可以使用XmlWriter将XML写入内存吗？

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

public class XmlWriterExample
{
    public static void Main()
    {
        // 创建一个StringBuilder对象，用于存储XML文档
        StringBuilder sb = new StringBuilder();

        // 使用StringWriter将XML文档写入StringBuilder对象
        using (StringWriter sw = new StringWriter(sb))
        {
            using (XmlWriter xw = XmlWriter.Create(sw))
            {
                // 编写XML文档
                xw.WriteStartDocument();
                xw.WriteStartElement("root");
                xw.WriteElementString("child", "value");
                xw.WriteEndElement();
                xw.WriteEndDocument();
            }
        }

        // 输出XML文档
        Console.WriteLine(sb.ToString());
    }
}
