.WriteLine(doc.ToString());

        Console.Read();
    }

  private static XElement CREATEXML(DirectoryInfo dir, bool writingServerFiles = true)
    {
        //get directories
        var xmlInfo = new XElement(writingServerFiles ? "serverfiles" : "folder", writingServerFiles ? null : new XAttribute("name", dir.Name)); //fixes your small isue (making the root serverfiles and the rest folder, and serverfiles not having a name XAttribute)

        //get all the files first
        foreach(var file in dir.GetFiles())
        {
            xmlInfo.Add(new XElement("file", new XAttribute("name", file.Name)));
        }
            //get subdirectories
        foreach(var subDir in dir.GetDirectories())
        {
            xmlInfo.Add(CREATEXML(subDir), false);
        }
        return xmlInfo;

    }

您可以再添加一个方法来处理子目录

private static XElement CreateXML(DirectoryInfo dir)
    {
        var xmlInfo = new XElement("serverfiles");
        //get all the files first
        foreach (var file in dir.GetFiles())
        {
            xmlInfo.Add(new XElement("file", new XAttribute("name", file.Name)));
        }
        //get subdirectories
        foreach (var subDir in dir.GetDirectories())
        {
            xmlInfo.Add(CreateSubdirectoryXML(subDir));
        }
        return xmlInfo;
    }

    private static XElement CreateSubdirectoryXML(DirectoryInfo dir)
    {
        //get directories
        var xmlInfo = new XElement("folder", new XAttribute("name", dir.Name));
        //get all the files first
        foreach (var file in dir.GetFiles())
        {
            xmlInfo.Add(new XElement("file", new XAttribute("name", file.Name)));
        }
        //get subdirectories
        foreach (var subDir in dir.GetDirectories())
        {
            xmlInfo.Add(CreateSubdirectoryXML(subDir));
        }
        return xmlInfo;
    }

添加了排序：

我认为这个解决方案会更好

        //get directories
        var xmlInfo = new XElement("folder",                 
            new XElement("name", dir.Name),
            new XElement("lastModify", dir.LastWriteTime),
            new XElement("Attributes", dir.Attributes));

        //get subdirectories
        foreach (var subDir in dir.GetDirectories())
        {
            xmlInfo.Add(CREATEXML(subDir));
        }

        //get all the files
        foreach (var file in dir.GetFiles())
        {
            xmlInfo.Add(new XElement("File",
                new XElement("name", file.Name),
                new XElement("size", file.Length),
                new XElement("lastModify", file.LastWriteTime),
                new XElement("Attributes", file.Attributes.ToString())));
        }
        return xmlInfo;

谢谢你的回答。。我现在唯一的问题是它列出了inputdata文件夹。还有，我该如何按名字对它们进行分类呢？@NikolaDavidovic不，它只是包装了一切。根据请求。@NikolaDavidovic:如果您想按名称排序，您必须扫描目录并将其存储在树结构中，进行排序，然后输出XML。您不能在一次操作中完成扫描、排序和XML流。@JimMischel感谢您为我向他解释。@NikolaDavidovic是的，它缺少缩进！喘息可怕的这不是实际的输出：输出将有一个XML声明；谢谢你的回答。。我现在唯一的问题是它列出了inputdata文件夹。还有，我该如何按名字对它们进行分类呢？@NikolaDavidovic不，它只是包装了一切。根据请求。@NikolaDavidovic:如果您想按名称排序，您必须扫描目录并将其存储在树结构中，进行排序，然后输出XML。您不能在一次操作中完成扫描、排序和XML流。@JimMischel感谢您为我向他解释。@NikolaDavidovic是的，它缺少缩进！喘息可怕的这不是实际的输出：输出将有一个XML声明；感谢您删除了第一个文件夹名称…我现在如何排序？我应该将其放入字典还是有更好的方法？感谢您删除了第一个文件夹名称…我现在如何排序？我应该将其放入字典还是有更好的方法？
