如何在ASP.NET中返回XML？

using System.Xml;

public class XmlGenerator
{
    public XmlDocument GenerateXml()
    {
        XmlDocument xmlDoc = new XmlDocument();

        // 创建XML声明
        XmlDeclaration xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);
        xmlDoc.AppendChild(xmlDeclaration);

        // 创建根节点
        XmlElement rootElement = xmlDoc.CreateElement("Root");
        xmlDoc.AppendChild(rootElement);

        // 创建子节点
        XmlElement childElement = xmlDoc.CreateElement("Child");
        childElement.InnerText = "Hello, World!";
        rootElement.AppendChild(childElement);

        return xmlDoc;
    }
}

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Xml" %>
<%@ Import Namespace="YourNamespace.XmlGenerator" %><script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        XmlGenerator generator = new XmlGenerator();
        XmlDocument xmlDoc = generator.GenerateXml();
        Response.Clear();
        Response.ContentType = "text/xml";
        xmlDoc.Save(Response.Output);
        Response.End();
    }
</script>
