XML :如何将StreamReader中的字符串输出为.NET

using System;
using System.IO;
using System.Xml;

public class Program
{
    public static void Main()
    {
        // 从StreamReader中读取XML字符串
        string xmlString = "<root><name>John Doe</name><age>30</age></root>";
        using (StringReader stringReader = new StringReader(xmlString))
        {
            using (XmlReader xmlReader = XmlReader.Create(stringReader))
            {
                // 创建XmlWriter来输出.NET
                XmlWriterSettings settings = new XmlWriterSettings();
                settings.Indent = true; // 设置缩进
                using (XmlWriter xmlWriter = XmlWriter.Create(Console.Out, settings))
                {
                    // 读取XML并输出为.NET
                    while (xmlReader.Read())
                    {
                        switch (xmlReader.NodeType)
                        {
                            case XmlNodeType.Element:
                                xmlWriter.WriteStartElement(xmlReader.Name);
                                break;
                            case XmlNodeType.Text:
                                xmlWriter.WriteString(xmlReader.Value);
                                break;
                            case XmlNodeType.EndElement:
                                xmlWriter.WriteEndElement();
                                break;
                        }
                    }
                }
            }
        }
    }
