如何在C#中获取文件目录并在xml中显示

Question

这是我想要的cod，在目录中获取所有文件，在xml文件中结束写入所有文件

  private void button3_Click(object sender, EventArgs e)
    {
        XmlDocument doc = new XmlDocument();

        string appPath = Path.GetDirectoryName(Application.ExecutablePath);

        string folder = appPath;//Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName) + @"\Archive\";
        string filter = "*.*";
        string[] files = Directory.GetFiles(folder, filter);
        foreach (string item in files)
        {

            string string1 = item;
            string string2 = appPath;
            string  result = string1.Replace(string2, "");
            MessageBox.Show(result);
            doc.LoadXml("<item><name>@" + result + " </name></item>");
            // Save the document to a file and auto-indent the output.
            using (XmlTextWriter writer = new XmlTextWriter("data.xml", null))

            {
                writer.Formatting = Formatting.Indented;
                doc.Save(writer);
                writer.Close();
            }
        }
    }

使用这段代码，我将我的文件放在目录中并删除路径，例如C://folder1 1/folder1 2/bin/ app.exe到app.exe，它是可以的，但最后在xml中只需编写一个XML结果

<?xml version="1.0"?>
<item>
  <name>@\WindowsFormsApplication8.vshost.exe.manifest </name>
</item>

Answer 1

在此：

doc.LoadXml("<item><name>@" + result + " </name></item>");

每次循环重复时，都会覆盖XmlDocument中的所有XML。

如果您想要使用XmlDocument，请尝试使用它，尽管有其他(更清洁的)方法来输出XML。

        var doc = new XmlDocument();
        var root = doc.AppendChild(doc.CreateElement("Item"));

        foreach (var item in files)
        {
            var name = root.AppendChild(doc.CreateElement("Name"));
            name.InnerText = item;
        }


        var xmlWriterSettings = new XmlWriterSettings { Indent = true };
        using (var writer = XmlWriter.Create("data.xml", xmlWriterSettings))
        {
            doc.Save(writer);
        }

使用XmlSerialiser (比XDocument更干净的C#代码)：

public class Program
{
    [XmlType("Item")]
    public class Item
    {
        [XmlElement("Name")]
        public string[] Files { get; set; }
    }

    static string SerialiseToXml<T>(T obj, bool isFormatted = false)
    {
        var ns = new XmlSerializerNamespaces();
        ns.Add("", "");
        var stringBuilder = new StringBuilder();
        var xmlWriterSettings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent = isFormatted };
        using (var xmlWriter = XmlWriter.Create(stringBuilder, xmlWriterSettings))
        {
            var serializer = new XmlSerializer(obj.GetType());
            serializer.Serialize(xmlWriter, obj, ns);
            return stringBuilder.ToString();
        }
    }

    static void Main(string[] args)
    {
        string[] files = {"Apple.txt", "Orange.exe", "Pear.docx", "Banana.xml", "Papaya.xls", "Passionfruit.cs"};

        var item = new Item {Files = files};
        var xml = SerialiseToXml(item, true);

        Console.WriteLine(xml);
    }
}

你正在覆盖你的项目。

下面是编写适当xml的代码：

        XmlDocument doc = new XmlDocument();

        string appPath = Directory.GetCurrentDirectory();

        string folder = appPath;
        string filter = "*.*";
        string[] files = Directory.GetFiles(folder, filter);

        using (XmlTextWriter writer = new XmlTextWriter("data.xml", null))
        {

            writer.WriteStartDocument();

            writer.WriteStartElement("Items");

            foreach (string item in files)
            {
                string string1 = item;
                string string2 = appPath;
                string result = string1.Replace(string2, "");

                writer.WriteElementString("Item","", result);

                Console.WriteLine(result);

                writer.Formatting = Formatting.Indented;
            }

            writer.WriteEndElement();
            writer.WriteEndDocument();

            writer.Close();
            doc.Save(writer);
        }

这是示例xml，

<?xml version="1.0"?>
<Items>
  <Item>\ConsoleApplication1.exe</Item>
  <Item>\ConsoleApplication1.exe.config</Item>
  <Item>\ConsoleApplication1.pdb</Item>
  <Item>\ConsoleApplication1.vshost.exe</Item>
  <Item>\ConsoleApplication1.vshost.exe.config</Item>
  <Item>\ConsoleApplication1.vshost.exe.manifest</Item>
  <Item>\data.xml</Item>
</Items>

Answer 3

谢谢你最好的回答。我的目录中也有3个文件夹，任何文件夹中都有更多的文件，我希望文件夹中的任何文件都用xml 编写，例如。

<Items>
  <Item>\ConsoleApplication1.exe</Item>
  <Item>\ConsoleApplication1.exe.config</Item>
  <Item>\ConsoleApplication1.pdb</Item>
  <Item>\ConsoleApplication1.vshost.exe</Item>
  <Item>\ConsoleApplication1.vshost.exe.config</Item>
<Item>..folder1\gold.dll</Item>
<Item>..images\exit.png</Item>
