实现效果：

注意：页面分别拖拽两个Button和一个Label控件

WebForm1.aspx.cs主要代码：

        protected void btnWrite_Click(object sender, EventArgs e)
        {
            string path = Server.MapPath("test.xml");
            XmlTextWriter xml = new XmlTextWriter(path, System.Text.Encoding.UTF8);
            //xml文件的头部信息
            xml.WriteStartDocument();
            //自定义标签
            xml.WriteStartElement("stuInfo");
            xml.WriteStartElement("student");
            xml.WriteElementString("stuName", "彬菌");
            xml.WriteElementString("stuUrl", "www.idaobin.com");
            //student标签的关闭标签
            xml.WriteEndElement();
            xml.WriteStartElement("student");
            xml.WriteElementString("stuName", "彬酱");
            xml.WriteElementString("stuUrl", "www.idaobin.com/life");
            //student标签的关闭标签
            xml.WriteEndElement();
            //stuInfo标签的关闭标签
            xml.WriteEndElement();
            xml.WriteEndDocument();
            xml.Flush();
            xml.Close();
        }
        protected void btnReader_Click(object sender, EventArgs e)
        {
            string path = Server.MapPath("test.xml");
            XmlTextReader xml = new XmlTextReader(path);
            int index = 1;
            while (xml.Read())
            {
                if (xml.NodeType == XmlNodeType.Element)
                {
                    if (xml.Name == "student")
                    {
                        this.Label1.Text += "站点 " + index + " 信息如下：<hr />";
                        index++;
                    }
                    if (xml.Name == "stuName")
                    {
                        this.Label1.Text += "站点名称：" + xml.ReadElementString() + "<hr />";
                    }
                    if (xml.Name == "stuUrl")
                    {
                        this.Label1.Text += "站点链接：" + xml.ReadElementString() + "<hr />";
                    }
                }
            }
        }
